The function is an illustration of for loops

For loops are used to perform repetitive operations; just like the while loop

The program in Python, where comments are used to explain each line is as follows:

#This defines the studentGPA function

def studentGPA(grade, weight):

   #This initializes a dictionary for all grades

   allGrade = {"A": 4, "B": 3, "C": 2, "D": 1, "F": 0}

   #This sets the return grade to 0

   retValue = 0

   #If the grade is valid

   if grade in allGrade:

       #If the weight is 0

       if weight == 0:

           #Then score is not graded

           retValue = allGrade[grade]

       #If otherwise

       else:

           #This adds 1 to the return grade

           retValue = allGrade[grade]+1

   #This returns the grade point

   return retValue

#The main begins here    

#This gets the number of classes

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

#This initializes the total grade to 0

total = 0

#This following is repeated for each class

for x in range(klass):

   #This gets input for the letter grade

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

   #This gets input for the weight

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

   #This gets the corresponding grade

   grade = studentGPA(letterGrade, weight)

   #This prints the grade point

   print("Your GPA score is: ", grade)

   #This calculates the total grade

   total += grade

#This calculates the GPA

GPA = total/klass

#This prints the GPA

print("Your weighted GPA is a",GPA)

def calculate_GPA(grade, weight):

   grades = {"A": 4, "B": 3, "C": 2, "D": 1, "F": 0}

   if weight == 0:

       return grades[grade]

   else:

       return grades[grade] + 1

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

total = 0

for x in range(classes):

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

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

   grade = calculate_GPA(letter, user_weight)

   total += grade

   print("Your GPA score is: ", grade)

print("Your weighted GPA is a",(total/classes))

I wrote my code in python 3.8. I was able to replicate the output in your picture exactly. If you need me to make any changes, I'll do my best.
