\section{Standard Module \module{glob}}
|
|
\label{module-glob}
|
|
\stmodindex{glob}
|
|
|
|
The \module{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 \code{*}, \code{?}, and character ranges
|
|
expressed with \code{[]} will be correctly matched. This is done by
|
|
using the \function{os.listdir()} and \function{fnmatch.fnmatch()}
|
|
functions in concert, and not by actually invoking a subshell. (For
|
|
tilde and shell variable expansion, use \function{os.path.expanduser()}
|
|
and \function{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/Python\version/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}. \function{glob()}
|
|
will produce the following results. Notice how any leading components
|
|
of the path are preserved.
|
|
|
|
\begin{verbatim}
|
|
>>> import glob
|
|
>>> glob.glob('./[0-9].*')
|
|
['./1.gif', './2.txt']
|
|
>>> glob.glob('*.gif')
|
|
['1.gif', 'card.gif']
|
|
>>> glob.glob('?.gif')
|
|
['1.gif']
|
|
\end{verbatim}
