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

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

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?.

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.

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

Python

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

Python

08 May 2026 05:04

What if you want to do something like add wto numbers then add another number to that result?

Python

08 May 2026 05:02

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

Python

08 May 2026 04:53

Let me send you the code then.
I will write it now

Python

08 May 2026 04:52

Last night or theprevious week is irrelevant, Do it now

Python

08 May 2026 04:49

I did yes.
I normally would've done that but, I had a very little time

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

08 May 2026 11:06

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

08 May 2026 05:20

#Using a return value function:
def add(x,y):
return x+y
total= add(3,3)
print(f"Charly, this your total: {total}")

"""What if you want to do something
like add wto numbers then add an
other number to that result?"""
a,b = 2,2
total += a+b
print(total)

Now, to my beginner eyes, I get 6 each time.
So, I wonder what makes one different to the other in this case!

Python

08 May 2026 04:59

#Using a return value function:
def add(x,y):
return x+y
total= add(3,3)
print(f"Charly, this your total: {total}")

Python

08 May 2026 04:53

The difference is not about how many times you call it but returning something or not

Python

08 May 2026 04:51

I tried it last night.
The week before. I have written the same code over and over.
But, one is a void function, the other is a returning value function. But If I use a variable with the void function, I am getting the same results. So, I wondered what makes one different to the other?

Again, not to bo rude but incetivate you to be more proactive 👍
