Specification: Using Python3 write a program that prompts the user for a score, convert it into an integer and print the letter grade for that score in this course.

You should use a single if statement for this assignment.

Your if statement should not print anything, but should set a variable that is used in a final print statement at the end of the program.

Add comments in your code.

Use the following grading criteria:

A	> 100 - 93
A -	92 - 90
B +	89 - 86
B	85 - 83
B -	82 - 80
C +	79 - 76
C	75 - 73
C -	72 - 70
D +	69 - 66
D	65 - 63
D -	62 - 60
F	< 60
