This works great in 2.6.5 and later (and probably earlier). You just
have to number your placeholders. The first set of braces formats i
(your value), the second set specifies the field with (i.e., 8):

You're right, I use Python 2.6.6

You don't need the str() there as bin() already returns a number.
Here's a relatively trivial simplification - although it does make the
code more cryptic

You don't need to convert anything. The bitwise ops are &, |, <<, >>
0 | 2 | 4

unfortunately there is no builtin function for this
