在 Python 中使用另一个函数的返回输出

Question

new to Python - struggling with functions. - Image of code attached.

It inputs the name & scores just fine with the validation checks. I need to use the scores input by the user and total them. However, when I've tried to sum(score) it doesn't like it. I can't work out how to sum the 4 total scores.

Please help :) Also would love any feedback on the style of coding etc. Thanks in advance x

Answer 1

In the absense of code for people to see, we have something like

def get_stuff():
    for i in rnage(4):
        name = input("Name?")
        score = int(input("Score?"))

and another function

def TotalScore():
    pass

How do we call total score? Answer: Make sure we don't forget the user inputs and return them:

def get_stuff():
    names = []
    scores = []
    for i in range(4):
        names.append(input("Name?"))
        scores.append(int(input("Score?")))
    return names, scores

and take the scores in the summing function:

def TotalScore(scores):
    return sum(scores)

This, of course, changes the calling code. For example, you need to capture the returns when you call get_stuff :

names, scores = get_stuff()
total = TotalScores(scores)

Answer 2

I would rewrite the main function to be something like:

def GetStudentInput():
  score = 0
  for i in range (4):
      print("Mrs Pearson's Class Test Score Data")
      name = CheckStringInput("What's Your Name: ")
      score += CheckNumericInput("What's Your Score: ")
  print(score)

This eliminates the need for an extra function and avoids using a list since you don't appear to need the individual values elsewhere -- only the sum total.
