XKCD inspired me to write a quick Collatz Conjecture script in Python

collatz.py

import random

def main():
    start = n = round(random.random() * 100000)
    i = 0

    while not n == 1:
        i += 1
        if n % 2:
            # The remainder isn't zero, so this evaluates to True
            old = n
            n = n * 3 + 1
            print "Odd: %i * 3 + 1 = %i" % (old, n)
        else:
            # The remainder is zero, so this evaluates to False
            old = n
            n = n / 2
            print "Even: %i / 2 = %i" % (old, n)

    print "The number %i was converged to 1 in %i steps." % (start, i)

if __name__ = 'main':
    main()
