Rules and naming conventions in Python programming language

Python is an interpreted language that is widely used for various purposes ranging from web development to scientific computing and automation. In order to write efficient and understandable code in Python, it is essential to follow certain rules and conventions that govern the language. This tutorial will provide an overview of these important rules and naming conventions, including topics such as naming variables,  functions, classes,  packages and modules in Python. Whether you are a beginner or an experienced programmer, this tutorial will be a valuable resource for ensuring your Python code is clean and easy to understand.

• Every programming language has its own set of rules and naming conventions. 
• These rules and conventions are designed to make the code more readable and consistent. 
• Python has some of the strictest rules and naming conventions of any programming language.
• Python naming conventions are designed to make code more readable. 
• Python is case sensitive thus the name my_var is different from My_var
• Python uses indentation to define code blocks. 

Naming Conventions in Python
