As a statement in a program (as opposed to typed at a shell), "a := 3" has the unnecessary (in that context) property of returning (and discarding 3), so it's better style to use "a = 3" in that context.

If := were the one and only assignment symbol, the compiler could easily optimise away the extra DUP_TOP or whatever is involved. -- Greg _______________________________________________ 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
