I don't think so. People do try to use assignment in expressions, even if only by mistake writing = when they meant == and need to distinguish between them. In Python 2, the most common clash between statements and expressions was print, but at least that's gone. https://www.quora.com/Whats-the-difference-between-a-statement-and-an-expression-in-Python-Why-is-print-%E2%80%98hi%E2%80%99-a-statement-while-other-functions-are-expressions https://stackoverflow.com/questions/4728073/what-is-the-difference-between-an-expression-and-a-statement-in-python https://stackoverflow.com/questions/43435850/what-is-the-difference-between-a-statement-and-a-function-in-python Even without assignment expressions, people still need to know why they can't write "if mo = re.match(pattern, text)". > again, not a huge deal, just a little bit more complexity Every new feature is added complexity. -- Steve _______________________________________________ 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
