!glob --- Unix style pathname pattern expansion.. module:: glob :synopsis: Unix shell style pathname pattern expansion.
Source code: :source:Lib/glob.py
.. index:: single: filenames; pathname expansion
.. index:: single: * (asterisk); in glob-style wildcards single: ? (question mark); in glob-style wildcards single: [] (square brackets); in glob-style wildcards single: ! (exclamation); in glob-style wildcards single: - (minus); in glob-style wildcards single: . (dot); in glob-style wildcards
The :mod:!glob module finds pathnames
using pattern matching rules similar to the Unix shell.
No tilde expansion is done, but *, ?, and character
ranges expressed with [] will be correctly matched. This is done by using
the :func:os.scandir and :func:fnmatch.fnmatch functions in concert, and
not by actually invoking a subshell.
.. note:: The pathnames are returned in no particular order. If you need a specific order, sort the results.
Files beginning with a dot (.) can only be matched by
patterns that also start with a dot,
unlike :func:fnmatch.fnmatch or :func:pathlib.Path.glob.
For tilde and shell variable expansion, use :func:os.path.expanduser and
:func:os.path.expandvars.
For a literal match, wrap the meta-characters in brackets.
For example, '[?]' matches the character '?'.
The :mod:!glob module defines the following functions:
.. function:: glob(pathname, *, root_dir=None, dir_fd=None, recursive=False,
include_hidden=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 :file:/usr/src/Python-1.5/Makefile) or relative (like
:file:../../Tools/\*/\*.gif), and can contain shell-style wildcards. Broken
symlinks are included in the results (as in the shell). Whether or not the
results are sorted depends on the file system. If a file that satisfies
conditions is removed or added during the call of this function, whether
a path name for that file will be included is unspecified.
If root_dir is not None, it should be a :term:path-like object
specifying the root directory for searching. It has the same effect on
:func:!glob as changing the current directory before calling it. If
pathname is relative, the result will contain paths relative to
root_dir.
This function can support :ref:paths relative to directory descriptors <dir_fd> with the dir_fd parameter.
.. index:: single: **; in glob-style wildcards
If recursive is true, the pattern "**" will match any files and zero or
more directories, subdirectories and symbolic links to directories. If the
pattern is followed by an :data:os.sep or :data:os.altsep then files will not
match.
If include_hidden is true, "**" pattern will match hidden directories.
.. audit-event:: glob.glob pathname,recursive glob.glob .. audit-event:: glob.glob/2 pathname,recursive,root_dir,dir_fd glob.glob
.. note::
Using the "**" pattern in large directory trees may consume
an inordinate amount of time.
.. note::
This function may return duplicate path names if pathname
contains multiple "**" patterns and recursive is true.
.. versionchanged:: 3.5
Support for recursive globs using "**".
.. versionchanged:: 3.10 Added the root_dir and dir_fd parameters.
.. versionchanged:: 3.11 Added the include_hidden parameter.
.. function:: iglob(pathname, *, root_dir=None, dir_fd=None, recursive=False,
include_hidden=False)
Return an :term:iterator which yields the same values as :func:glob
without actually storing them all simultaneously.
.. audit-event:: glob.glob pathname,recursive glob.iglob .. audit-event:: glob.glob/2 pathname,recursive,root_dir,dir_fd glob.iglob
.. note::
This function may return duplicate path names if pathname
contains multiple "**" patterns and recursive is true.
.. versionchanged:: 3.5
Support for recursive globs using "**".
.. versionchanged:: 3.10 Added the root_dir and dir_fd parameters.
.. versionchanged:: 3.11 Added the include_hidden parameter.
.. function:: 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'.
.. versionadded:: 3.4
.. function:: translate(pathname, *, recursive=False, include_hidden=False, seps=None)
Convert the given path specification to a regular expression for use with
:func:re.match. The path specification can contain shell-style wildcards.
For example:
>>> import glob, re
>>>
>>> regex = glob.translate('**/*.txt', recursive=True, include_hidden=True)
>>> regex
'(?s:(?:.+/)?[^/]*\\.txt)\\z'
>>> reobj = re.compile(regex)
>>> reobj.match('foo/bar/baz.txt')
<re.Match object; span=(0, 15), match='foo/bar/baz.txt'>
Path separators and segments are meaningful to this function, unlike
:func:fnmatch.translate. By default wildcards do not match path
separators, and * pattern segments match precisely one path segment.
If recursive is true, the pattern segment "**" will match any number
of path segments.
If include_hidden is true, wildcards can match path segments that start
with a dot (.).
A sequence of path separators may be supplied to the seps argument. If
not given, :data:os.sep and :data:~os.altsep (if available) are used.

:meth:`pathlib.PurePath.full_match` and :meth:`pathlib.Path.glob`
methods, which call this function to implement pattern matching and
globbing.
.. versionadded:: 3.13
Consider a directory containing the following files:
:file:1.gif, :file:2.txt, :file:card.gif and a subdirectory :file:sub
which contains only the file :file:3.txt. :func: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 :file:card.gif and
:file:.card.gif::
import glob glob.glob('.gif') ['card.gif'] glob.glob('.c') ['.card.gif']
