First, instantiate z=zipfile.ZipFile('whatever.zip').  Now, z.namelist()
gives you a list of all the names in 'whatever.zip', and for each of
these names z.read(name) gives you all the bytes.  Net of subdirectory
issues, therefore, something like (note: untested!):

for n in z.namelist():
    open(n, 'w').write(z.read(n))

should extract all files to the current directory.
