python - Answer prints 0 not actual answer - 


def difference1():     answer = 0     in range(1, 100):         sum1 = a**2         sum1 += answer     print(answer) difference1()

why code printing 0? want numbers between 1 , 100's squares added together. have made dumb mistake can't figure out.

you never change 'answer' varaible, thats why 0 assigned it.

do this:

def difference1():     answer = 0     in range(1, 100):         sum1 = a**2         answer += sum1 #the change on line     print(answer) difference1()
