I need it to output as 0x0a, and the exercise is requiring

Though it feels hokey to me, using
"%#04x" % 10
works for me.
I think "0x%02x" % 10 is a bit more readable, but it accomplishes the
same thing -- you just don't have to do the mental math to add the
prefix width to the number of desired hex digits in the output.
Which, I confess, is what I usually use because I didn't know
about the "#" until this thread, and just made the assumption
that one can get the zero-padding along with the "alternate form"
in my experimentation this afternoon.
So while it _can_ be done with just variants of the "%x"
place-holder (as suggested by the OP's exercise), at least two of
us on the list prefer to explicitly add the "0x" to the beginning.
