How can I install extra versions of python on Debian (jessie). On Ubuntu I can use the "deadsnakes" PPA which will give me any python version I want, with the version name in the command (e.g.
python33 for python 3.3). This allows me to install them all beside each other. I can use virtualenvs to install specific python packages for specific versions without messing with the system packages. I maintain some python libraries, and they need to work on many versions of python. If I have the python binary installed, then tox will take care of using virtualenvs for each python version.
So what's the debian equivalent of Ubuntu's deadsnakes PPA?
UPDATE I want to install python: 2.6, 2.7, 3.3, 3.4 and 3.5.
