编写一个函数对一个数进行平方，然后用它来编写一个函数，该函数接受三个整数并返回它们的平方和

Question

Im new to python and cant figure out how to get these functions to call themselves. It asks for an input but no matter what gives 0 as the output. Can someone help debug?

userinput = input("Enter three numbers: ")
userinput = userinput.split(',')
finalsum = 0
finaldata = []

def formatinput(x):
 sqrdata = []
  for element in x:    
    sqrdata.append(int(element))
  return(sqrdata)

def findsquare(x):
 return (x*x) 

def sumthesquares(y):
  for element in y:
    temp = findsquare(element)
    finaldata.append(int(temp))
    finalsum = finalsum + temp
  return finalsum

def findthesquares(userinput):
  finalsum = sumthesquares(formatinput(userinput))

print(finalsum)

Answer 1

Have you actually tried running your code? From what you've posted, it looks like you never actually call your functions...

They're defined, but you're missing the actual calls, like formatinput(userinput) .

For future reference, if you put something like print("Got here!") into your functions, you can test that they're being called.
