Or even (still being my favorite):

This syntax actually has a benefit: the parenthesized syntax after
except could become a list, to allow handling different exceptions
from the tried expression with different results:
msg = seq[dictionary[i]] except (IndexError: "nothing", KeyError:
"serious problems")
It shouldn't be a true list. We need lazy evaluation of the default
values. And if an unlisted exception is raised, we don't want any of
the defaults evaluated.

And still allows nesting:
msg = seq[i] except (IndexError: dictionary[i] except (KeyError: "no
fallback data for %s" % i))
