use a slice
as a generic example you can try in the interactive interpreter (aka 
REPL):

>>>items = [1,2,3,4,5,6,7,8,9,0]
>>>for item in items[:-1]:
>>>    print(item)

I should state for the record that I am no Python expert, I mainly visit 
this news group to learn.
sometimes from reading solutions & somtimes by trying to work out what 
the solution might be.

most productively by working out a solution & seeing if other posters 
agree (& working out why they don't)
