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

Python

10 May 2026 07:52

I use the variable I created.
And yes you will ask, how would you do that without the return function?
I use global variables

Python

10 May 2026 05:29

Yes, I wrote exactly this. I forgot to send it to you.

What are you trying to achieve with these questions?

Python

Something like

#addition
def add():
    total= num1+num2
    print(total)

#using the function
num1= int(input("Enter num1?: "))
num2= int(input("Enter num2?: "))
add()

num1= int(input("Enter num1?: "))
num2= int(input("Enter num2?: "))
add()

Python

I'd do the same for the subtraction.

Python

I thought your question was more complicated than it was.
I defined separate functions. One calculates savings and the other calculates revenue just to use the addition and subtraction.
I was struggling to find something they have in common where I'd need to use both addition and subtraction.
After some headache, I reread your question and it was not even that difficult 😂

Guys what is OOP in python

Python

They lead to an insight.

Define void functions add and subtract. Use them somewhere else.

Python

08 May 2026 09:57

If you have add and subtract void functions, you either do add or subtract, but can you do both? First one then the other?

Python

08 May 2026 09:35

Exactly where I wanted to get you to and exactly the reason why you should be trying things out.

Python

08 May 2026 05:45

Inside the function or outside the function?

Python

08 May 2026 05:34

I meant something like this:

add(add(2,3), 5)

Python

08 May 2026 05:32

That looks complicated. Now try it with returns

Python

08 May 2026 05:29

#Using a void fucntion with a variable
def add(x,y):
global addition
addition = x+y
print(addition)
add(3,3)

"""of course I meant using
the void functions"""
b,a = 2,2
addition += b+a
print(addition)

Python

10 May 2026 07:57

This is me using a global variable

Python

10 May 2026 07:55

So, let's compare those two versions then.

Python

What do you do when you want to use the result from the first addition in the second?

Python

I am working on a personal project I have concluded the project but I want to add wallet features that each user can transfer into a dedicated virtual account number and it will be captured by the portal in Django

Python

09 May 2026 19:04

So, when you want to reuse add what would you do?

Python

09 May 2026 18:51

Here's an example of addition:
#addition
def add():
total= num1+num2
print(total)
#using the function
num1= int(input("Enter num1?: "))
num2= int(input("Enter num2?: "))
add()

oop stands for object oriented programming, its serves the purpose of encapsulation ,abstraction , inheritance and isomorphism .
classes are used in python to do this , a class instance can be initialized with some data then the methods of that class can use that data internally to do smthing (encapsulation) . i see making a class in itself as a way of abstraction . and these classes can be sub classes or parent classes of other classes so inheritance . i dont know much about polymorphism

Python

Alright.
I will try to do so when I am back home👍

Python

08 May 2026 11:03

I am doing both inside the function or outside?

Could you give me a prompt that would require me to do both?(addition and subtraction)
I always aim to solve the problem regardless of the route that I am taking.
That's why I asked, do they both (void-function and value-returning functions) lead to the same outcome?.

Python

I was in a rush last night.
I had the exam this morning and I wanted to quickly understand.
I could write a void-function and a return valid function but I didn't know what actually made them different. Like are they interchangeable or not. So, I was limited on time to go deeper on it.
Otherwise, I would've taken my time with it.

Python

08 May 2026 05:52

I am finding it hard to do.
I will take it as a homework.
Thank you for working with me

Python

08 May 2026 05:35

res = add(2,3)
res1(res, 5)

if you find it hard to understand

Python

08 May 2026 05:32

I have.
With returns I don't need to use a global variable

Python

08 May 2026 05:31

So, I could use the variable outside the function

Python

08 May 2026 05:20

of course I meant using the functions
