Welcome to Day 97! Today, we’ll focus on crucial design principles that can significantly enhance the quality of your Python code. Understanding and applying principles like SOLID, DRY, and KISS will lead you to create cleaner, more maintainable, and more readable code.

1. SOLID Principles

SOLID is an acronym for five design principles intended to make software designs more understandable, flexible, and maintainable.

• S (Single Responsibility Principle): A class should have only one reason to change, meaning it should have only one job or responsibility.
• O (Open/Closed Principle): Objects or entities should be open for extension but closed for modification. This means you should be able to add new functionalities without changing existing code.
• L (Liskov Substitution Principle): Objects of a superclass should be replaceable with objects of its subclasses without affecting the correctness of the program.
• I (Interface Segregation Principle): Clients should not be forced to depend upon interfaces they do not use. This principle deals with the disadvantages of implementing big interfaces.
• D (Dependency Inversion Principle): High-level modules should not depend on low-level…
