"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 files beginning with a dot (".") can only be matched by
patterns that also start with a dot, unlike "fnmatch.fnmatch()" or
"pathlib.Path.glob()". (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). 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
   be included is unspecified.

   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 "os.sep" or
   "os.altsep" then files will not match.

   Raises an auditing event "glob.glob" with arguments "pathname",
   "recursive".

   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.

   Raises an auditing event "glob.glob" with arguments "pathname",
   "recursive".

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']
