flip never changes again it's not reassigned in the while loop > heads += 1 > > else: > tails += 1 > > > count += 1 > > > > print "The coin landed on heads", heads, 'times ' \ > "and tails", tails, 'times' > in case you know how many times to iterate it's better to use for loop (in python and eq C also) from random import randrange as flip result = [0,0] for i in range(100): result[flip(2)] += 1 or from random import randrange as flip result = {"head":0, "tail":0} for i in range(100): result[["head","tail"]flip(2)] += 1 or >>> class Coin: ... def flip(self): ... import random ... return ("head", "tail")[random.randrange(2)] c = Coin() result = {"head":0,"tail":0} for i in range(100): result[c.flip()] += 1 or many many more the important thing is .. to know what is the most suitable data representation for you is it throw-away-code or is this going to be read by other people .. etc hth, Daniel -- http://mail.python.org/mailman/listinfo/python-list
