Hello, I'm looking for a way to find the occurrences of x is y comparisons in an existing code base. Except for a few special cases (e.g. x is [not] None) they're a usually mistakes, the correct test being x == y. However they happen to work most of the time on CPython (e.g. when y is a small integer or string) so they slip into production code unnoticed.
PyLint and PyFlakes don't check this AFAICT. Any suggestions for such a tool, or a pointer how to add the check to an existing tool would be most welcome. Regards, Alex -- http://mail.python.org/mailman/listinfo/python-list
