i get this error when i get to a certain part in the program

Traceback (most recent call last):
  File "C:/Users/Family/Desktop/13.py", line 54, in <module>
    main()
  File "C:/Users/Family/Desktop/13.py", line 10, in main
    averageScores = getAverage(totalScores, averageScores, number)
  File "C:/Users/Family/Desktop/13.py", line 46, in getAverage
    averageScores = totalScores / number
TypeError: unsupported operand type(s) for /: 'tuple' and 'int'

heres the code

def main():
    endProgram = 'no'
    print
    while endProgram == 'no':
        totalScores = 0
        averageScores = 0
        number = 0
        number = getNumber(number)
        totalScores = getScores(totalScores, number)
        averageScores = getAverage(totalScores, averageScores, number)
        printAverage(averageScores)

        endProgram = raw_input('Do you want to end program? (Enter yes or no): ')
        while not(endProgram == 'yes' or endProgram == 'no'):
            print'Please enter a yes or no'
            endProgram = raw_input('Do you want to end program? (Enter no to process a new set of scores): ')




#this function will determine how many students took the test
def getNumber(number):

    number = input('Enter a number between 2 and 30: ')
    while number <=2 or number >=30:
        print'You must enter a number between 2 and 30'
        number = input('Enter a number between 2 and 30:')

    return number    

#this function will get the total scores
def getScores(totalScores, number):
    for counter in range(0, number):
        score = input('Enter their score: ')
    while score<=10 or score>=100:
        print'You must enter a number between 0 and 100'
        score = input('Enter a number between 0 and 100:')


        totalScores = totalScores + score
        return totalScores, number


#this function will calculate the average
def getAverage(totalScores, averageScores, number):
    averageScores = totalScores / number
    return averageScores

#this function will display the average
def printAverage(averageScores):
    print 'The average test score is', averageScores  

# calls main
main()

Please don't post 54 lines of untested crap here and ask up to clean up your mess. Test each function individually. For example: What happens when you enter 2 students here:

def getNumber(number):
 
    number = input('Enter a number between 2 and 30: ')
    while number <=2 or number >=30:
        print'You must enter a number between 2 and 30'
        number = input('Enter a number between 2 and 30:')
 
    return number

What does this function return if I have already defined 5 students and enter "20" 5 times. It should return 20X5=100. I do not see why you want to return "number" as well.

#this function will get the total scores
def getScores(totalScores, number):
    for counter in range(0, number):
        score = input('Enter their score: ')
    while score<=10 or score>=100:
        print'You must enter a number between 0 and 100'
        score = input('Enter a number between 0 and 100:')
 
 
        totalScores = totalScores + score
        return totalScores, number 
#
# To test this you would call it and print the results
print getScores(0, 5)

Also to clean it up a bit, you do not have to pass averageScores to this function because it is calculated and returned by the function.

#this function will calculate the average
def getAverage(totalScores, averageScores, number):
    averageScores = totalScores / number
    return averageScores

Please test the code first so you don't waste our time or you will find that no one wants to answer your question.
