Inside Python’s List: C‑Level Implementations of Core Methods

This article walks through the CPython source code that defines list’s built‑in methods—append, insert, pop, index, count, remove, reverse, clear, and copy—explaining how each method is wired into the type object, the underlying C logic, time‑complexity characteristics, and common pitfalls such as reference‑count handling and shallow versus deep copying.

Which sequence operations does Python’s list support and how are they implemented?

The article explains the various sequence‑type operations that Python lists provide—concatenation, repetition, indexing, slicing, and element assignment—detailing how each is realized in CPython through the tp_as_sequence and tp_as_mapping slots and the corresponding C functions such as list_concat, list_repeat, list_subscript, and list_ass_subscript.
