13| print("F")

Way Two: Using else statements with suites of nested if/else statements. Once a grade is found,
the program does not execute any other of the conditions. The type of nesting may become confusing
for very complex problems.

29| else:

Way Three: The third solution uses the elif and else clauses to test at each grade point. When the
first condition is found to be true, the other conditions are skipped.
