It seems that the rationale that was used in the PEP was fairly
narrowly focused on the comparison with things like dict.get() and the
idea of EAFP. A somewhat broader justification might be something along
these lines:
For an example. Anyone is free to use, but I'm not claiming it's necessarily the best. This is from... well, probably not yesterday like I said in other comment, but a couple days ago. The module `jsonschema` has an API where it raises an exception if `validate()` doesn't succeed (None if things are happy). I don't love that API, so want to wrap it.
def not_valid(instance, schema):
try:
return validate(instance, schema)
except ValidationError as err:
return str(err)
I really wanted that to be one line rather than a helper function, and it really feels like it should be possible... and yet.
The dead increasingly dominate and strangle both the living and the
not-yet born. Vampiric capital and undead corporate persons abuse
the lives and control the thoughts of homo faber. Ideas, once born,
become abortifacients against new conceptions.
