Not quite. Wildcard expansion (which the * is all about) is done by
the shell on unixoid operating systems such as BSD and Linux, but not
by the MS-DOS command line. You have the following options:

a) Try using a port of a unix shell on windows. For example, cygwin
(see http://www.cygwin.com/) is quite usable. If you run that sample
in a cygwin bash shell on windows, it'll work

b) Expand it yourself, e.g. using

import os, fnmatch

def expand_wildcards(pattern):
    # get name of directory without wildcards
    dirname = os.path.dirname(pattern)

    # get name of pattern
    pattern = os.path.basename(pattern)

    # list all files
    return fnmatch.filter( os.listdir(dirname), pattern )
