Numpy is funadamental package for numerical computations in python.
NumPy is a Python library for creating and manipulating vectors and matrices.
Support different datatypes.
Supports N-dimensional array objects that can be used for processing multi-dimensional data.
Using Numpy we can perform:-
- 
Mathematical and logical operations on arrays 
- 
Fourier transforms 
- 
Linera Algebra operations 
Advantages of Numpy
- 
Numpy supports vectorized operations. 
- 
Numpy is faster than operations carried out on python lists. 
- 
Numpy use less memory in runtime than python list.
