Python’s object-oriented features let you model real-world entities, promote code reuse, and maintain large codebases. Whether you’re building REST APIs or GUI apps, OOP is essential.
Core OOP Principles
- Classes & Objects
- Blueprint vs. instance
- Encapsulation
- Private/protected attributes
- Getter/setter methods
- Inheritance
- Single vs. multiple inheritance
- super() usage
- Polymorphism
- Method overloading (via default args)
- Duck typing
- Abstraction
- Abstract Base Classes (abc module)
Example: Creating a User Model
python
CopyEdit
from abc import ABC, abstractmethod
class Person(ABC):
def __init__(self, name: str):
self._name = name
@abstractmethod
def get_role(self) -> str:
pass
class Admin(Person):
def get_role(self) -> str:
return "Administrator"
class Customer(Person):
def get_role(self) -> str:
return "Customer"
# Usage
users = [Admin("Alice"), Customer("Bob")]
for u in users:
print(f"{u._name} is a {u.get_role()}")
Benefits in Full-Stack Development
- Modular Services: Separate business logic from data access
- Reusable Components: Shared base classes for API controllers
- Maintainable Code: Easier to onboard new developers
Best Practices
- Keep classes small and focused (Single Responsibility)
- Favor composition over inheritance where possible
- Use dataclasses (@dataclass) for simple data holders
- Write unit tests for each class method
