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])
Arrays in Python Type codes:
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.
