This quick guide will teach you how to open a new Jupyter Notebook in Mac OS or Windows. It assumes that you have already installed Jupyter using the Anaconda distribution. For details on how to install Jupyter on your computer, using the Anaconda distribution, read this article on how to set up your system to start coding in Python:

Step 2. Once the Terminal app opens, navigate to the desired folder, using the cd command. For details on how to use the command line, read this tutorial on how to use the command line, part 1 and part 2:

• Intro to Programming: How to Use the Command Line (Part 1)
• Intro to Programming: How to Use the Command Line (Part 2)

Please note that your Terminal colors and text may differ.

How to Open a Jupyter Notebook on Windows

NOTE: For best performance, I strongly recommend Firefox or Chrome as your browser when using Jupyter notebook on a Windows computer.

Step 1. Find and open the Anaconda Prompt app using the search bar. Alternatively, you can use the Anaconda Powershell Prompt. The Anaconda Powershell Prompt has more bells and whistles and it is generally nicer to work with.
