Question

Using python code

Developed a program to get students homework, midterm, and final exam grades and compute their average grades display average grade as a number and give them letter gardes. For this homework, I would like you to modify your to do the following.

Student grades MUST be between 0 and 100. If students input any number that is not in this range , program must keep asking to enter the correct number. Once student input correct grade, program should move on to next grade.

For example if a student had an average grade of 90, and student name is Alex Smith, the course code is CSCI1012, the program must display:

Student Name: Alex Student Last name : Smith Course: CSCI1012 Student Average grade: 90 Student final grade : A

Answer 1

Code: --

first=input('enter your first name: ') #taking input from user for firstand last name and course name
last=input('enter your last name: ')
course=input('enter your course name: ')
while True:# take input valid marks
    ho=input('enter homework marks out of 100 : ')
    if not ho.isdecimal() or int(ho)<0 or int(ho)>100: # validate marks if not in 100 then retake
        print('enter valid marks : ')
        continue
    else: # if valid then go for next mark
        break

while True:
    mid=input('enter mid marks out of 100 : ') # validate marks if not in 100 then retake
    if not mid.isdecimal() or int(mid)<0 or int(mid)>100:
        print('enter valid marks : ')
        continue
    else: # if valid then go for next mark
        break
while True:
    fin=input('enter final marks out of 100 : ')# validate marks if not in 100 then retake
    if not fin.isdecimal() or int(fin)<0 or int(fin)>100:
        print('enter valid marks : ')
        continue
    else: # if valid then go for next mark
        break
avr=((int(ho)+int(mid)+int(fin))/3) # calculating avr marks
# printing studnet details
print("Student's first name:", first)
print("Student's last name:", last)
print("Course name:", course)
print("Average grade:",avr)

# printing gread according to avrage marks
if avr<101 and avr>90:
    print("Student final grade : A")
elif avr<91 and avr>80:
    print("Student final grade : B")
elif avr<81 and avr>70:
    print("Student final grade : C")  
elif avr<71 and avr>60:
    print("Student final grade : D")  
else :
    print("Student final grade : E")
