It doesn't run because it if full of errors, which have already been discussed by others.

I just wanted to show you a (radically) different approach that you can study (or not... your 
choice).  I'm leaving out your heading and just showing the heart of the program.  I am not 
necessarily recommending this, I just wanted you to see a different way of looking at the 
problem.  Except for the initialization and printing of the results, the entire thing is done in 
one two-line for loop.

<code>
from random import randint

#  Put your heading text here...

HEADS = 0
TAILS = 1    #  Note:  Python _convention_ is to upper-case constants.
counts = [0, 0]

for flips in range(100):
     counts[randint(0, 1)] += 1

print('Number of heads: ', counts[HEADS])
print('Number of tails: ', counts[TAILS])
</code>

Note that the HEADS and TAILS constants are only used in one place (the final print functions), 
you could simply leave them out and directly use 0 and 1 in those final print()s.
