Python Arrays in Linux - Explained with examples

This article covers how to use Array in Python. In fact, An array is a special variable, which can hold more than one value at a time.

Python Lists Vs Arrays

In Python, we can treat lists as arrays. However, we cannot constrain the type of elements stored in a list. 

For example:

# elements of different types
a = [1, 3.5, "Hello"] 
If you create arrays using the array module, all elements of the array must be of the same numeric type.
import array as arr
# Error
a = arr.array('d', [1, 3.5, "Hello"])

Output will give:

Traceback (most recent call last):
  File "<string>", line 3, in <module>
    a = arr.array('d', [1, 3.5, "Hello"])
TypeError: must be real number, not str
