It was pretty straightforward to map it into a namedtuple using the
links I provided. The only killer for me was that the struct module
doesn't return an entry for "padding" bytes. Which makes sense, but
threw me off for a good while as I tried to figure why my
tuple-creation was complaining about a missing parameter (fixed by
commenting out the "__unused" member of the namedtuple; could also
have kept it while changing the "20x" to "20c" in the struct
format-string)
The rest was just basic text manipulation in vim to convert the C
structs into Python code.
And despite what Bernd Nawothnig wrote:

it gave me the opportunity to learn about the internals of the utmp
format, something that has long been a curiosity ("it's a binary log,
not text, I wonder what all is in there? But I don't have real cause
to go poking around in there to learn the answer right now.") and this
gave me the push I needed to explore that.
Glad it helped.
