Wherever a file argument is expected, the methods accept a file-like object. For backwards compatibility, a string containing a pathname is also accepted, and the corresponding file will be opened for reading and writing; the pathname `'-'`is understood to mean the standard input or output. However, this interface is deprecated; it's better for the caller to open the file itself, and be sure that, when required, the mode is `'rb'` or `'wb'` on Windows. This code was contributed by Lance Ellinghouse, and modified by Jack Jansen. The [`uu`](#module-uu "uu: Encode and decode files in uuencode format.") module defines the following functions: `uu.``encode`(*in\_file*, *out\_file*, *name=None*, *mode=None*, *\**, *backtick=False*)Uuencode file *in\_file* into file *out\_file*. The uuencoded file will have the header specifying *name* and *mode* as the defaults for the results of decoding the file. The default defaults are taken from *in\_file*, or `'-'`and `0o666` respectively. If *backtick* is true, zeros are represented by `'`'` instead of spaces. 在 3.7 版更改: 增加 *backtick* 參數 `uu.``decode`(*in\_file*, *out\_file=None*, *mode=None*, *quiet=False*)This call decodes uuencoded file *in\_file* placing the result on file *out\_file*. If *out\_file* is a pathname, *mode* is used to set the permission bits if the file must be created. Defaults for *out\_file* and *mode* are taken from the uuencode header. However, if the file specified in the header already exists, a [`uu.Error`](#uu.Error "uu.Error") is raised. [`decode()`](#uu.decode "uu.decode") may print a warning to standard error if the input was produced by an incorrect uuencoder and Python could recover from that error. Setting *quiet* to a true value silences this warning. *exception* `uu.``Error`Subclass of [`Exception`](exceptions.xhtml#Exception "Exception"), this can be raised by [`uu.decode()`](#uu.decode "uu.decode") under various situations, such as described above, but also including a badly formatted header, or truncated input file. 參見 模塊 [`binascii`](binascii.xhtml#module-binascii "binascii: Tools for converting between binary and various ASCII-encoded binary representations.")支持模塊，包含ASCII到二進制和二進制到ASCII轉換。 ### 導航 - [索引](../genindex.xhtml "總目錄") - [模塊](../py-modindex.xhtml "Python 模塊索引") | - [下一頁](markup.xhtml "結構化標記處理工具") | - [上一頁](quopri.xhtml "quopri --- Encode and decode MIME quoted-printable data") | -  - [Python](https://www.python.org/) ? - zh\_CN 3.7.3 [文檔](../index.xhtml) ? - [Python 標準庫](index.xhtml) ? - [互聯網數據處理](netdata.xhtml) ? - $('.inline-search').show(0); | ?
