:mod:`glob` --- Unix style pathname pattern expansion
|
|
=====================================================
|
|
|
|
.. module:: glob
|
|
:synopsis: Unix shell style pathname pattern expansion.
|
|
|
|
|
|
.. index:: single: filenames; pathname expansion
|
|
|
|
**Source code:** :source:`Lib/glob.py`
|
|
|
|
--------------
|
|
|
|
The :mod:`glob` module finds all the pathnames matching a specified pattern
|
|
according to the rules used by 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.listdir` and
|
|
:func:`fnmatch.fnmatch` functions in concert, and not by actually invoking a
|
|
subshell. Note that unlike :func:`fnmatch.fnmatch`, :mod:`glob` treats
|
|
filenames beginning with a dot (``.``) as special cases. (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 ``'?'``.
|
|
|
|
|
|
.. function:: glob(pathname)
|
|
|
|
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).
|
|
|
|
|
|
.. function:: iglob(pathname)
|
|
|
|
Return an :term:`iterator` which yields the same values as :func:`glob`
|
|
without actually storing them all simultaneously.
|
|
|
|
|
|
For example, consider a directory containing only the following files:
|
|
:file:`1.gif`, :file:`2.txt`, and :file:`card.gif`. :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']
|
|
|
|
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']
