Arrays and Lists, in Python, have the same way of storing data. But, Arrays can hold only a single data type elements whereas Lists can hold any data type elements.
import array as arr
My_Array=arr.array('i',[1,2,3,41])
My_list=[l,'abc',1.20]
print(My_Array)
print(My_list)
Output:
array('i', [1, 2, 3, 4])
[1, 'abc', 1.2]
In the example above, in My_Array, typecode used is i. This typecode represents signed integer whose size is 2 bytes.
