Jupyter Notebook 101: Installation and Getting Started (Windows/Linux/macOS)

Jupyter Notebook is a powerful tool for interactive computing, allowing you to create and share documents that contain live code, equations, visualizations, and narrative text. Here's a step-by-step guide to installing and getting started with Jupyter Notebook on Windows, Linux, and macOS.

Windows:

1. Install Python: If Python isn't already installed on your system, download and install it from the official website. During installation, ensure that the option to add Python to your system PATH is selected.
2. Install Jupyter Notebook: Open a command prompt and execute the following command to install Jupyter Notebook using pip, Python's package manager:

Using Jupyter Notebook:

Once Jupyter Notebook is launched, it will open in your default web browser, displaying the Jupyter dashboard. From there, you can create new notebooks, open existing ones, and execute code cells. Explore the toolbar and menus to access various features and settings.

Remember to save your work regularly and shut down the notebook server when you're done by closing the terminal or command prompt window running the server.

Now you're all set to use Jupyter Notebook on Windows, Linux, or macOS. Happy coding!
