If you see the historical absence of an assignment operator in Python as a mistake, then the introduction of := is a fix for the mistake that only happened because people kept complaining.
That's not quite the same thing. There was no a PEP saying that there would never be assignment expressions in Python, so there was room for useful debate. Now that the := PEP is accepted, further argument about it is not productive. As far as I know, no PEP has ever been revoked after acceptance, and that's a good thing for the stability of the language. It's like the rule sports usually have that the referee's decision is final, even if it turns out to be wrong. At some point you need to make a decision and move on. -- Greg -- https://mail.python.org/mailman/listinfo/python-list
