We are going to install Python version 2.7.5.
We are going to install Python version 3.4.1.


If you already have Python installed, check the Python version: if the version is between Python 2.5 and Python 2.7, you can use it for this class and can skip to [[Windows_set_up_Python#Put_Python_on_the_PATH|setting your Path]].
If you already have Python installed, check the Python version: if the version number starts with a 3 (as opposed to a 2), you can use it for this class and can skip to [[Windows_set_up_Python#Put_Python_on_the_PATH|setting your Path]].
