Is this the "while True" that gave you errors?  I think it
should, since a "while" should be followed by an indented block
of code.  Perhaps you should use this "while True" to replace
the "for x in range(3)" near the bottom.

In future questions, it might help if you explained which of these
print statements you would like to see executed how many times.
