Editing OSX set up Python (Anaconda) (section)

== Download and install Python ==

We're going to be installing Python using a software collection that includes Python. The 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.

=== Download option #1 ===

<font size="+1">Try to download the installer from either of these places:</font>

* [https://repo.anaconda.com/archive/Anaconda3-2023.03-MacOSX-x86_64.pkg This file which contains Anaconda and Python 3.10 for MacOS for Intel-based Macs]
* [https://repo.anaconda.com/archive/Anaconda3-2023.03-MacOSX-arm64.pkg This file which contains Anaconda and Python 3.10 for MacOS for the newer M1 Macs]

=== Download option #2 ===
If option 1 above doesn't work for any reason, download the Python 3.10 option from [https://www.anaconda.com/distribution/#download-section Anaconda's website]. If necessary, scroll down to the "macOS Installer" section. 

=== Installation ===

{{Notice|If you are on MacOS 10.15 (Catalina), '''you must follow an additional step''' which is noted below. If you don't, Anaconda won't work quite right! }}

To install Anaconda, simply open the package and follow the prompts. You may be asked to enter your password by Package Installer.

=== 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.
