Hi folks, I'm new to Python, I'm working my way through some intro books, and I have a question that I wonder if someone could help me with please?
This is my attempt at solving an exercise where the program is supposed to flip a coin 100 times and then tell you the number of heads and tails. ATTEMPT 1 returns: The coin landed on tails 100 times The coin landed on heads 0 times ATTEMPT 2 returns: The coin landed on tails 75 times The coin landed on heads 25 times I expected to see the result in attempt 2. I don't fully understand why the results are different however. Is it because Python only runs the randint function once when I call it by the name I assigned to it in attempt 1, but it runs the function fully on each iteration of the loop in attempt 2? Why are these two things different? Thanks in advance, Chris ------------------------------------------------------------------ ATTEMPT 1 ------------------------------------------------------------------ import random heads = 0 tails = 0 tossNo = 0 toss = random.randint(1,2) while tossNo <= 99: if toss == 1: heads += 1 tossNo += 1 elif toss == 2: tails += 1 tossNo += 1 print "The coin landed on tails " + str(tails) + " times \n" print "The coin landed on heads " + str(heads) + " times \n" ------------------------------------------------------------------ ATTEMPT 2 ------------------------------------------------------------------ import random heads = 0 tails = 0 tossNo = 0 while tossNo <= 99: if random.randint(1,2) == 1: heads += 1 tossNo += 1 elif random.randint(1,2) == 2: tails += 1 tossNo += 1 print "The coin landed on tails " + str(tails) + " times \n" print "The coin landed on heads " + str(heads) + " times \n" _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
