i found this one is a good deal for me :-) what about this:

if db_first:
  db_flag = "w";
else:
  db_flag = "a";

is there a better way to write this? 

once again ... i don't want annoy you, i just start to learn python. 
Mainly i will use it for cgi programming. so the first thing i do is to 
write a simple guestbook. i was surprised how easy it was ... 

sorry for my bad english but i'm from germany :-)


So long ...
