Grade Conversion

COMP 1010 Home > Back to Extra Labs

Introduction Create a program that converts a numerical grade to its corresponding letter grade. The letter grades that need assigning are (Please note that the following ranges are inclusive): A : 80-100 (Excellent work) B: 70-79 (Very Good) C: 60-69 (Average) D: 50-59 (Below Average) F: 0-49 (Below Average) Prompt the user to input a letter grade (between 0 and 100). Output the letter grade and a brief grade description (such as "Excellent work"). Use raw_input and print for output. Ensure that necessary validity checks are done in the program to prevent invalid (numerical) input. Use constants for the letter grade ranges. .

Step 1: Get inputs/outputs needed to solve the problem

input - Used to prompt the user for input

mark - The mark that is to be used for the computation

Step 2: Write the program

# This program is used to convert
# a mark into its approparite 
# letter grade

## Get mark from the user
mark = input("Please enter your marks:")

if (mark >= 75):
    print "Your grade is above average"
elif (mark >= 70):
    print "Your grade is average"
elif (mark <= 65):
    print "Your grade is below average"
else:
    print "This is not a valid mark. Please input another mark." 

Step 3: Contrast with Letter Grade Conversion program in Program-A-Day example

This Python program produces exactly the same result as the Java Letter Grade Conversion program in Program-A-Day.
