# 2.9:  Based on the earlier exercise in which we said THANKS FOR THE INTEGER!, place your whole
# program inside a while True: block.  If the input is all digits (i.e., an integer), include the
# print statement indicating success, and follow it with a break statement to leave the loop.  As
# you know, if you do not break, at the end of the block while's "automatic return" will return to
# the top of the block automatically and your block will take input() again.

# Sample program run:

# please enter an integer:  hello
# that was NOT an integer!
# please enter an integer:  one?
# that was NOT an integer!
# please enter an integer:  5
# THANKS FOR THE INTEGER!
