I have python 2.7 installed globally on my machine - Mac OSX. I tried have installed python 3.5 just by downloading the file but haven't changed PYTHONPATH / any PATH variables as I was not sure what to do. I am now running a virtualenv in which python 3.5 is installed. But when I try to run any modules I wrote, it says "ImportError: No module named XYZ". It is running fine when I am out of the virtualenv.
Is this because of PYTHONPATH ? if so, what changes need to be made. Also can anyone point me to a tutorial on how to install python 3.5 and make it running fully functional?
