Understanding How Python Executes Your Code Internally

How does Python actually execute your code? In this video, we'll dive into CPython's internals and follow a simple Python function through its complete execution pipeline: - Lexical Analysis (tokenization) - Abstract Syntax Tree (AST) creation - Bytecode compilation - Execution by the Python Virtual Machine We'll look at the actual CPython source code and see how Python transforms your code every step of the way. Whether you're a Python developer wanting to understand the language better, or just curious about how programming languages work, this video will give you a better understanding of Python's execution process.
