Also, with the functional programming tools of map, filter, and lambda, 
this code can be reduced to just six lines:

import random

flips = map(lambda x: random.randrange(2), xrange(100))
heads = len(filter(lambda x: x is 0, flips))
tails = len(filter(lambda x: x is not 0, flips))

print "The coin landed on heads", heads, "times."
print "The coin landed on tails", tails, "times."
