Personally I would have like to see  := replace = as the assignment operator.  No more confusing = with ==, and as a replacement rather than an addition no confusion as to when to use = or :=<br>On the other hand Python was originally developed to teach non programmers to program, so to add := as an additional assignment operator does add complexity which non programmers probably don't want/need.  Of course if := replaced = then that issue would be removed.
