So I picked a bad example. Sorry. Someone (sorry, I can't recall who)
did ask for

>>> print(' '.join("{:02x}".format(c) for c in b'Abc'))
41 62 63

My point is that a simple pattern is flexible, a specific method has
to pick one "obvious" representation, and there have been a number of
representations discussed here.
