Python Arrays

There is a problem with lists, its violets are the basic property of an array which is a homogeneous collection of elements.

Though there is no in-built support for arrays in python, we can use a module name array to create an array data structure.

Syntax to create an array in Python using array Module:

import array

variable_name = array.array('Type code',[item1 , item2, item3,])

Example:

import array

arr = array.array('d', [1,2,3,4])

The Unicode decide the data type of all the elements and all the element data type should match the type code.

Syntax:

array.array(‘Type code or UniCode’ , [list of items] )

With the array module, we can only create an array of numeric elements.

In general, we use python lists as arrays, but theoretically, arrays cannot store different data types at once.

Python List

python_list = [1,2,3,4,5,"This is a List"]
print(python_list)

Array Module in Python

import array

python_array = array.array('i' , [1,2,4,5,6,7,])
print(python_array)

Conclusion:

We do not use a python array module to build arrays because we cannot perform a mathematical or arithmetic operation on array elements.
