[mod_python] I don't know mod_python style programming.

I'm a mod_python beginner. 
Supposing that I'll make web bbsboard using mod_python. 
Maybe, general Web bbsboard is consist of post, delete, reply.. etc
function. 
Following my handler example. 
-------------------- 
def handler(req): 
  if req.uri == 'post.py': 
    import post 
    mypost = post.postclass 
    mypost.post(some data) 
            . 
            . 
  elif req.uri == 'delete.py': 
    import delete 
    mydelete = delete.deleteclass 
            . 
            . 
            . 
  return apache.OK 
------------------- 
expatiation) Each post.py, delete.py are my definition class module. 

Is my handler's source mod_python style? 

Addition, 
If It's be right, my dbconnection clause('import mysqldb') that where
locate in? 

Thanks
