g. NumPy

NumPy is an open-source framework for Python. It is used for scientific computing. It supports large multidimensional arrays and matrices, and functions to operate on them.

h. SciPy

SciPy is a Python library that you can use for scientific computing. It has modules for linear algebra, interpolation, fast Fourier transform, image processing, and many more. It uses a multidimensional array from the NumPy module.

Let’s create some very simple program to add two numbers

a=10 b=20 print(a+b)

Output:

30
