Hum, maybe I wasn't specific enough. I'm looking for "for loops" and list comprehensions in stdlib which *can be* written using assignment expression, like: [var for ... in ... if (var := expr)]. I'm not discussing if such change is worth it or not. I just counted how many for loops/list comprehensions *can* be modified to use assingment expressions in the stdlib. Maybe I missed some loops/comprehensions, and I would be happy to see more examples ;-) Victor _______________________________________________ Python-Dev mailing list Python-Dev@python.org https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
