Free python server.

[Kartic]

You can try for a free shell access at www.arbornet.org.

telnet (or better SSH) to m-net.arbornet.org and at the login prompt,
type newuser, press enter and follow the on-screen instructions to
register.

Once you register, you get a shell account with email and web space.
Since it is a free service, space is very limited but should more than
serve your needs now.
