Python has a lot of convenient data structures (lists, tuples, dicts, sets, etc) which can be used to make other 'conventional' data structures (Eg, I can use a Python list to create a stack and a collections.dequeue to make a queue, dicts to make trees and graphs, etc).p vote 2 down vote favorite. 1.

Python Arrays. An array is a type of variable that can hold one or multiple values in a single variable. The Arrays are similar to Python list, that we learned in the last chapter. However, the difference is a list can hold multi-type elements whereas the arrays can hold only single type e.g. an array of only strings or numbers.
