|
The \code{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 \verb\*\, \verb\?\, and character ranges
|
||
|
|
expressed with \verb\[]\ will be correctly matched. This is done by
|
||
|
|
using the \code{os.listdir()} and \code{fnmatch.fnmatch()} functions
|
||
|
|
in concert, and not by actually invoking a subshell. (For tilde and
|
||
|
|
shell variable expansion, use \code{os.path.expanduser(}) and
|
||
|
|
\code{os.path.expandvars()}.)
|
||
|
|
|
||
|
|
\begin{funcdesc}{glob}{pathname}
|
||
|
|
Returns a possibly-empty list of path names that match \var{pathname},
|
||
|
|
which must be a string containing a path specification.
|
||
|
|
\var{pathname} can be either absolute (like
|
||
|
|
\file{/usr/src/Python1.4/Makefile}) or relative (like
|
||
|
|
\file{../../Tools/*.gif}), and can contain shell-style wildcards.
|
||
|
|
\end{funcdesc}
|
||
|
|
|
||
|
|
For example, consider a directory containing only the following files:
|
||
|
|
\file{1.gif}, \file{2.txt}, and \file{card.gif}. \code{glob.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']
