There's also no need for both headscount and tailscount unless the code allows for a "coin" to land on its edge. 100 - headscount => tailscount >>> TRIALS = 100 >>> import random >>> run = [random.choice([0, 1]) for _ in range(TRIALS)] >>> print "Heads: %s, Tails: %s" % (sum(run), TRIALS - sum(run)) Heads: 51, Tails: 49 >>> >>> TRIALS = 200 >>> run = [random.choice([0, 1]) for _ in range(TRIALS)] >>> print "Heads: %s, Tails: %s" % (sum(run), TRIALS - sum(run)) Heads: 112, Tails: 88 >>> -- Wulfraed Dennis Lee Bieber AF6VN wlfraed@ix.netcom.com HTTP://wlfraed.home.netcom.com/
