OK, this is the best explanation I've seen for the code I'm talking about. This code may be found at: http://norvig.com/sudo.py in the definition of the function eliminate. Here's the fragment: elif len(values[s]) == 1: ## If there is only one value (d2) left in square, remove it from peers d2, = values[s] Now, in the assignment, values[s] *is* a string of length 1. So this assignment appears to me entirely equivalent (in its ultimate effect) to the more straightforward d2 = values[s] ...but, since I'm a noob, I thought I'd ask :-) Thanks! kynn -- NOTE: In my address everything before the first period is backwards; and the last period, and everything after it, should be discarded. -- http://mail.python.org/mailman/listinfo/python-list
