I started learning Python 3.4Python 3.4 and would like to start using libraries as well as Google App EngineGoogle App Engine, but the majority of PythonPython libraries only support Python 2.7Python 2.7 and the same with Google App EngineGoogle App Engine.
Should I learn 2.72.7 instead or is there an easier way? Is(Is it possible to have two2 Python versions on my machine at the same time?)
