Python: How do I add a “Final Grade” converter in my Grading System Calculator

Not really sure what your question is, but here is a more succinct way of getting the letter grade.

>>> scores = [93, 89, 87, 83, 79, 77, 73, 69, 67, 60, 0]
>>> grades = [A, A-, B+, B, B-, C+, C, C-, D+, D, F]
>>> 
>>> def gradeFor(s):
...     grade_scores = zip(scores, grades)
...     for score, grade in grade_scores:
...        if s >= score:
...            return grade

>>> gradeFor(87)
B+
>>> gradeFor(89)
A-
>>> gradeFor(88)
B+
>>> gradeFor(67)
D+
>>> gradeFor(72)
C-
>>> gradeFor(40)
F

Also, you can do

if endProgram.lower() in (no, false):
