# Sometimes if you are going to be using and reusing small bits of Python code
# over and over again, you might want to consider using the 'exec()' function.
# The 'exec()' function can be used in such examples as these examples below.

# Here is an example, using a for-loop to call the 'exec()' function.

for i in range(3):
    exec(redundant_code)

# Let's create a for loop inside an exec() function and see what happens when
# execute/run this Python program example:
