# Extra credit
# 1.a. elif means "else if" - if the previous "if" statement is False, python checks if this elif statement is True. If it is, the code block under it will be evaluated.
# 1.b. else means "else" - if the previious "if (or elif)" statement is False, python evaluates the code block under the "else" statement
