    This example is misleading. The comment in the function states that it takes checksums of each file, but the function itself only takes checksums of the file paths found in a directory not their contents.

    Here is a small modification that will also make the output compatible with 'sha1sum -c' :-

    filepath = os.path.join(root, name)
value = sha.new(open(filepath, 'rb').read()).hexdigest()
print value, '*%s' % filepath

    I made a more robust version of the previous commenters code if anyone reading this is interested:
