How variables works in Python | Explained with Animations

This video tries to explain how variables or name bindings work in Python and their internal representations like PyObject and PyVarObjects, using animations. Intermediate level concepts like reference counting, garbage collection, how lists work internally, why python is a dynamically typed language, interning, None objects, equality operators like '==' and 'is', how 'del' works, how variables are passed into functions(pass by reference), issues with default mutable parameters, operator overloading and behaviour of augmented arithmetic assignment operators, the behaviour of mutable element in the tuple are also explained. It also shows how mutable and immutable data types behave differently in some scenarios. This knowledge should be useful for people coming from other languages like C, Rust, or Golang and may enable them to write better Python code.
