Probles parsing a text file

[greg]

thanks Miki.

what would you suggest
somthing like
if line[:8] == "setVar1":
    #do somthing
elif line[:8] == "setVar2":
    #do somthing else
but this would be extreamly slow if there server.cfg has many directives in
it
then when the last directive is found (eg: setVar117) and this is the 116th
elif
then it will have to check through
if line[:8] == "setVar1":
    #do somthing
elif line[:8] == "setVar2":
    #do somthing else
elif line[:8] == "setVar3":
    #do somthing
elif line[:8] == "setVar4":
    #do somthing else
elif line[:8] == "setVar5":
    #do somthing
...............
..........
.....
elif line[:8] == "setVar117":
    #execute code for 117

what do you think
