What is the easiest way to install another Python version along side the default Python version?

I ran Ubuntu 10.0.4 LTS, which uses Python 2.6, and used Vagrant SSH to run and check my code in Python 2.6 (and I replaced a dict comprehension with a list comprehension, for example) > - ... > > What is the recommended way? I don't expect/hope that I'd ever need something lower than Python 2.5 I use pythonz: http://saghul.github.io/pythonz/ It lets me specify not just the version I want, but the implementation I want: I can install CPython 2.6.1, PyPy 2.0.2, and Jython 2.5.3 all the same way. -- Ned Batchelder, http://nedbatchelder.com
