(Obsolete, Only in 1.5.2) The cmpcache module contains a function that compares two files. It’s an extension of the cmp module in that it keeps a cache over recently made comparisons. Example 14-20 shows the module’s use.

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In Python 2.0 and later, this module has been replaced by the filecmp module.
