Ha! Now we are talking style! :-)
Yes, that's, of course, an option also, but we are moving away from the 
original question and I feel guilty already wasting this forums' reader 
time with my trival question...

My main reason not to use function in this case, is that it may result in 
moving meaning full code too far away from where the action is. However, 
after reading some things on the web, I can solve this by added nested 
functions:

def BigFunction: 

    < lots of code > 

    def DefaultForLoopCode():
        pass

    for a in myList[:-1]:
        DefaultForLoopCode()
    DoExtra()
    DefaultForLoopCode()
    
I think this will solve my problem, while still keeping everything 
relatively clean. 

Thanks,
Tom
