Source code: Lib/fnmatch.py
This module provides support for Unix shell-style wildcards, which are not the same as regular expressions (which are documented in the re module). The special characters used in shell-style wildcards are:
|?||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 for pathname expansion (glob uses fnmatch() to match pathname segments). Similarly, filenames starting with a period are not special for this module, and are matched by the * and ? patterns.
Test whether the filename string matches the pattern string, returning True or False. If the operating system is case-insensitive, then both parameters will be normalized to all lower- or upper-case before the comparison is performed. 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)
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.
Return the shell-style pattern converted to a regular expression.
