Hmmm, well, I won't categorically say you *must* use a function, but I
will say that using a function is probably the best solution.

If you nest your function inside the major function, you don't even need
to pass arguments:


     def function(a, b, c, d, e):
         # More local variables:
         f, g, h = 1, 2, 3
         
         def inner():
             # all locals a...h are visible in here
             return result

         thing = inner()


so you may be able to move your processing to an inner function, without
needing to explicit pass any arguments to it, and make use of return,
rather than adding a loop so you can use break.


Thank you - good suggestion.  (Except for apps which are 
performance-critical where I would expect defining a function each time 
the major function is called to have significant overhead.  My apps 
usually aren't.)
