Principles of Python Programming from Shivani Salavi's blog
Python adheres to a set of guiding principles that contribute to its readability, efficiency, and maintainability. These principles are collectively known as the "Zen of Python."
The Zen of PythonTo access the Zen of Python in your Python interpreter, simply type import this. You'll see a collection of aphorisms that influence Python's design. (Python Training in Ahmednagar)

Use code Here are some key principles:
- Readability Counts: Python emphasizes clear and concise code.
- Simple is Better Than Complex: Avoid unnecessary complexity.
- Errors Should Never Pass Silently: Python's error handling mechanisms are designed to prevent silent failures.
- Practicality Beats Purity: While Python promotes clean code, it also acknowledges that practical considerations sometimes outweigh theoretical purity.
Object-Oriented Programming (OOP) Principles in PythonPython supports OOP concepts, which are essential for building complex applications:
- Encapsulation: Bundling data (attributes) and methods (functions) that operate on the data into a single unit (class).
- Abstraction: Hiding implementation details and providing a simplified interface. (Python Course in Ahmednagar)
- Inheritance: Creating new classes (subclasses) that inherit attributes and methods from existing classes (superclasses).
- Polymorphism: Using a single interface to represent different types of objects.
SOLID PrinciplesThe SOLID principles are design principles for creating maintainable and extensible software. While not strictly enforced in Python, they provide valuable guidance for writing clean and well-structured code:
- Single Responsibility Principle (SRP): A class or function should have only one reason to change.
- Open-Closed Principle (OCP):Software entities should be open for extension but closed for modification.
- Liskov Substitution
(Python Classes in Ahmednagar)
Interface Segregation Principle (ISP):Clients should not be forced to depend on interfaces they do not use. Dependency Inversion Principle (DIP):High-level modules should not depend on low-level modules. By following these principles,
