The cmpcache module

(Obsolete, only in 1.5.2). This module contains a function to compare two files. It’s an extension of the cmp module, in that it keeps a cache over recently made comparisons.

# File: cmpcache-example-1.py

import cmpcache

if cmpcache.cmp("samples/sample.au", "samples/sample.wav"):
    print "files are identical"
else:
    print "files differ!"

files differ!

In Python 2.0 and later, this module has been replaced by the filecmp module.
