This line is you logic error because it's not part of your while loop
the coin variables get the result of random.randrange(2) assigned only
one time (before the loop).

You could changed the program to this it works too and is just as
readable (IMHO):
#Coin flipper
import random
heads = 0
tails = 0
counter = 0
# removed random line
while (counter < 100):
if random.randrange(2): # put random here
heads += 1
counter += 1
else:
tails += 1
counter += 1
# removed random line
print "\nThe coin landed on heads", heads, "times."
print "\nThe coin landed on tails", tails, "times."
Take my advice with caution I'm also new to this :-)
Btw, it is possible that the coins lands on it side if not catched with
the hand (yes I have seen it happen) ;-)
