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()}.)
\index{filenames!pathname expansion}
\begin{funcdesc}{glob}{pathname}
Return 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-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).
\end{funcdesc}
\begin{funcdesc}{iglob}{pathname}
Return an iterator which yields the same values as \function{glob()}
without actually storing them all simultaneously.
\versionadded{2.5}
\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.
