"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()".)

对于字面值匹配，请将原字符用方括号括起来。 例如，"'[?]'" 将匹配字符
"'?'"。

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, subdirectories and symbolic links to
   directories. If the pattern is followed by an "os.sep" or
   "os.altsep" then files will not match.

   注解: 在一个较大的目录树中使用 ""**"" 模式可能会消耗非常多的时间
     。

   在 3.5 版更改: 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'".

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']
