In this lesson, we learn about arrays and how they are used in Python!


In Python, an array is just an ordered sequence of homogeneous elements. In other words, an array can only hold elements of one datatype. Python arrays are basically just wrappers for C arrays. The type is constrained and specified at the time of creation.

Initializing Arrays

Python arrays are initialized using the array library:

import array
new_array = array.array('type', [list])

Here type defines the data type of array and list is a python list containing homogenous elements.
