``*``, ``?``, and character ranges expressed with ``[]`` will be correctly
matched. This is done by using the :func:`os.listdir` and
:func:`fnmatch.fnmatch` functions in concert, and not by actually invoking a
subshell. (For tilde and shell variable expansion, use

filenames beginning with a dot (``.``) as special cases. (For tilde and shell

For a literal match, wrap the meta-characters in brackets.
For example, ``'[?]'`` matches the character ``'?'``.

>>> import glob
>>> glob.glob('*.gif')
['card.gif']
>>> glob.glob('.c*')
['.card.gif']
