In this video, we cover the concepts of mutable and immutable objects in Python along with how variables actually work. You’ll understand how Python uses references instead of storing values directly, and why changes affect some objects but not others.
We also explain the id() function to show how objects are stored in memory and how identity works in Python. Concepts like same object vs new object, list vs string behavior, and in-place vs new creation are demonstrated with simple and practical examples, so you clearly understand when and why things behave differently.
