Hello, future Python expert! Today, we'll dig into a significant feature of Object-Oriented Programming (OOP) — inheritance. Much like children inheriting characteristics from their parents, child classes in OOP can adopt properties and behaviors from parent classes in the same vein.
Our goal here is to comprehend the purpose, different types, and the implementation of inheritance, with speculative attention on simple inheritance. With inheritance, we can reuse code, minimizing repetition and maximizing efficiency.
Inheritance in OOP mirrors inherited characteristics in life. We create child
classes that receive properties and behaviors from a parent
class. Consider a school environment: all kinds of teachers share common actions (such as teaching), regardless of the subjects they teach. We could create a base Teacher
class with these shared behaviors and then generate MathTeacher,
ScienceTeacher,
etc., which inherit these common behaviors and add others unique to their respective subjects.
Python supports multiple types of inheritance — including single, multiple, multilevel, and more. In this lesson, we'll turn our attention to single inheritance, where a child class inherits from a solitary parent class. This type of inheritance is the most common and basic among all existing.
