Learn how Python's dis module reveals bytecode, helping developers debug, optimize, and understand code execution at a deeper level.

Python Identity Operators

Python Identity Operators

Basics of Python

Python identity operators is and is not check if two variables point to the same object in memory. They differ from equality operators, which compare values. Use them to verify object identity, not content equality.

Python Identity vs Equality

Python Identity vs Equality

Python for Beginners

Python identity (is) checks if objects are the same, while equality (==) checks if their values match. Understanding this distinction helps prevent bugs and write more efficient code.
