Add a function to determine the letter grade A B C D or F of

Add a function to determine the letter grade (\'A\', \'B\', \'C\', \'D\'; or \'F\') of one exam score. Create and use named constants for each of the point cutoffs (90 for an A, 80 for a B, 72 for a C, 62 for a D). Refer to the top four lines of the sample output below. Display the letter grade (inside parentheses) next to each score by calling your new function for each exam score. Add a function to determine the largest of the three exam scores. Refer to the bottom line of the sample output below. Display the highest score below the other results. Test your project and check your results. Show your project output and code. Sample output: Student Name: Cindy Exam #1: 90 (A) Exam #2: 98 (A) Exam #3: 85 (B) Highest score: 98 data: Amy 90 98 85 Melanie 80 89 90 Bob 62 55 76 Timothy 80 79 72

Solution

dict = {90:\"A\",80:\"B\",72:\"C\",62:\"D\"}
def get_max(list):
return max(list)
def grade(score):
for i in dict:
if(score>=i):
return dict[i]
file = open(\"scores.txt\",\"r\")
data = file.read().split(\"\ \")
for line in data:
stud = line.split(\" \")
scores = map(int,stud[1:])
print \"Student Name:\"+stud[0]
print \"Exam #1:\",scores[0],grade(scores[0])
print \"Exam #2:\",scores[1],grade(scores[1])
print \"Exam #3:\",scores[2],grade(scores[2])
print \"Highest score:\",get_max(scores)
