Note, while the dupe target says nothing about that specific NameError, the NameError is only the most direct symptom of the underlying problem, which is that Python 3 dropped the old 3-way comparisons entirely. `cmp` was a part of the removed system. – user2357112 Oct 25 '22 at 08:26

There are potentially other problems in using Python 2 code in Python 3. You could perhaps run the code through a Python 2 to Python 3 conversion utility. – John Coleman Oct 25 '22 at 10:50
