函数外返回错误：(Python)

Question

Here, for this code I'm getting an error on return outside the function. Can I anyone explain why is this so?

import numpy as np 

name = input().split(" ")
arr = [int(num) for num in name]
sum=[]
for i in arr:
   sum=+i
return sum

Answer 1

return statement only makes sense inside functions. To show or display infos use print(sum)

Answer 2

You are using the return keyword outside of a function. If you want to display the sum on screen use: print(sum) .

Answer 3

You can't use the return statement outside a function. It is used to end the execution of a function and return the results of that particular function. You can simply modify your script to a function like this.

import numpy as np 
    
name = input().split(" ")
arr = [int(num) for num in name]

def function_name(array):
  sum=[]
  for i in array:
    sum=+i
  return sum

variable_name = function_name(arr)
