unction return values only working once in python

Question

The code below runs and prints out the values returned from the two functions test_value(address) and checkRepeatCount(address) when i try to add the two value returned i None as the result. Anyway to fix this?


def check(address):
   
   ## define point variables
    pass_invalid_char = test_value(address)
    pass_repeat_count = checkRepeatCount(address)

    if pass_invalid_char == False:
        return print("Invalid character")
    else:
        pass
    
   total = pass_invalid_char+pass_repeat_count
   print(total)



check("hello")

Function 1 test_value

def test_value(value):
    return print(30)

Function 2 checkRepeatCount

def checkRepeatCount(value):
    return print(20)

Thats how im returning the function values

You code is not reproducible, what are `test_value` and `checkRepeatCount`? — mozway, Mar 16 '22 at 14:52
The function `print()` always returns `None`, and also any function with no explicit return will return `None`. So your function is always returning `None`. Did you mean to do `return total` insead of `print(total)`? — Green Cloak Guy, Mar 16 '22 at 14:53
In short, your function does not return anything. It merely prints and exits. You must have a `return` line for it to pass something back to the caller. (Note that you can have it `print(total)` and `return total` if you want both behaviors) — JNevill, Mar 16 '22 at 14:56
both functions return a number, im trying to get the total number of the two added together. When i run the two individually they work, they are being imported from their own file — Zayne komichi, Mar 16 '22 at 14:58
you should add the entire code including that of the mentioned functions so that people can reproduce the problem. — Hasan Aga, Mar 16 '22 at 15:04
@jNevil could you post something so i can close this question your answer got me to the solution — Zayne komichi, Mar 16 '22 at 15:05
@Zaynekomichi ok, but why not edit this question and make it better instead? — Hasan Aga, Mar 16 '22 at 15:06

In both functions was returning a print statement with value

def test_value(value):
    return print(30)

I was supposed just to return the number on its own like so

def test_value(value):
    return 30
