Write a program that asks the user to enter 5 test scores. Theprogram will display a letter grade for each test score and anaverage grade for the test scores entered. The program will writethe student name and average test score to a text file(“studentgrades.txt”). Three functions are needed for thisprogram.
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 asum
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 testscore
Answer:
Code Screenshot:
ExecutableCode:
#Function to find the letter gradedef 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 averagedef calculate_average_grade(test1, test2, test3, test4,test5): sum= test1+test2+test3+test4+test5 #Calculate average average = sum/5 #Return result return average
#Main Functiondef main(): #Declaring the requiredvariables 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 fortest 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 andlettergrade to file f.write(name) f.write(“\nAverage Test Score=”+str(average)) f.write(“\nLetter Grade=”+str(letter_grade(test_score)))
