Confessions of a Code Addict

This post explores why Python lists multiply oddly when using the * operator. It dives into the internal implementation of lists in CPython, explaining how references are stored and how the * operator works. It provides a high level answer using the REPL and then delves into the details of the list object structure in CPython. It also discusses the internal object storage mechanism and how the CPython runtime executes the * operator for lists.
