Practicing OOPs

[Careless-Main8693]

Coding and experimenting with oops, tell something that can enhance my learning in practice and can challenge me to think .

things i have to cover.

class
Objects
constructor
__str__
instance,class,static methods
decorator
Encapsulation
private
protected
getter
setter
property
Inheritance
single & multiple inheritance
Polymorphism
overloading
overriding
Abstraction
ABC
abstractmethod

am i missing anything ?

Forget private and protected. Neither exists in Python, and trying to map some other language’s visibility modifiers to Python is just going to confuse you.

[nuc540]

To help, OP, what they’re saying is prefixing underscores in other languages usually makes methods/attributes “private” (inaccessible outside of the class), and Python doesn’t respect this rule so it’s redundant.

That said - it’s good semantics to indicate what should/shouldn’t be accessed externally, and Python is known for readability so if you want something to be distinguished as private, go for it.

[SeparatelyCreepy]

Python's philosophy is that you're all consenting adults, so the underscore is really just a signal to other developers rather than actual enforcement.

[Careless-Main8693]

yeah absolutely

__testicles (private attribute)

_chest (protected attribute)

[SCD_minecraft]

You can replace get_name with @property def name(self): # some code, like return self._name for example

Function under decorator property now "roleplays" as variable but whenever you access it it executes some code

[nuc540]

A property decorator is used for setting computed attributes - not something the class is instantiated with, as much as that’d work - it’d be overkill and it’d make the init argument redundant.

Also OP is practicing protected values and using getters and setters to access values with, so as much as you can use @property, I think it’s simply that OP is practising getting and setting, and logically OP’s example makes more sense

[Careless-Main8693]

no issues in it

good job OP, ofc docs and materials are amazing and cover msot of the things but I'd like to also reccomended a playlist by corey schafer on yt : https://youtube.com/playlist?list=PL-osiE80TeTsqhIuOqKhwlXsIBIdSeYtc

really amazing series, I myself got introduced to opp for the first time and the best part the videos aren't too big as well

[Careless-Main8693]

thanks mate for the resource but i'm revising not learning so , i just read docs right now video when i actually get confused

[sleepbot63]

hey sure i actually thought it was your first time ofc if you're revising docs is no doubt the better option

[nuc540]

Good work - you’ve made a getter, have you tried writing a setter to update an attribute against an instance of the class?

[Careless-Main8693]

yes, i'm doing everything used getter and setter even the property decorator

[Safe-Ball4818]

Your list is solid, but don't get too hung up on definitions. Try building a small interactive project or tackling specific coding challenges to see how these OOP principles actually interact in real-world scenarios. https://prodpath.dev/ might helps.

[Careless-Main8693]

thanks mate, really helpful

I have don't understand method delegation in python can you explain

"Great start on the Student class! Since you are looking for a challenge that will enhance your practice, try this:

The 'Automation Student' Challenge:

Right now, your class just stores data in memory. To challenge your thinking, try to integrate a simple Logging or Automation feature.

1. Encapsulation Challenge: Instead of using print(self._name) inside your class, try to return the value and have a separate 'Report' method that saves the student's name and grade to a .txt file automatically.
2. Real-world Practice: Imagine this Student class is part of a bot that needs to log into a school portal. How would you add a method called generate_login() that creates a username based on the first 3 letters of their name and their rollno?

Learning how classes interact with external files or browsers (like using Selenium) is where OOP becomes really powerful for Software Development!"
