That exam I was "cheating" must be so long😂

Yes. You cannot get output of a void function without using globals. By using using globals you make the code complicated. After calling the void function, you need to know the name of the global variable to access the result. You need to assign it to other variables if you reuse the void function. With functions that return values, everything appears to be cleaner and reusable.

Teach me your ways master😂

I am already in a rabbit hole trying to learn what prompt is python 😂

Python

10 May 2026 10:34

def add(x, y):
    global result_add
    result_add = x + y


def get_input(prompt):
    global result_input
    result_input = int(input(prompt))


get_input("x")
x = result_input

get_input("y")
y = result_input

add(x, y)
print(result_add)

Python

That's not using add_void and get_input_void.

Python

I have finally hit None

Python

10 May 2026 10:21

I am rather quite enjoying it so far

Python

10 May 2026 10:20

Mind sharing what you have?

Python

10 May 2026 10:19

Yeah, are you stuck? Or don't have time to work on it?

Python

Why do I get the feeling that I am sent to do something undoable🙂

Python

10 May 2026 09:42

When I use the functions twice, do you want me to add the result of the previous to the second or you want two independent results from the same function?

Python

10 May 2026 09:27

More like

def user_input_void():
    global x
    x = int(input("Enter x: "))

Python

10 May 2026 07:58

And this is me using a return-value function

Python

10 May 2026 07:56

Let me tag them for you.
I have already sent it in this group

And what you did not know yet is that global variables pollute the global scope. You can assign values to it as well, not only read from them. It can get very confusing quickly.

12 lines of complicated code vs just 8 lines of clear code

The text to display to the user.

Python

10 May 2026 10:43

How does it compare to this one?

def add(x, y):
    return x + y


def get_input(prompt):
    return int(input(f"Enter value for {prompt}: "))


x = get_input("x")
y = get_input("y")
result = add(x, y)
print(result)

Python

It's just a variable.
I had to make a problem to solve or else they'd be no end point.

Python

10 May 2026 10:29

#monthly income
def income():
remaining_balance = int(input("Enter the remain: "))
expenses = int(input("Enter the expenses: "))
global total
total = remaining_balance + expenses
income()
print(f"your total income is: {total}")
#extended...
total = income()
print(total)

Python

Okay, then I'll be patient 😊

Python

The purpose is not to torture you but to make a point. We can go from what you have so far.

Python

10 May 2026 10:20

I wouldn't say I am stuck but I am not making that much progress 😂

Python

10 May 2026 09:50

It's not undoable, it's just gets messy.

Python

10 May 2026 09:47

Yes, user input 1 + user input 2

Python

10 May 2026 09:39

Let's make a deal. You do the versions with void function, where the user_input_void function is used twice to get the input from the user, and I do the one with the return statements. But also add the two inputs from the user with add_void.

Python

10 May 2026 09:24

#void-func extended:
def add_void(x,y):
global result
result = x+y
print(result)

add_void(3,3)
add_void(result, 4)
void_input = int(input("Enter your number?: "))
add_void(result,void_input)
Output: 10+input

Python

This is me using a global variable

Python

10 May 2026 07:55

So, let's compare those two versions then.
