I started learning
Python 3.4
and would like to start using libraries as well as
Google App Engine
, but the majority of
Python
libraries only support
Python 2.7
and the same with
Google App Engine
.
Should I learn
2.7
instead or is there an easier way? (Is it possible to have 2 Python versions on my machine at the same time?)
Answers
No, It doesn't.

Google App Engine
(GAE)
uses sandboxed
Python 2.7
runtime for
Python
applications. That is the normal
App Engine Hosting
. However, in
GAE
you can use
Managed VM Hosting
.
The
Managed VM Hosting
lets you run
GAE
applications on configurable
Google Compute Engine Virtual Machines
. Giving you more flexibility.
Managed VMs
at the moment ,at Alpha phase, only support
Java 7
,
Python 2.7
and
Go 1.4
runtime environments. To get other runtimes (like
Python 3
or
node.js
) you can create user-configurable custom runtime.
Note:
With
Managed VM
s you won't have the capabilities of
Python 2.7
GAE
libraries.
If you insist on using
GAE
, since
Python 3+
is not viable, I would suggest learning
2.7
and switching to
3+
versions when
GAE
libraries gets ported to
Python 3+
. You can easily switch to the other if you learn one of the versions.
If you insist on using
Python 3+
, you can use
Heroku
or
Microsoft Azure
. Both of them supports
Python 2.7
and
3.4
.
