#
# Summary of Best Proctices
# 1. Put code that takes a long time to run or has other effects
#    on the computer in a function or class, so you can control
#    exactly when that code is executed
# 2. Use the different values of __name__ to determine the context
#    and change the behavior of your code with conditional
#    statements
# 3. Name the entry point function main() in order to communicate
#    the intention of the function, even though Python does not
#    assign any significance to a function names main()
# 4. If you want to reuse functionallity from your code, define
#    the logic in functions outside main() and call thoes function
#    within main()
