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)
