In one of my own packages, I use the following to catch dynamic error
messages:
def handle_error(exc):
# do stuff with exc
with catch('error_code', handle_error):
# do stuff that can raise an error
The definition of "catch" is as follows, assuming the root exception
actually raised is called "CodedError" whose "code" attribute is the error
code:
from contextlib import contextmanager
@contextmanager
def catch(code=None, caught=None, always=None):
try:
yield
except CodedError as exc:
if isinstance(code, str):
is_caught = exc.code == code
else:
is_caught = exc.code in code #assume it's a container
if (code is not None) and not is_caught:
raise
if caught is not None:
caught(exc)
finally:
if always is not None:
always()
Perhaps you could make use of this?
Suggesting,
Ken Hilton;
