How does Python store lists internally?

Question

How are lists in python stored internally? Is it an array? A linked list? Something else?

Or does the interpreter guess at the right structure for each instance base

Answer 1

from Core Python Containers: Under the Hood
List Implementation:
Fixed-length array of pointers
* When the array grows or shrinks, calls realloc() and, if necessary, copies all of the items to the new space
source code: Include/listobject.h and Objects/listobject.c
