"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 "'?'".

也參考: 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 *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.

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

   備註: Using the ""**"" pattern in large directory trees may
     consume an inordinate amount of time.

   3.5 版更變: 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'".

   3.4 版新加入.

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']
