Python Anywhere...

everywhere, everywhere, pythonist' everywhere... (pythonanywhere.com)

You can choose between some consoles for work:

Python: 2.7, 2.6, 3.2
Ipython: 2.7, 2.6, 3.2
PyPy:    2.7
Bash
Mysql... they have plans to include Mongo, and you can tell them, that you need it :D .
You can share them(the consoles) :) .

(extra)Modules:

Django, CherryPy, Flask, Bottle, web.py...
You have easy_install and pip instaled.
And if you need more, yes, you can say them.

Files:

You have a unix like filesystem, thats mean that you count with a /home, /var/www/.
You cloud upload your files.
You can sync whit dropbox and git... It's supossed that you can edit files whit VIM and
Emacs, you have a .vimrc (of course in your /home) and a bashrc.

You have a subdomain:

http://r_ascencio.pythonanywhere.com/
500M
Dropbox and Git sync.


So if you listen about django, web.py, python and you can start to discover it, make you projects, try your projects, see how it would be in Django... without installed in your computer...
