Need Help! Asap 7.5 code practice (Edhesive)

def GPAcalc(g, w):

   if g == "a" or g == "A":

       return 4 + w

   elif g == "B" or g == "b":

       return 3 + w

   elif g == "C" or g == "c":

       return 2 + w

   elif g == "D" or g == "d":

       return 1 + w

   elif g == "F" or g == "f":

       return 0 + w

   else:

       return "Invalid"

def GPAAV(S, C):

   return S/C

Sum = 0

Classes = int(input("How many Classes are you taking? "))

for i in range(0, Classes):

   Grade = (input("Enter your Letter Grade: "))

   Weight = int(input("Is it weighted? (1= yes) "))

   gpa = GPAcalc(Grade, Weight)

   print("Your GPA score is: " + str(gpa))

   Sum = Sum + gpa

print("Your weighted GPA is a " + str(GPAAV(Sum, Classes)) + ".")

Explanation:

This one should work, let me know in the comments.

Make main function

def main():

Make some constants for the grades

A = 5.0 or 4.0

B = 4.0 or 3.0

C = 3.0 or 2.0

D = 2.0 or 1.0

F = 1.0 or 0.0

In the main function call the function you made and make sure to use those constants for help

also don't forget to call your main function or nothing will work

Explanation:

Making the main function is good programming practice for your future

Making the constants is also helpful to your programming.

Now how it works you call the function you wrote to calculate the grade.

I don't know how helpful this was this is one of my first answers. I am `also answering how I would do it

answer; i believe its aptitude;
