Python makes assignment a full top level type of statement, so = can't be misused in an expression thinking it means an equality test (and then added recently the := operator, so that for the cases you actually want to do assignments in the middle of an expression you can). -- Richard Damon -- https://mail.python.org/mailman/listinfo/python-list
