The special characters used in shell-style wildcards are: Pattern 意義 `*` matches everything `?` matches any single character `[seq]` matches any character in *seq* `[!seq]` matches any character not in *seq* For a literal match, wrap the meta-characters in brackets. For example, `'[?]'` matches the character `'?'`. Note that the filename separator (`'/'` on Unix) is *not* special to this module. See module [`glob`](glob.xhtml#module-glob "glob: Unix shell style pathname pattern expansion.") for pathname expansion ([`glob`](glob.xhtml#module-glob "glob: Unix shell style pathname pattern expansion.") uses [`filter()`](#fnmatch.filter "fnmatch.filter") to match pathname segments). Similarly, filenames starting with a period are not special for this module, and are matched by the `*` and `?`patterns. `fnmatch.``fnmatch`(*filename*, *pattern*)Test whether the *filename* string matches the *pattern* string, returning [`True`](constants.xhtml#True "True") or [`False`](constants.xhtml#False "False"). Both parameters are case-normalized using [`os.path.normcase()`](os.path.xhtml#os.path.normcase "os.path.normcase"). [`fnmatchcase()`](#fnmatch.fnmatchcase "fnmatch.fnmatchcase") can be used to perform a case-sensitive comparison, regardless of whether that's standard for the operating system. This example will print all file names in the current directory with the extension `.txt`: ``` import fnmatch import os for file in os.listdir('.'): if fnmatch.fnmatch(file, '*.txt'): print(file) ``` `fnmatch.``fnmatchcase`(*filename*, *pattern*)Test whether *filename* matches *pattern*, returning [`True`](constants.xhtml#True "True") or [`False`](constants.xhtml#False "False"); the comparison is case-sensitive and does not apply [`os.path.normcase()`](os.path.xhtml#os.path.normcase "os.path.normcase"). `fnmatch.``filter`(*names*, *pattern*)Return the subset of the list of *names* that match *pattern*. It is the same as `[n for n in names if fnmatch(n, pattern)]`, but implemented more efficiently. `fnmatch.``translate`(*pattern*)Return the shell-style *pattern* converted to a regular expression for using with [`re.match()`](re.xhtml#re.match "re.match"). 示例: ``` >>> import fnmatch, re >>> >>> regex = fnmatch.translate('*.txt') >>> regex '(?s:.*\\.txt)\\Z' >>> reobj = re.compile(regex) >>> reobj.match('foobar.txt') <re.Match object; span=(0, 10), match='foobar.txt'> ``` 參見 Module [`glob`](glob.xhtml#module-glob "glob: Unix shell style pathname pattern expansion.")Unix shell-style path expansion. ### 導航 - [索引](../genindex.xhtml "總目錄") - [模塊](../py-modindex.xhtml "Python 模塊索引") | - [下一頁](linecache.xhtml "linecache --- Random access to text lines") | - [上一頁](glob.xhtml "glob --- Unix style pathname pattern expansion") | -  - [Python](https://www.python.org/) ? - zh\_CN 3.7.3 [文檔](../index.xhtml) ? - [Python 標準庫](index.xhtml) ? - [文件和目錄訪問](filesys.xhtml) ? - $('.inline-search').show(0); | ?
