With Python 3, the following code will format an Exception
object exactly as would be obtained using traceback.format_exc()
:
import traceback
try:
method_that_can_raise_an_exception(params)
except Exception as ex:
print(''.join(traceback.format_exception(etype=type(ex), value=ex, tb=ex.__traceback__)))
The advantage being that only the Exception
object is needed (thanks to the recorded __traceback__
attribute), and can therefore be more easily passed as an argument to another function for further processing.
