Python Basic Data Structures

Array

Python's list is internally implemented as an array. Access an element by an index is O(1).

Indexing

Negative indices are also allowed. A handy way to access the last element is:

>>> a = [1, 2, 3]
>>> a[-1]
3

Title

Script

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book.

  >>> a = [1, 2, 3]
  >>> a[-1]
  3
