Let me try that again (for some, my cancel will have worked, soon 
enough, and you'll think "*again?".  Starting with Python 1.6, we can say
myList.append( (functionA(), funcationB(), functionC(), 
functionD(),functionD()) )

But unfortunately that's not friendly now: it appends the tuple as one 
item:

>>> a = []
>>> a.append((1, 2, 3))
>>> a
[(1, 2, 3)]


To work with 1.5.2 and 1.6, the loop would need to be something like

     for i in range( 10 ):
        myList.append( functionA() )
        myList.append( functionB() )
        myList.append( functionC() )
        myList.append( functionD() )
        myList.append( functionE() )

Perhaps with a comment suggesting the single append for some future time 
when 1.5.2 and earlier versions do no matter.
