There are many web frameworks and tools for interacting with databases 
on the web. Try a look through the just over eight million hits in

    http://www.google.com/search?hl=en&lr=&q=python+web+database

(hint: the first two or three pages will be the best. Look for books by 
people whose names seem familiar :-).

Some of those links will contain real examples of code and give you a 
useful idea of how some things can be done. Others will doubtless post 
more specific advice, so I am trying to provide a little background in 
case it should be needed.

More specific (Google) searches will also give insights into different 
aspects of this problem.

regards
  Steve
