Just a quick shoutout to PythonAnywhere! I have been tinkering with some Python code for a web app and needed to set up Django or web2py, but didn't want to modify a live server or set up an additonal server solely for testing. I signed up for the free service, and was able to easily choose a version of python, add modules, set up a Mysql database or a run cron job. I added web2py in less than 30 seconds, with one eye on the game, in comparison to the grief I would have encountered setting it up on a shared server. For my needs, I found it perfect for running a small test environment and it is highly recommended.
