Installing Python

So You've Decided to Install Python

If you're on OSX or Ubuntu…

What version were we using? →

We're using 3.x for this class
So… you'll probably have to install a new version side-by-side with the existing default Python on OSX and Ubuntu

QUESTION - What version are we using in class?

Open up:
- cmd.exe on Windows (start → run → type "cmd.exe" and run)
- terminal on OSX (⌘-space to search spotlight → type "terminal")
- terminal on Ubuntu (you probably know how to do this on if you're on Linux!)
Type in the following command (this should output the version of Python that you have):

python --version

DEMO - starting terminal DEMO - show Python version

on OSX and Windows:
- go to the Download section on python.org: http://python.org/download/
- scroll down to the list of files for Python 3.x (the version is in the file name, just get the latest)
- make sure you're looking at the 3.x files, not 2.x
- save the installer and run it
on Ubuntu:
- sudo apt-get install python3
- sudo apt-get install idle3

you can test your installation by opening terminal or cmd.exe (see the previous slide on checking Python version)
except, this time, you should have python 3 available, so use "python3" instead of the regular python interpreter: python3 –version
you can also try running IDLE
- OSX - ⌘-space → start typing idle → choose IDLE - Python 3.x
- Windows → Start → All Programs → Python 3.x → IDLE
