Editing Python in Jupyter

We are going to practice writing and running Python programs (often called "scripts").

=== Download a Jupyter Notebook === 

Save the file <code>CDSW_Jupyter_test_notebook.ipynb</code> from the following link to your desktop: [https://communitydata.science/~groceryheist/CDSW_Jupyter_test_notebook.ipynb CDSW Jupter test notebook] 
(To save, (on Windows) right click the link and choose "save link as..." On a Mac, Option + click will do the same).

If you're using a new Mac, it may change the name of your file from ending in <code>.ipynb</code> to ending in .txt. If this happens, these steps should fix the problem:

* Type COMMAND-i (get info) and then click on the "type" section.
* Remove the <code>.txt</code> at the end of the file name and hit TAB.
* When your Mac asks you if you want to do this, say yes.
* Save it as a <code>.ipynb</code> file (rename it if you forget).

Make sure you save it on the CDSW folder you've created on your desktop. (Or drag it into that folder).

=== Open the Notebook in Jupyter Web Browser === 

Start Jupyter as you were instructed to in a previous step. 
In the Jupyter tab in your browser, navigate to your desktop in the list of folders and click on <code>CDSW_Jupyter_test_notebook.ipynb</code>.


=== Test the notebook ===

Following the instructions in the notebook, run the cell (by clicking the "run" button in the tool bar or press "ENTER + SHIFT") that says:
  print("hello world")

You should see "hello world" output right below. If that works you have a working setup for Python and Jupyter. If that doesn't work, you should ask for assistance!

Feel free to play around in the notebook. Try it out and explore!

P.S. Feel free to try out Python commands in this notebook. It's for you to play with!


=== Success! You have a working Python and Jupyter setup! ===
