I'm looking for a cheap hosting company (around australia they're pretty costly) in america that may host an internet site which has a domain that finishes with .internet.au, &lifier supportsOroperate python scripts.

Does anybody are conscious of any US web hosting companies that may do this stuff?

Any host must do, the domain title is something you wouldn't always acquire together with your host. Without having a website, acquire one.

After that, simply discover the host that meets your requirements (bandwidth, storage, reliability), then you'll point your domain title for your hosts nameservers. You can opt for something simple like Godaddy (http://world wide web.godaddy.com/hosting/web-hosting.aspx) or something like that modern-day like Rackspace (http://world wide web.rackspace.com/handled_hosting/index.php).

Hosting price varies. The price is affected by a few factors, including reliability, shared/private atmosphere, bandwidth (both readily available for use and actual usage), and machine hardware specs, etc...
