Flow Control 1: for, for-else

# Simple for loop example.
for i in range(0,11):
        print "The value of i is %d." % i

# for-else example.
# This is taken directly from the Python documentation. The else statement
# looks as though it's in the wrong place. It's not. Python for loops can have
# else statements.
