Python lists are ordered collections of elements and, in Python, are implemented as resizable arrays. An array is a basic data structure that consists of a series of contiguous memory locations, and each location contains a reference to a Python object.
Lists shine in accessing, modifying, and appending elements. Accessing or modifying an element involves fetching the object reference from the appropriate position of the underlying array and has complexity O(1). Appending an element is also very fast. When an empty list is created, an array of fixed size is allocated and, as we insert elements, the slots in the array are gradually filled up. Once all the slots are occupied, the list needs to increase the size of its underlying ...
