The only real difference is coding style and the formatting options of
the %s way that I can see.
%s is negligibly slower in my tests, but we're talking the tiniest
fraction of a second over thousands of iterations, not worth considering...

On the other hand, if it is nearer the end of the set of keys would it
not be slower?
Does this make it more dependent on the search order whether a list or
a dict is faster? Or am I completely on the wrong track?

timed it to show the speed difference.
Can anybody please step in and correct us?

A famous Holden typo - it should have been 12 * 256 == 3072, but
really it shouldn't have been beyond you to perform a division of 3072

involved).
Basically the value you want is shifted up 8
ok, I was thinking of shifting using subprocess, guess I'd better do

problem with that is that the path may change between installations on

I know that isn't portable which is why a python solution would be
