Multiple versions of Python

Question asked by gsinkinson on Nov 5, 2014

I'm looking for recommendations on how to handle multiple versions of Python on a single machine.

 

I have ArcGIS 10.2.1 for Desktop installed on a Windows 8.1 machine.

The installation of ArcGIS set up Python in C:\Python27\ArcGIS10.2.

The Readme indicates this is Python version 2.7.5

 

I'd like to use Python version 3.4.2 for some non-ArcGIS applications.
I'm assuming the install would set up in something like C:\Python34

 

I'm looking for help on several things:

     - some rational directory structure approach and naming
     - what to do with the scripts in C:\Python27\ArcGIS10.2\Tools

 

I don't want to compromise the ability to use Python with ArcGIS but
I don't have any idea if all the version 2 scripts are still valid in version 3.

 

I don't know if I need to keep both versions, but if so, how would I control
which version is invoked? Currently there isn't any Python entry in my
PATH statement.

 

Yes, obviously a 'newbie', but I'd like to start off in the right direction ...
