🚀 Python OOP Concepts You Should Know
🔹 @staticmethod → No access to class or object
🔹 @classmethod → Access to class (cls)
🔹 Instance Method → Access to object (self)
🔹 MRO (Method Resolution Order) → How Python resolves methods in inheritance.
🔹 Method Overriding → Child class redefines parent method.
🔹 Method Overloading → Achieved using default arguments or *args, **kwargs.
🔹 Composition vs Inheritance
• Inheritance = "is-a" relationship
• Composition = "has-a" relationship
🔹 Dunder Methods → init, str, repr, etc.
🔹 Encapsulation
• _protected
• __private
🔹 Diamond Problem → Resolved using Python's MRO.
💡 Learn the why behind these concepts, not just the definitions.
