Jupyter Notebook is an open-source web application that allows you to create and share documents containing live code, equations, visualizations, and narrative text. It is widely used in data science and machine learning projects. This article will guide you through the process of installing and running Jupyter Notebook on a Windows operating system.

Step 1: Install Python

Jupyter Notebook requires Python to be installed on your system. Follow these steps to install Python:

1. Download the latest version of Python from the official Python website.
