I just looked at the PEP. Great job!
However:
the "elif" option should have a colon after it,
and "elif" should be added as an option to the
"then-else" variant.
I like the first two about equally (especially if
an elif was added, which is not possible with
the last one. Each has a flaw, though. I'd go
with whichever option appeals to the BDFL
and the rest of the community.
I don't like the last two options.
