function - Make a Program in Python that calculates the student's GPA?

Question

I am in need of assistance on a coding question in Python.

I have to calculate a student’s GPA. The program must ask them how many classes they are taking, then ask them to enter the grades for each class and if it is weighted.

The program should then output the averaged GPA including the decimal place, and my main program must call the function.

The question gives a chart for the non-weighted and weighted number scores that correlates with the given letter grade: gpa chart

Here's what I have so far:

def average (c): 
    div = c
    avg =(1.0*(sum(scores))/div)

#****************MAIN********************
c = input("How many classes are you taking?")
print ("You are taking " + str(c) + " classes.") 
x = input("Enter your letter grade.") 
w = int(input("Is it weighted? (1 = yes)")
    while (c <= 7): #Here it is saying that there is a syntax error because I input a while loop. I don't know why it is saying this. 
    if (x == A): 
        if (w == 1): 
            print ("Your GPA score is 5")
        else: 
            print ("Your GPA score is 4")
    elif (x == B): 
        if (w == 1): 
            print ("Your GPA score is 4")
        else: 
            print ("Your GPA score is 3") 

    elif (x == C): 
        if (w == 1): 
            print ("Your GPA score is 3")
        else: 
            print ("Your GPA score is 2") 

    elif (x == D): 
        if (w == 1): 
            print ("Your GPA score is 2") 
        else: 
            print ("Your GPA score is 1") 

    elif (x == F): 
        if ( w == 1): 
            print ("Your GPA score is 1")      
        else: 
            print ("Your GPA score is 0") 

    scores = []
    list.append(x)

    average(c)

Any help would be much appreciated! :)

Not sure about what you are asking for, but fixing just after the function definitions might be a good start

Don't

def classes(c): 
print ("You are taking " + c  + " classes.") 

Do

def classes(c): 
    print ("You are taking " + c  + " classes.")
