Hey everyone

I am learning Python as I have been told that it is a reletively easy language to start learning basic game design. However, I am having trouble with conflicting versions of python as some tutorials support .3 and others .2 so I have downloaded both versions, but now I cannot figure out how to change from my default version 2.7.3 to 3 and vise versa.

I have tried typing the following in my Python shell - c:\python33\python.exe and /user/local/bin/python-3 but both return errors. Both my python versions are on the C:\ drive. I have been told that a virtual environment is a possible way round this but I would much rather keep it simple and know what the syntax is to just change versions.

Many thanks
Simon

You may want to do a search on setting environmental variables in Windows or whatever you are using. If you are familiar with the command line then you can use:

set PYTHONPATH=%PYTHONPATH%;C:\My_python_library
which will set the path for only that session. You could make a little batch file so you wouldn’t have to type it each time.
