http://pychecker.sourceforge.net/

This is one of the many types of errors that PyChecker checks for.

Once my Python source is more than 3 screens long, I run PyChecker on
it regularly.

Frankly, I like Python's permissiveness and PyChecker's fussiness.
For me I code correct code faster with this pair than with languages
that force declaration of identifiers before use.
