How would you change the structure of a program in Python based on OOP?

Question

Python

Dear programmers, I'm starting to learn OOP based on Python and I can't figure out how to make my program simpler and more understandable. There is a procedure with a cycle in which a lot of data is iterated and changed.

###
for X1 in obj():
     X1 = ModifyValueX1(X1)
     Y2 = ModifyValueY1(Y2)
###и т.п.

What program structure would you make if you need to change the ModifyValue1..x data handlers with different input parameters?
the functions ModifyValueX1-X2-X3 are similar, X2 r is based on X1 for example, you just need to change the code a little. Or OOP methods will not work?

Answer 1

The structure of your program is not at all clear, so it's impossible to say exactly where to shove OOP.
ModifyValueN can be replaced with something like this:

def modify(value, func):
    return func(value)

And use something like this:
PS Read PEP8, I beg you

Answer 2

OOP makes the program more difficult - don't use OOP unless it's necessary
Just make a function
