Python 3.6.5 Documentation > "glob" — Unix style pathname pattern expansion
"glob" — Unix style pathname pattern expansion **********************************************
**Source code:** Lib/glob.py
======================================================================
The "glob" module finds all the pathnames matching a specified pattern according to the rules used by the Unix shell, although results are returned in arbitrary order. No tilde expansion is done, but "*", "?", and character ranges expressed with "[]" will be correctly matched. This is done by using the "os.scandir()" and "fnmatch.fnmatch()" functions in concert, and not by actually invoking a subshell. Note that unlike "fnmatch.fnmatch()", "glob" treats filenames beginning with a dot (".") as special cases. (For tilde and shell variable expansion, use "os.path.expanduser()" and "os.path.expandvars()".)
For a literal match, wrap the meta-characters in brackets. For example, "'[?]'" matches the character "'?'".
See also: The "pathlib" module offers high-level path objects.
glob.glob(pathname, *, recursive=False)
Return a possibly-empty list of path names that match *pathname*, which must be a string containing a path specification. *pathname* can be either absolute (like "/usr/src/Python-1.5/Makefile") or relative (like "../../Tools/*/*.gif"), and can contain shell-style wildcards. Broken symlinks are included in the results (as in the shell).
If *recursive* is true, the pattern “"**"” will match any files and zero or more directories and subdirectories. If the pattern is followed by an "os.sep", only directories and subdirectories match.
Note: Using the “"**"” pattern in large directory trees may consume an inordinate amount of time.
Changed in version 3.5: Support for recursive globs using “"**"”.
glob.iglob(pathname, *, recursive=False)
Return an *iterator* which yields the same values as "glob()" without actually storing them all simultaneously.
glob.escape(pathname)
Escape all special characters ("'?'", "'*'" and "'['"). This is useful if you want to match an arbitrary literal string that may have special characters in it. Special characters in drive/UNC sharepoints are not escaped, e.g. on Windows "escape('//?/c:/Quo vadis?.txt')" returns "'//?/c:/Quo vadis[?].txt'".
New in version 3.4.
For example, consider a directory containing the following files: "1.gif", "2.txt", "card.gif" and a subdirectory "sub" which contains only the file "3.txt". "glob()" will produce the following results. Notice how any leading components of the path are preserved.
>>> import glob >>> glob.glob('./[0-9].*') ['./1.gif', './2.txt'] >>> glob.glob('*.gif') ['1.gif', 'card.gif'] >>> glob.glob('?.gif') ['1.gif'] >>> glob.glob('**/*.txt', recursive=True) ['2.txt', 'sub/3.txt'] >>> glob.glob('./**/', recursive=True) ['./', './sub/']
If the directory contains files starting with "." they won’t be matched by default. For example, consider a directory containing "card.gif" and ".card.gif":
>>> import glob >>> glob.glob('*.gif') ['card.gif'] >>> glob.glob('.c*') ['.card.gif']
