    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.
