I agree. I would rather call func() only once per iteration in any

I am pretty sure that the sorted() construct cannot be improved much
further, but...
...does anyone have ideas on improving the "rawPairs" iterator so that
it calls "func(s)" only once per iteration? Perhaps a lambda
construct, but I am not sure how to go about it...?

Cool, thanks for posting this example and clearing that up. Several
times in the past I have used super(self.__class__, cls) instead of
super(Klass_obj, cls), without a clue that it would wreck the
subclasses. My beginner's thought at the time was that it would
provide more flexibility.. Good thing I haven't had to subclass
them..yet :)

Have you tried GUI2Exe? I've found its interface quite easy to use.
It doesn't recurse into a dir tree (feature request?), but it makes
the selection process at leas
just nice how it works that way.
Otherwise, the function factory approach like Hrvoje's

in your case the 3 fixes above will allow you now to do this:

Try wxPython. I've seen it run on a Mac with OS X and Windows
simultaneously, where the operating systems were switched from one to
the other at the touch of a button, and the GUI had a very native look
in either platform (mind you, the app was running exactly

the above function should be a method of a class that inherits from
the appropriate handler class? Any help will be appreciated.

It's a presumption based on the original problem statement.
The example shown is a simple T/F check, which happens to determine
the "emptiness" of strings.
If type checking is absolutely necessary, one could use
if isinstance(s, basestring):
if s:
A simple
if s:
print "not empty"

print "empty"
