Python sets comparisons

Read Original

The article details a technical investigation into an unexpected behavior in Python 2.7 where sets containing objects with a custom __eq__ method that always returns True could fail equality checks. It contrasts this with Python 3's behavior, which raises a TypeError for unhashable types, and explains the solution of implementing a proper __hash__ method.
