Opening a Jupyter Notebook

Opening a Jupyter Notebook

In this section, you will learn how to open a Jupyter notebook on Windows and MacOS.

One way problem solvers can write and execute Python code is in a Jupyter notebook. Jupyter notebooks contain Python code, the output that code produces and markdown cells usually used to explain what the code means.

On Windows, a Jupyter notebook can be started from the Anaconda Prompt, the Windows start menu and Anaconda Navigator.

3 ways to open a Jupyter notebook:

  • Windows Start Menu

  • Anaconda Prompt

  • Anaconda Navigator

Open a Jupyter notebook with the Windows Start Menu

One simple way to open a Jupyter notebook is to use the Windows Start Menu. Note that the Anaconda distribution of Python must be installed to use the Windows Start Menu to open a Jupyter notebook. Download Anaconda at the following link: Anaconda.com/downloads

Open the Windows start menu and select [Anaconda3(64 bit)] --> [Jupyter Notebook]

This action opens the Jupyter file browser in a web browser tab.

In the upper right select [New] --> [Python 3]

A new notebook will open as a new tab in your web browser.

Try typing this in the first cell in the notebook to the right of the In [ ]: prompt:

import this

Then click the run button in the middle of the menu at the top of the notebook.

Open a Jupyter Notebook with the Anaconda Prompt

Another method to open a Jupyter notebook is to use the Anaconda Prompt.

Go to the Windows start menu and select [Anaconda Prompt] under [Anaconda3].

If you don't see the Anaconda Prompt in the Windows Start Menu, then you need to install the Anaconda distribution of Python. Download Anaconda at the following link: Anaconda.com/downloads

The Anaconda Prompt window should look something like the image below.

At the Anaconda Prompt type:

> jupyter notebook

This command starts the Jupyter notebook server. The output in the Anaconda Prompt will look something like the output shown below:


Copy/paste this URL into your browser when you connect ...

        http://localhost:8888/?token=6bdef677d3503fbb2 ...

[I 16:14:12.661 NotebookApp] Accepting one-time-token ...

A web browser should open, and you should be able to see the Jupyter file browser. If a web browser doesn't open automatically, you can copy the web address from the Anaconda Prompt and paste it into a web browser's address bar.

Open a Jupyter Notebook with Anaconda Navigator

One additional way to open a Jupyter notebook is to use Anaconda Navigator. Anaconda Navigator comes with the Anaconda distribution of Python. Open Anaconda Navigator using the Windows start menu and select [Anaconda3(64-bit)] --> [Anaconda Navigator].
