Jupyter Notebook

Launch it.

Start a command window
Go to the root directory where the notebook needs to be opened.
For test and in order to be able to follow all that’s going on, use a completely empty directory
Type: jupyter notebook and hit [Enter]
While the notebook opens in the web browser of your computer, it might be that the output in the command windows is:

  [w 10:08:38.454 NotebookApp] Error loading server extension
              jupyter_nbextensions_configurator
                  Traceback (most recent call last):

              [I 10:08:38.461 NotebookApp] The Jupyter Notebook is running at:

              [C 10:08:38.572 NotebookApp]

When the above is the case and ... to stop the complaint use pip to install following:
```
  pip install jupyter_nbextensions_configurator
            
```
To be sure, quit the notebook in the web browser, close the command window and launch it again.
Type as above jupyter notebook and hit [Enter]

As before the notebook should open in the web browser but now the status messages in the command window should look as:

  [I 10:38:23.165 NotebookApp] [jupyter_nbextensions_configurator] enabled 0.4.1

                  To access the notebook, open this file in a browser:
                      file:///cC:/Users/defossez/AppData/Roaming/jupyter/runtime/nbserver- 9688-open. htm!
                      Or copy and paste one of these URLs:

Using it

Hit [New] and add a kernel, select Python 3 from the fall down menu.
To find your way around, click [Help] and hover buttons to discover their function.
For a non-mac machine, click [ctr1][Shift][P] for a list of all possible commands.
The notebook has no title, so better give it one. Click right of Jupyter the title Untitled1. In the popup give the notebook a meaning full name and click then the [Rename] button.
Start adding stuff to the notebook.
A notebook has two modes: command mode [hit esc key] and Edit mode [hit Enter key].
Edit mode is also invoked when clicking in a cell, then the cell turns green.
Edit mode is also indicated by a pencil icon in the right-top of the window.
Command mode, by hitting esc turns a cell blue and removes the pencil icon from the window.
Test coding python:
Click the available cell and type: print ('Hello world')
To execute the code in the cell, click the [Cell] tab in the upper menu. Options to run the cell are presented:
[Run Cells]: just execute the code and presents the output below the cell.
- [Run Cells and Select Below]: Runs the code in the cell and select the cell below after execution.
- [Run Cells and Insert below]: Runs the code in the selected cell and inserts a new cell below.
- [Run All]: run all available cells.
Add some text in the notebook:
- Text is written in markdown and later on translated to HTML.
- To add text, add a new cell by clicking the [Insert] tab button and select one of the two options, insert a cell above or below the selected cell.
- Select the new cell and click the [Cell] tab button and select [Cell Type] as [Markdown].
- Enter some markdown text and then run or translate the markdown to HTM by hitting [Ctrl Enter]
This is the short introduction to notebooks.
Find listed below some useful things:
- Enter ! in a cell to execute bash commands.
- % and %% lines for bash commands and magic command. To list all possible commands enter in a cell %1smagic
