Editing OSX set up Python (Anaconda)

== Download and install Python ==

We're going to be installing Python using a collection of software that includes Python that, as a collection, is called '''Anaconda'''. Anaconda includes the Python programming language and a bunch of different pieces of software that are useful for data science and analysis. Although the collection includes all free software, it is put together by a commercial company called '''Continuum Analytics'''.

'''Note:''' Even if you already have a version of Python on your computer, we suggest you follow these instructions and download Anaconda. This will help ensure that you can follow along during our in-class activities, and will make it easier for mentors to help you if you get stuck on something.

=== Installation option #1 ===

<font size="+1">Try to download and install Anaconda from [https://communitydata.science/~mako/Anaconda3-2019.10-MacOSX-x86_64.pkg this file which contains Python 3.7 for OSX].</font>

=== Installation option #2 ===
If option 1 above doesn't work for any reason, download and install the Python 3.7 option from [https://www.anaconda.com/distribution/#download-section Anaconda's website], on the right. If necessary, scroll down to the "Anaconda 2019.10 for macOS Installer" section.

=== Install notes ===

*If you get stuck during the install process, ask a neighbor or raise your hand for help. [http://docs.continuum.io/anaconda/install.html#mac-install These instructions] may also be helpful. 

* At the end of the installer, you may be prompted if you'd like to send the installation package to the trash. Doing so won't damage the installation and will free up ~600MB of disk space on your computer.

== Test your Python install ==

To use Anaconda on MacOS, you will primarily use the Anaconda Navigator. This software helps manage multiple versions of Anaconda, as well as helps make it easy to launch Jupyter. 

The easiest way to launch the Anaconda Navigator is from inside the Applications folder:

The navigator will start up and greet you with a list of installed and available tools:

== Success! ==

You have tested your Python installation.

-One of the options (it's the middle option in the screenshot) should be called "Jupyter Notebook". Click that to open Jupyter Notebook! After a few seconds, you'll see a new tab open in your default browser. It will look something like this:

-Your default browser is where you'll be working with Jupyter Notebooks.
-If for some reason you '''don't''' see something in your browser, let a mentor know.
-When you launched the notebook from Anaconda, you may have noticed a Terminal window popped up, like this:
-[[File:Terminal.png|500px]]
-You can hide it, but do not close it during the whole time when you are using the Jupyter Notebook. If you close it, your Jupyter Notebook will be closed automatically.
-To close Anaconda, first go to your terminal, then, press "CONTROL+C" keys, you will see a new line on your terminal:
-[[File:Shutdownline.png]]
-Press "y" key, then press "RETURN" key. Now your Anaconda is closed :)
-Now Anaconda is not running on your terminal. You can press the "x" on the upper left corner of your terminal window to close the terminal as well.

-From the left hand side, choose '''Environments''', then choose the small "play" button. A menu will appear; choose the option 'Open with Python'. This will open an interactive Python window that we're going to use to test Python out with.

-Enter into the window '''print("Hello, World!")'''. You should see the text '''"Hello, World!"''' echoed back at you.
-Enter into the window '''<tt>exit()</tt>''' and you'll shut down the Python session and get a helpful '''<tt>[Process Completed]</tt>''' from the terminal, telling you your session is over.
