Array

 

Array can be handled in Python by a module named array.
They can be useful when we have to manipulate only a specific data type values.
A user can treat lists  as arrays.
However, user cannot constraint the type of elements stored in a list.
If you create arrays using the array module, all elements of the array must be of the same type.
