Python Program to Using a package

To use a package in Python, you first need to install it using a package manager like pip. Once the package is installed, you can import it in your Python code using the import statement.

pip install numpy​

Once the installation is complete, you can import NumPy in your Python code like this :

import numpy as np​

 

The above code imports the NumPy package and assigns it the alias "np", which is a commonly used convention in the data science community. You can then use the functions and classes provided by NumPy in your code, for example :
