ZIP 文件格式是一個常用的歸檔與壓縮標準。 這個模塊提供了創建、讀取、寫入、添加及列出 ZIP 文件的工具。 任何對此模塊的進階使用都將需要理解此格式，其定義參見 [PKZIP 應用程序筆記](https://pkware.cachefly.net/webdocs/casestudies/APPNOTE.TXT) \[https://pkware.cachefly.net/webdocs/casestudies/APPNOTE.TXT\]。
此模塊目前不能處理分卷 ZIP 文件。它可以處理使用 ZIP64 擴展（超過 4 GB 的 ZIP 文件）的 ZIP 文件。它支持解密 ZIP 歸檔中的加密文件，但是目前不能創建一個加密的文件。解密非常慢，因為它是使用原生 Python 而不是 C 實現的。
這個模塊定義了以下內容：
*exception* `zipfile.``BadZipFile`為損壞的 ZIP 文件拋出的錯誤。
3\.2 新版功能.
*exception* `zipfile.``BadZipfile`[`BadZipFile`](#zipfile.BadZipFile "zipfile.BadZipFile") 的別名，與舊版本 Python 保持兼容性。
3\.2 版后已移除.
*exception* `zipfile.``LargeZipFile`當 ZIP 文件取藥 ZIP64 功能但是未啟用時拋出此錯誤。
*class* `zipfile.``ZipFile`用于讀寫 ZIP 文件的類。 欲了解構造函數的描述，參閱段落 [ZipFile 對象](#zipfile-objects)。
*class* `zipfile.``PyZipFile`用于創建包含 Python 庫的 ZIP 歸檔的類。
*class* `zipfile.``ZipInfo`(*filename='NoName'*, *date\_time=(1980*, *1*, *1*, , , *0)*)用于表示檔案內一個成員信息的類。 此類的實例會由 [`ZipFile`](#zipfile.ZipFile "zipfile.ZipFile") 對象的 [`getinfo()`](#zipfile.ZipFile.getinfo "zipfile.ZipFile.getinfo") 和 [`infolist()`](#zipfile.ZipFile.infolist "zipfile.ZipFile.infolist") 方法返回。 大多數 [`zipfile`](#module-zipfile "zipfile: Read and write ZIP-format archive files.") 模塊的用戶都不必創建它們，只需使用此模塊所創建的實例。 *filename* 應當是檔案成員的全名，*date\_time* 應當是包含六個字段的描述最近修改時間的元組；這些字段的描述請參閱 [ZipInfo Objects](#zipinfo-objects)。
`zipfile.``is_zipfile`(*filename*)根據文件的 Magic Number，如果 *filename* 是一個有效的 ZIP 文件則返回 `True`，否則返回 `False`。 *filename* 也可能是一個文件或類文件對象。
在 3.1 版更改: 支持文件或類文件對象。
`zipfile.``ZIP_STORED`未被壓縮的歸檔成員的數字常數。
`zipfile.``ZIP_DEFLATED`常用的 ZIP 壓縮方法的數字常數。需要 [`zlib`](zlib.xhtml#module-zlib "zlib: Low-level interface to compression and decompression routines compatible with gzip.") 模塊。
`zipfile.``ZIP_BZIP2`BZIP2 壓縮方法的數字常數。需要 [`bz2`](bz2.xhtml#module-bz2 "bz2: Interfaces for bzip2 compression and decompression.") 模塊。
3\.3 新版功能.
`zipfile.``ZIP_LZMA`LZMA 壓縮方法的數字常數。需要 [`lzma`](lzma.xhtml#module-lzma "lzma: A Python wrapper for the liblzma compression library.") 模塊。
3\.3 新版功能.
注解
ZIP 文件格式規范包括自 2001 年以來對 bzip2 壓縮的支持，以及自 2006 年以來對 LZMA 壓縮的支持。但是，一些工具（包括較舊的 Python 版本）不支持這些壓縮方法，并且可能拒絕完全處理 ZIP 文件，或者無法提取單個文件。

## ZipFile 對象
*class* `zipfile.``ZipFile`(*file*, *mode='r'*, *compression=ZIP\_STORED*, *allowZip64=True*, *compresslevel=None*)打開一個 ZIP 文件，*file* 為一個指向文件的路徑（字符串），一個類文件對象或者一個 [path-like object](../glossary.xhtml#term-path-like-object)。
形參 *mode* 應當為 `'r'` 來讀取一個存在的文件，`'w'` 來截斷并寫入新的文件， `'a'` 來添加到一個存在的文件，或者 `'x'` 來僅新建并寫入新的文件。如果 *mode* 為 `'x'` 并且 *file* 指向已經存在的文件，則拋出 [`FileExistsError`](exceptions.xhtml#FileExistsError "FileExistsError")。如果 *mode* 為 `'a'` 且 *file* 為已存在的文件，則格外的文件將被加入。如果 *file* 不指向 ZIP 文件，之后一個新的 ZIP 歸檔將被追加為此文件。這是為了將 ZIP 歸檔添加到另一個文件（例如 `python.exe`）。如果 *mode* 為 `'a'` 并且文件不存在， 則會新建。如果 *mode* 為 `'r'` 或 `'a'`， 則文件應當可定位。
*compression* is the ZIP compression method to use when writing the archive, and should be [`ZIP_STORED`](#zipfile.ZIP_STORED "zipfile.ZIP_STORED"), [`ZIP_DEFLATED`](#zipfile.ZIP_DEFLATED "zipfile.ZIP_DEFLATED"), [`ZIP_BZIP2`](#zipfile.ZIP_BZIP2 "zipfile.ZIP_BZIP2") or [`ZIP_LZMA`](#zipfile.ZIP_LZMA "zipfile.ZIP_LZMA"); unrecognized values will cause [`NotImplementedError`](exceptions.xhtml#NotImplementedError "NotImplementedError") to be raised. If [`ZIP_DEFLATED`](#zipfile.ZIP_DEFLATED "zipfile.ZIP_DEFLATED"), [`ZIP_BZIP2`](#zipfile.ZIP_BZIP2 "zipfile.ZIP_BZIP2") or [`ZIP_LZMA`](#zipfile.ZIP_LZMA "zipfile.ZIP_LZMA") is specified but the corresponding module ([`zlib`](zlib.xhtml#module-zlib "zlib: Low-level interface to compression and decompression routines compatible with gzip."), [`bz2`](bz2.xhtml#module-bz2 "bz2: Interfaces for bzip2 compression and decompression.") or [`lzma`](lzma.xhtml#module-lzma "lzma: A Python wrapper for the liblzma compression library.")) is not available, [`RuntimeError`](exceptions.xhtml#RuntimeError "RuntimeError") is raised. The default is [`ZIP_STORED`](#zipfile.ZIP_STORED "zipfile.ZIP_STORED").
If *allowZip64* is `True` (the default) zipfile will create ZIP files that use the ZIP64 extensions when the zipfile is larger than 4 GiB. If it is `false` [`zipfile`](#module-zipfile "zipfile: Read and write ZIP-format archive files.") will raise an exception when the ZIP file would require ZIP64 extensions.
The *compresslevel* parameter controls the compression level to use when writing files to the archive. When using [`ZIP_STORED`](#zipfile.ZIP_STORED "zipfile.ZIP_STORED") or [`ZIP_LZMA`](#zipfile.ZIP_LZMA "zipfile.ZIP_LZMA") it has no effect. When using [`ZIP_DEFLATED`](#zipfile.ZIP_DEFLATED "zipfile.ZIP_DEFLATED") integers `0` through `9` are accepted (see [`zlib`](zlib.xhtml#zlib.compressobj "zlib.compressobj") for more information). When using [`ZIP_BZIP2`](#zipfile.ZIP_BZIP2 "zipfile.ZIP_BZIP2") integers `1` through `9` are accepted (see [`bz2`](bz2.xhtml#bz2.BZ2File "bz2.BZ2File") for more information).
If the file is created with mode `'w'`, `'x'` or `'a'` and then [`closed`](#zipfile.ZipFile.close "zipfile.ZipFile.close") without adding any files to the archive, the appropriate ZIP structures for an empty archive will be written to the file.
ZipFile is also a context manager and therefore supports the [`with`](../reference/compound_stmts.xhtml#with) statement. In the example, *myzip* is closed after the `with` statement's suite is finished---even if an exception occurs:
```
with ZipFile('spam.zip', 'w') as myzip:
myzip.write('eggs.txt')
```
3\.2 新版功能: Added the ability to use [`ZipFile`](#zipfile.ZipFile "zipfile.ZipFile") as a context manager.
在 3.3 版更改: Added support for [`bzip2`](bz2.xhtml#module-bz2 "bz2: Interfaces for bzip2 compression and decompression.") and [`lzma`](lzma.xhtml#module-lzma "lzma: A Python wrapper for the liblzma compression library.") compression.
在 3.4 版更改: ZIP64 extensions are enabled by default.
在 3.5 版更改: Added support for writing to unseekable streams. Added support for the `'x'` mode.
在 3.6 版更改: Previously, a plain [`RuntimeError`](exceptions.xhtml#RuntimeError "RuntimeError") was raised for unrecognized compression values.
在 3.6.2 版更改: The *file* parameter accepts a [path-like object](../glossary.xhtml#term-path-like-object).
在 3.7 版更改: Add the *compresslevel* parameter.
`ZipFile.``close`()Close the archive file. You must call [`close()`](#zipfile.ZipFile.close "zipfile.ZipFile.close") before exiting your program or essential records will not be written.
`ZipFile.``getinfo`(*name*)Return a [`ZipInfo`](#zipfile.ZipInfo "zipfile.ZipInfo") object with information about the archive member *name*. Calling [`getinfo()`](#zipfile.ZipFile.getinfo "zipfile.ZipFile.getinfo") for a name not currently contained in the archive will raise a [`KeyError`](exceptions.xhtml#KeyError "KeyError").
`ZipFile.``infolist`()Return a list containing a [`ZipInfo`](#zipfile.ZipInfo "zipfile.ZipInfo") object for each member of the archive. The objects are in the same order as their entries in the actual ZIP file on disk if an existing archive was opened.
`ZipFile.``namelist`()Return a list of archive members by name.
`ZipFile.``open`(*name*, *mode='r'*, *pwd=None*, *\**, *force\_zip64=False*)Access a member of the archive as a binary file-like object. *name*can be either the name of a file within the archive or a [`ZipInfo`](#zipfile.ZipInfo "zipfile.ZipInfo")object. The *mode* parameter, if included, must be `'r'` (the default) or `'w'`. *pwd* is the password used to decrypt encrypted ZIP files.
[`open()`](#zipfile.ZipFile.open "zipfile.ZipFile.open") is also a context manager and therefore supports the [`with`](../reference/compound_stmts.xhtml#with) statement:
```
with ZipFile('spam.zip') as myzip:
with myzip.open('eggs.txt') as myfile:
print(myfile.read())
```
With *mode*`'r'` the file-like object (`ZipExtFile`) is read-only and provides the following methods: [`read()`](io.xhtml#io.BufferedIOBase.read "io.BufferedIOBase.read"), [`readline()`](io.xhtml#io.IOBase.readline "io.IOBase.readline"), [`readlines()`](io.xhtml#io.IOBase.readlines "io.IOBase.readlines"), [`seek()`](io.xhtml#io.IOBase.seek "io.IOBase.seek"), [`tell()`](io.xhtml#io.IOBase.tell "io.IOBase.tell"), [`__iter__()`](../reference/datamodel.xhtml#object.__iter__ "object.__iter__"), [`__next__()`](stdtypes.xhtml#iterator.__next__ "iterator.__next__"). These objects can operate independently of the ZipFile.
With `mode='w'`, a writable file handle is returned, which supports the [`write()`](io.xhtml#io.BufferedIOBase.write "io.BufferedIOBase.write") method. While a writable file handle is open, attempting to read or write other files in the ZIP file will raise a [`ValueError`](exceptions.xhtml#ValueError "ValueError").
When writing a file, if the file size is not known in advance but may exceed 2 GiB, pass `force_zip64=True` to ensure that the header format is capable of supporting large files. If the file size is known in advance, construct a [`ZipInfo`](#zipfile.ZipInfo "zipfile.ZipInfo") object with [`file_size`](#zipfile.ZipInfo.file_size "zipfile.ZipInfo.file_size") set, and use that as the *name* parameter.
注解
The [`open()`](#zipfile.ZipFile.open "zipfile.ZipFile.open"), [`read()`](#zipfile.ZipFile.read "zipfile.ZipFile.read") and [`extract()`](#zipfile.ZipFile.extract "zipfile.ZipFile.extract") methods can take a filename or a [`ZipInfo`](#zipfile.ZipInfo "zipfile.ZipInfo") object. You will appreciate this when trying to read a ZIP file that contains members with duplicate names.
在 3.6 版更改: Removed support of `mode='U'`. Use [`io.TextIOWrapper`](io.xhtml#io.TextIOWrapper "io.TextIOWrapper") for reading compressed text files in [universal newlines](../glossary.xhtml#term-universal-newlines) mode.
在 3.6 版更改: [`open()`](functions.xhtml#open "open") can now be used to write files into the archive with the `mode='w'` option.
在 3.6 版更改: Calling [`open()`](#zipfile.ZipFile.open "zipfile.ZipFile.open") on a closed ZipFile will raise a [`ValueError`](exceptions.xhtml#ValueError "ValueError"). Previously, a [`RuntimeError`](exceptions.xhtml#RuntimeError "RuntimeError") was raised.
`ZipFile.``extract`(*member*, *path=None*, *pwd=None*)Extract a member from the archive to the current working directory; *member*must be its full name or a [`ZipInfo`](#zipfile.ZipInfo "zipfile.ZipInfo") object. Its file information is extracted as accurately as possible. *path* specifies a different directory to extract to. *member* can be a filename or a [`ZipInfo`](#zipfile.ZipInfo "zipfile.ZipInfo") object. *pwd* is the password used for encrypted files.
Returns the normalized path created (a directory or new file).
注解
If a member filename is an absolute path, a drive/UNC sharepoint and leading (back)slashes will be stripped, e.g.: `///foo/bar` becomes `foo/bar` on Unix, and `C:\foo\bar` becomes `foo\bar` on Windows. And all `".."` components in a member filename will be removed, e.g.: `../../foo../../ba..r` becomes `foo../ba..r`. On Windows illegal characters (`:`, `<`, `>`, `|`, `"`, `?`, and `*`) replaced by underscore (`_`).
在 3.6 版更改: Calling [`extract()`](#zipfile.ZipFile.extract "zipfile.ZipFile.extract") on a closed ZipFile will raise a [`ValueError`](exceptions.xhtml#ValueError "ValueError"). Previously, a [`RuntimeError`](exceptions.xhtml#RuntimeError "RuntimeError") was raised.
在 3.6.2 版更改: The *path* parameter accepts a [path-like object](../glossary.xhtml#term-path-like-object).
`ZipFile.``extractall`(*path=None*, *members=None*, *pwd=None*)Extract all members from the archive to the current working directory. *path*specifies a different directory to extract to. *members* is optional and must be a subset of the list returned by [`namelist()`](#zipfile.ZipFile.namelist "zipfile.ZipFile.namelist"). *pwd* is the password used for encrypted files.
警告
Never extract archives from untrusted sources without prior inspection. It is possible that files are created outside of *path*, e.g. members that have absolute filenames starting with `"/"` or filenames with two dots `".."`. This module attempts to prevent that. See [`extract()`](#zipfile.ZipFile.extract "zipfile.ZipFile.extract") note.
在 3.6 版更改: Calling [`extractall()`](#zipfile.ZipFile.extractall "zipfile.ZipFile.extractall") on a closed ZipFile will raise a [`ValueError`](exceptions.xhtml#ValueError "ValueError"). Previously, a [`RuntimeError`](exceptions.xhtml#RuntimeError "RuntimeError") was raised.
在 3.6.2 版更改: The *path* parameter accepts a [path-like object](../glossary.xhtml#term-path-like-object).
`ZipFile.``printdir`()Print a table of contents for the archive to `sys.stdout`.
`ZipFile.``setpassword`(*pwd*)Set *pwd* as default password to extract encrypted files.
`ZipFile.``read`(*name*, *pwd=None*)Return the bytes of the file *name* in the archive. *name* is the name of the file in the archive, or a [`ZipInfo`](#zipfile.ZipInfo "zipfile.ZipInfo") object. The archive must be open for read or append. *pwd* is the password used for encrypted files and, if specified, it will override the default password set with [`setpassword()`](#zipfile.ZipFile.setpassword "zipfile.ZipFile.setpassword"). Calling [`read()`](#zipfile.ZipFile.read "zipfile.ZipFile.read") on a ZipFile that uses a compression method other than [`ZIP_STORED`](#zipfile.ZIP_STORED "zipfile.ZIP_STORED"), [`ZIP_DEFLATED`](#zipfile.ZIP_DEFLATED "zipfile.ZIP_DEFLATED"), [`ZIP_BZIP2`](#zipfile.ZIP_BZIP2 "zipfile.ZIP_BZIP2") or [`ZIP_LZMA`](#zipfile.ZIP_LZMA "zipfile.ZIP_LZMA") will raise a [`NotImplementedError`](exceptions.xhtml#NotImplementedError "NotImplementedError"). An error will also be raised if the corresponding compression module is not available.
在 3.6 版更改: Calling [`read()`](#zipfile.ZipFile.read "zipfile.ZipFile.read") on a closed ZipFile will raise a [`ValueError`](exceptions.xhtml#ValueError "ValueError"). Previously, a [`RuntimeError`](exceptions.xhtml#RuntimeError "RuntimeError") was raised.
`ZipFile.``testzip`()Read all the files in the archive and check their CRC's and file headers. Return the name of the first bad file, or else return `None`.
在 3.6 版更改: Calling [`testzip()`](#zipfile.ZipFile.testzip "zipfile.ZipFile.testzip") on a closed ZipFile will raise a [`ValueError`](exceptions.xhtml#ValueError "ValueError"). Previously, a [`RuntimeError`](exceptions.xhtml#RuntimeError "RuntimeError") was raised.
`ZipFile.``write`(*filename*, *arcname=None*, *compress\_type=None*, *compresslevel=None*)Write the file named *filename* to the archive, giving it the archive name *arcname* (by default, this will be the same as *filename*, but without a drive letter and with leading path separators removed). If given, *compress\_type*overrides the value given for the *compression* parameter to the constructor for the new entry. Similarly, *compresslevel* will override the constructor if given. The archive must be open with mode `'w'`, `'x'` or `'a'`.
注解
Archive names should be relative to the archive root, that is, they should not start with a path separator.
注解
If `arcname` (or `filename`, if `arcname` is not given) contains a null byte, the name of the file in the archive will be truncated at the null byte.
在 3.6 版更改: Calling [`write()`](#zipfile.ZipFile.write "zipfile.ZipFile.write") on a ZipFile created with mode `'r'` or a closed ZipFile will raise a [`ValueError`](exceptions.xhtml#ValueError "ValueError"). Previously, a [`RuntimeError`](exceptions.xhtml#RuntimeError "RuntimeError") was raised.
`ZipFile.``writestr`(*zinfo\_or\_arcname*, *data*, *compress\_type=None*, *compresslevel=None*)Write a file into the archive. The contents is *data*, which may be either a [`str`](stdtypes.xhtml#str "str") or a [`bytes`](stdtypes.xhtml#bytes "bytes") instance; if it is a [`str`](stdtypes.xhtml#str "str"), it is encoded as UTF-8 first. *zinfo\_or\_arcname* is either the file name it will be given in the archive, or a [`ZipInfo`](#zipfile.ZipInfo "zipfile.ZipInfo") instance. If it's an instance, at least the filename, date, and time must be given. If it's a name, the date and time is set to the current date and time. The archive must be opened with mode `'w'`, `'x'` or `'a'`.
If given, *compress\_type* overrides the value given for the *compression*parameter to the constructor for the new entry, or in the *zinfo\_or\_arcname*(if that is a [`ZipInfo`](#zipfile.ZipInfo "zipfile.ZipInfo") instance). Similarly, *compresslevel* will override the constructor if given.
注解
When passing a [`ZipInfo`](#zipfile.ZipInfo "zipfile.ZipInfo") instance as the *zinfo\_or\_arcname* parameter, the compression method used will be that specified in the *compress\_type*member of the given [`ZipInfo`](#zipfile.ZipInfo "zipfile.ZipInfo") instance. By default, the [`ZipInfo`](#zipfile.ZipInfo "zipfile.ZipInfo") constructor sets this member to [`ZIP_STORED`](#zipfile.ZIP_STORED "zipfile.ZIP_STORED").
在 3.2 版更改: The *compress\_type* argument.
在 3.6 版更改: Calling [`writestr()`](#zipfile.ZipFile.writestr "zipfile.ZipFile.writestr") on a ZipFile created with mode `'r'` or a closed ZipFile will raise a [`ValueError`](exceptions.xhtml#ValueError "ValueError"). Previously, a [`RuntimeError`](exceptions.xhtml#RuntimeError "RuntimeError") was raised.
The following data attributes are also available:
`ZipFile.``filename`Name of the ZIP file.
`ZipFile.``debug`The level of debug output to use. This may be set from `0` (the default, no output) to `3` (the most output). Debugging information is written to `sys.stdout`.
`ZipFile.``comment`The comment associated with the ZIP file as a [`bytes`](stdtypes.xhtml#bytes "bytes") object. If assigning a comment to a [`ZipFile`](#zipfile.ZipFile "zipfile.ZipFile") instance created with mode `'w'`, `'x'` or `'a'`, it should be no longer than 65535 bytes. Comments longer than this will be truncated.
## PyZipFile Objects
The [`PyZipFile`](#zipfile.PyZipFile "zipfile.PyZipFile") constructor takes the same parameters as the [`ZipFile`](#zipfile.ZipFile "zipfile.ZipFile") constructor, and one additional parameter, *optimize*.
*class* `zipfile.``PyZipFile`(*file*, *mode='r'*, *compression=ZIP\_STORED*, *allowZip64=True*, *optimize=-1*)3\.2 新版功能: The *optimize* parameter.
在 3.4 版更改: ZIP64 extensions are enabled by default.
Instances have one method in addition to those of [`ZipFile`](#zipfile.ZipFile "zipfile.ZipFile") objects:
`writepy`(*pathname*, *basename=''*, *filterfunc=None*)Search for files `*.py` and add the corresponding file to the archive.
If the *optimize* parameter to [`PyZipFile`](#zipfile.PyZipFile "zipfile.PyZipFile") was not given or `-1`, the corresponding file is a `*.pyc` file, compiling if necessary.
If the *optimize* parameter to [`PyZipFile`](#zipfile.PyZipFile "zipfile.PyZipFile") was `0`, `1` or `2`, only files with that optimization level (see [`compile()`](functions.xhtml#compile "compile")) are added to the archive, compiling if necessary.
If *pathname* is a file, the filename must end with `.py`, and just the (corresponding `*.pyc`) file is added at the top level (no path information). If *pathname* is a file that does not end with `.py`, a [`RuntimeError`](exceptions.xhtml#RuntimeError "RuntimeError") will be raised. If it is a directory, and the directory is not a package directory, then all the files `*.pyc` are added at the top level. If the directory is a package directory, then all `*.pyc` are added under the package name as a file path, and if any subdirectories are package directories, all of these are added recursively in sorted order.
*basename* is intended for internal use only.
*filterfunc*, if given, must be a function taking a single string argument. It will be passed each path (including each individual full file path) before it is added to the archive. If *filterfunc* returns a false value, the path will not be added, and if it is a directory its contents will be ignored. For example, if our test files are all either in `test` directories or start with the string `test_`, we can use a *filterfunc* to exclude them:
```
>>> zf = PyZipFile('myprog.zip')
>>> def notests(s):
... fn = os.path.basename(s)
... return (not (fn == 'test' or fn.startswith('test_')))
>>> zf.writepy('myprog', filterfunc=notests)
```
The [`writepy()`](#zipfile.PyZipFile.writepy "zipfile.PyZipFile.writepy") method makes archives with file names like this:
```
string.pyc # Top level name
test/__init__.pyc # Package directory
test/testall.pyc # Module test.testall
test/bogus/__init__.pyc # Subpackage directory
test/bogus/myfile.pyc # Submodule test.bogus.myfile
```
3\.4 新版功能: The *filterfunc* parameter.
在 3.6.2 版更改: The *pathname* parameter accepts a [path-like object](../glossary.xhtml#term-path-like-object).
在 3.7 版更改: Recursion sorts directory entries.
## ZipInfo Objects
Instances of the [`ZipInfo`](#zipfile.ZipInfo "zipfile.ZipInfo") class are returned by the [`getinfo()`](#zipfile.ZipFile.getinfo "zipfile.ZipFile.getinfo") and [`infolist()`](#zipfile.ZipFile.infolist "zipfile.ZipFile.infolist") methods of [`ZipFile`](#zipfile.ZipFile "zipfile.ZipFile") objects. Each object stores information about a single member of the ZIP archive.
There is one classmethod to make a [`ZipInfo`](#zipfile.ZipInfo "zipfile.ZipInfo") instance for a filesystem file:
*classmethod* `ZipInfo.``from_file`(*filename*, *arcname=None*)Construct a [`ZipInfo`](#zipfile.ZipInfo "zipfile.ZipInfo") instance for a file on the filesystem, in preparation for adding it to a zip file.
*filename* should be the path to a file or directory on the filesystem.
If *arcname* is specified, it is used as the name within the archive. If *arcname* is not specified, the name will be the same as *filename*, but with any drive letter and leading path separators removed.
3\.6 新版功能.
在 3.6.2 版更改: The *filename* parameter accepts a [path-like object](../glossary.xhtml#term-path-like-object).
Instances have the following methods and attributes:
`ZipInfo.``is_dir`()Return `True` if this archive member is a directory.
This uses the entry's name: directories should always end with `/`.
3\.6 新版功能.
`ZipInfo.``filename`Name of the file in the archive.
`ZipInfo.``date_time`The time and date of the last modification to the archive member. This is a tuple of six values:
索引
值
`0`
Year (>= 1980)
`1`
Month (one-based)
`2`
Day of month (one-based)
`3`
Hours (zero-based)
`4`
Minutes (zero-based)
`5`
Seconds (zero-based)
注解
The ZIP file format does not support timestamps before 1980.
`ZipInfo.``compress_type`Type of compression for the archive member.
`ZipInfo.``comment`Comment for the individual archive member as a [`bytes`](stdtypes.xhtml#bytes "bytes") object.
`ZipInfo.``extra`Expansion field data. The [PKZIP Application Note](https://pkware.cachefly.net/webdocs/casestudies/APPNOTE.TXT) \[https://pkware.cachefly.net/webdocs/casestudies/APPNOTE.TXT\] contains some comments on the internal structure of the data contained in this [`bytes`](stdtypes.xhtml#bytes "bytes") object.
`ZipInfo.``create_system`System which created ZIP archive.
`ZipInfo.``create_version`PKZIP version which created ZIP archive.
`ZipInfo.``extract_version`PKZIP version needed to extract archive.
`ZipInfo.``reserved`必須為零。
`ZipInfo.``flag_bits`ZIP 標志位。
`ZipInfo.``volume`Volume number of file header.
`ZipInfo.``internal_attr`Internal attributes.
`ZipInfo.``external_attr`External file attributes.
`ZipInfo.``header_offset`Byte offset to the file header.
`ZipInfo.``CRC`CRC-32 of the uncompressed file.
`ZipInfo.``compress_size`Size of the compressed data.
`ZipInfo.``file_size`Size of the uncompressed file.
## 命令行界面
The [`zipfile`](#module-zipfile "zipfile: Read and write ZIP-format archive files.") module provides a simple command-line interface to interact with ZIP archives.
If you want to create a new ZIP archive, specify its name after the [`-c`](#cmdoption-zipfile-c)option and then list the filename(s) that should be included:
```
$ python -m zipfile -c monty.zip spam.txt eggs.txt
```
Passing a directory is also acceptable:
```
$ python -m zipfile -c monty.zip life-of-brian_1979/
```
If you want to extract a ZIP archive into the specified directory, use the [`-e`](#cmdoption-zipfile-e) option:
```
$ python -m zipfile -e monty.zip target-dir/
```
For a list of the files in a ZIP archive, use the [`-l`](#cmdoption-zipfile-l) option:
```
$ python -m zipfile -l monty.zip
```
