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|
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. If you require a case-sensitive comparison regardless of whether that’s standard for your operating system, use fnmatchcase() instead.
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 shell-style pattern converted to a regular expression.
>>> import fnmatch, re >>> >>> regex = fnmatch.translate('*.txt') >>> regex '.*\\.txt$' >>> reobj = re.compile(regex) >>> print(reobj.match('foobar.txt')) <_sre.SRE_Match object at 0x...>
