No idea what you mean here. I'll assume you're talking about the
version you DON'T quote here, the one with the if statements in the
except clause.

Yes, it has that advantage. Of course it doesn't USE that advantage for
anything so I'd go back to the pass version quoted immediately above.
Or I'd have two separate try/except clauses, one for each function call.
After all, the implication of the failure is different for each.
