Doch bekomm ich im Aufruf im Browser folgende Fehlermeldung:
und wenn ich das Programm mit meinem Debugger laufen lasse bekomme ich diese Meldung:Serverfehler!
Die Anfrage kann nicht beantwortet werden, da im Server ein interner Fehler aufgetreten ist.
Fehlermeldung:
Premature end of script headers: peoplecgi.py
Sofern Sie dies für eine Fehlfunktion des Servers halten, informieren Sie bitte den Webmaster hierüber.
