Few Small Questions Regarding CGI

[joy99]

Dear Group,

I am trying to learn CGI. I was checking Python Docs. There are
multiple modules. Which one to start with?
Is there any other material or URL for step by step learning of CGI.

My next question is:
I want to test it. I have a small personal computer. I have internet
but is connected by a service provider. I do not have personal web
page. Can I use my personal computer as a client as well as a server?

If your kind time permits to answer me these questions, I would be
hugely benefited.
Wishing you a happy day ahead,
Best Regards,
Subhabrata.
