double underscore variables in python

Certainly! In Python, variables and methods prefixed and suffixed with double underscores (such as __variable__ or __method__()) have specific meanings and behaviors. These are called "dunder" (double underscore) methods or attributes. They serve different purposes, including special methods for operator overloading, name mangling, and more.
Let's explore these double underscore variables with explanations and code examples:
Dunder methods are often used for operator overloading. They enable classes to define behaviors for built-in Python operators such as +, -, *, /, ==, , , etc.
Using double underscores as a prefix (but not suffix) within a class name invokes name mangling. This feature is used to avoid name clashes in subclasses.
Variables enclosed by double underscores at both the start and end are typically reserved for system-defined names in Python. For instance, __name__, __doc__, etc., have special meanings.
Remember, while using double underscores in Python, it's crucial to understand their specific usage and purpose to write clean and maintainable code.
I hope this tutorial helps you understand the significance of double underscore variables and methods in Python!
