Change python3 executable to another version

Question

Currently when I enter python3. It runs "python3.2.3" version but what I want is when I enter python3 on the shell is it should run "python3.5.1".

I am running on a Debian Wheezy OS

The instruction there is not clear besides it is on windows OS. I have a Debian Wheezy OS — Dean Christian Armada, Jan 20 '16 at 11:42
Which OS are you running? Which environment? Maybe provide a little more details? Otherwise your question reads as "How do I do a thing?" — Alexey Kamenskiy, Jan 20 '16 at 11:42

I would say you need to look at virtualenv. This is a common tool for having isolated Python environments.

I won't provide here an example as simple Google search for "use multiple versions of Python" provides enough detailed material.

On CentOS/redhat you can just link /usr/bin/python to you "python3.2.3" executable.

RPM package just duplicates this binary:

[~]# md5sum /usr/bin/python2.6
71494aa9082392bff9f93b725773ec39  /usr/bin/python2.6
[~]# md5sum /usr/bin/python
71494aa9082392bff9f93b725773ec39  /usr/bin/python

May be this help Install python 3.5, or you can also use ANACONDA
