**array** module in Python is used to create arrays of homogeneous data types. An array is a data structure that stores multiple values of the same data type in a contiguous block of memory. It is more efficient in terms of memory and speed compared to a list. The
**array** module provides a more memory-efficient and fast alternative to Python's built-in list data structure for arrays of homogeneous elements. It also provides several functions for creating and manipulating arrays.
