CIMP 8A

Code Lab 4

Write a program that asks the user to enter 5 test scores. The program will display a letter grade for each test score and an average grade for the test scores entered. The program will write the student name and average test score to a text file (“studentgrades.txt”). Three functions are needed for this program.

def letter_grade( test_score)

Test Score	Letter Grade
90-100	A
80-89	B
70-79	C
60-69	D
Below 60	F

return letter grade

def calculate_average_grade( test1, test2, test3, test4, test5)

add 5 test scores together with a sum

divide the sum by 5 for an average

return the average

def main() Starting function

            In a loop for 4 students

Enter student name

                        In a loop for 5 test scores

enter test score

                                    call letter_grade(test_score)

                                    display testscore and letter grade

                        After loop

                                    call calculate_average_grade (test1, test2, test3, test4, test5)

                                    display average test score

                                    write to output file –

                                                            name,

average test score and

letter grade for average test score

Executable Code:

#Function to find the letter grade
def letter_grade(test_score):
   if test_score <=100 and test_score>=90:
       return 'A'
   if test_score <=89 and test_score>=80:
       return 'B'
   if test_score <=79 and test_score>=70:
       return 'C'
   if test_score <=69 and test_score>=60:
       return 'D'
   if test_score <60:
       return 'F'

#Function to calculate the average
def calculate_average_grade(test1, test2, test3, test4, test5):
   sum= test1+test2+test3+test4+test5
   #Calculate average
   average = sum/5
   #Return result
   return average

#Main Function
def main():
   #Declaring the required variables
   test1=0
   test2=0
   test3=0
   test4=0
   test5=0
   #Prompting the user for name
   name = input("Please enter your name: ")
   for i in range(5):
       #Prompting the user for test scores
       test_score = int(input("Enter test "+str(i+1)+" score: "))
       print("Test Score :",test_score,"Letter Grade:",letter_grade(test_score))
       if i==0:
           test1=test_score
       elif i==1:
           test2=test_score
       elif i==2:
           test3=test_score
       elif i==3:
           test4=test_score
       elif i==4:
           test5=test_score
   #Find the average
   average = calculate_average_grade(test1, test2, test3, test4, test5)
   #Display the average
   print("Average: ",average)
   #Open file
   with open("studentgrades.txt","w") as f:
       #Write name average and lettergrade to file
       f.write(name)
       f.write("\nAverage Test Score ="+str(average))
       f.write("\nLetter Grade ="+str(letter_grade(test_score)))

#Function call to main
main()
