Just to have in the thread (though the OP seems to be using 2.6 
or later), the bin() function appears to have been added in 2.6 
which is something I wish had been back-ported to 2.4 and 2.5 as 
I've been sufficiently stuck coding against older versions of 
Python to have (re)written a bin() function multiple times.  Ah well.
