Study Notes

Key Concepts of Python Inheritance

Inheritance allows a new class (child class) to inherit properties and methods from an existing class (parent class).
The parent class is also referred to as the base class, while the child class is known as the derived class.

Creating Classes

Any class in Python can function as a parent class, using standard class creation syntax.
To create a child class, specify the parent class as an argument during its definition.

Initializing Classes

The __init__() function is essential for initializing properties of a class.
If the child class defines its own __init__() function, it will not inherit the parent’s __init__() unless explicitly called using the parent's __init__().

Using super() Function

The super() function facilitates inheritance by automatically referring to the parent class, negating the need for explicit parent class naming.
It ensures the child class inherits all methods and properties from its parent, maintaining clean and efficient code.

Adding Properties and Methods

Properties can be passed through parameters to the child class's __init__() function.
If a child class contains a method with the same name as a parent's method, it will override the parent's method through method overriding.
