How To Use IPython Jupyter Notebook To Develop Python Code

Leave a Comment / Python Tutorial / Jupyter Notebook

IPython is an enhanced Python interactive environment, you can run all Python source code in IPython. And it provides more features that make your development process easy. Jupyter notebook is a browser-server based website tool that can save your python source code in a .ipynb notebook file, and then when you submit the python source code to your local Jupyter web server, it will start an iPython kernel to run the source code, and then display the result or error messages just below your python source code in the web page for interactive development. This article will introduce how to use iPython and Jupyter notebook to develop interactive python source code with examples.

1. Install IPython.

  1. Before installing IPython, you can run the command $ pip3 show ipython to check whether it has been installed or not. This command will show it’s version and installation directory. 
    (base) :~$ pip3 show ipython

3. Install Jupyter NoteBook.

Jupyter notebook is a browser-server-based website tool that can help you to write and run Python source code interactively. When you run it, it will start a web server, and then you can create a working folder and notebook file ( which file extension is .ipynb ) in it. In each notebook file, you can write text in line cell input text box and mark the text as Code ( python source code ), Markdown ( comments), Raw NBConvert, or Heading type.

Then you can submit the text to the Jupyter webserver to execute. If you submit Python source code, the Jupyter web server will create an iPython process to run it, and the execution result will be displayed below the python source code on the web page immediately.

But before use it, you should install it first, you have two ways to install it.

  1. Install Anaconda: Anaconda integrates with Jupyter by default, so after installing anaconda, you can use Jupyter directly. You can refer to How To Install Anaconda On Linux, Windows, macOS Correctly.
  2. Use pip to install Jupyter: Open a terminal and run $ pip3 show jupyter to check whether Jupyter has been installed or not. Below output means Jupyter has been installed. 
    ~$ pip3 show jupyter
Name: jupyter
Version: 1.0.0
Summary: Jupyter metapackage. Install all the Jupyter components in one go.

  3. If Jupyter is not installed, run $ pip3 install jupyter to install it. It will download and install a lot of dependency packages like below. 
    $ pip3 install jupyter

4. Run Jupyter Notebook Web Server.

  1. After Jupyter has been installed successfully, you can run the command $ jupyter notebook in terminal to start the Jupyter web server. 
    ~$ jupyter notebook
[I 22:21:57.057 NotebookApp] Writing notebook server cookie secret to /run/user/1000/jupyter/notebook_cookie_secret
[I 22:21:57.234 NotebookApp] JupyterLab extension loaded from /home/zhaosong/anaconda3/lib/python3.7/site-packages/jupyterlab
[I 22:21:57.234 NotebookApp] JupyterLab application directory is /home/zhaosong/anaconda3/share/jupyter/lab
[I 22:21:57.235 NotebookApp] Serving notebooks from local directory: /home/zhaosong
[I 22:21:57.235 NotebookApp] The Jupyter Notebook is running at:
[I 22:21:57.236 NotebookApp] http://localhost:8888/?token=a1ccb7865e275163dbd751856698a601f6f69feb2627b266
[I 22:21:57.236 NotebookApp] Use Control-C to stop this server and shut down all kernels (twice to skip confirmation).
[C 22:21:57.254 NotebookApp] 
    
    To access the notebook, open this file in a browser:
        file:///run/user/1000/jupyter/nbserver-13959-open.html
    Or copy and paste one of these URLs:
        http://localhost:8888/?token=a1ccb7865e275163dbd751856698a601f6f69feb2627b266
  2. Copy and browse the above HTTP url http://localhost:8888/?token=a1ccb7865e275163dbd751856698a601f6f69feb2627b266 to go to the Jupyter website home page. Please do not lose the token generated in the url, if you do not provide the token, you will enter the below error page that requires you to input the token value.

    Password or token:          Log in
Token authentication is enabled
If no password has been configured, you need to open the notebook server with its login token in
the URL. or paste it above. This requirement will be lifted if you enable a password.

The command:
       jupyter notebook list

will show you the URLs of running severs with their tokens. which you can copy and paste into

your browser. For example:

        Currently running servers:
        http://localhost:BB88/?token-cBde56fa. .. :: /Users/you/notebooks
or you can paste just the token value into the password field on this page.
See the documentation on how to enable a password in place of token authentication. if you
would like to avoid dealing with random tokens.
  3. If you browse url http://localhost:8888/?token=a1ccb7865e275163dbd751856698a601f6f69feb2627b266 with the correct token value, then you will be directed to the Jupyter home page.

5. Execute Python Code In Jupyter Interactively.

  1. On the Jupyter notebook web server home page, click the New drop-down menu list on the top right corner, and you can select Python 3 menu item to create an executable python 3 notebook file. Click the Folder menu item to create a working folder.
  2. Click the file name Untitled.ipynb, you will go to the notebook editor page like below. Click Untitled in the top left corner, you can change the Jupyter notebook file name.
    jupyter-ipynb-file-editor-page
  3. Then you can input text in the line cell input text box. You can also specify the line cell text value type from the drop-down list at the end of the toolbar icons. There are four text value types: Code ( python source code ), Markdown ( comments ), Raw NBConvert, Heading.
  4. If you select Code type for the line cell text, then click the Run button will submit the line cell text value to the Jupyter server to run. Then Jupyter will start an iPython kernel to run the python source code on the server-side.
  5. You can input all kinds of python source code, such as to define python function, import libraries even run matpolib code to generate the chart, then the chart image will be displayed on the web page also.
