Adding function to sys.excepthook

Question

Say I have something like this, which sends unhanded exceptions to logging.critical():

import sys

def register_handler():
    orig_excepthook =         


        

Answer 1

You should use sys.__excepthook__[1].
It is an object that contains the original values of sys.excepthook[2] at the start of the program.
ie;

import sys
import logging

def register_handler():
    log = logging.getLogger(__name__)
    def error_catcher(*exc_info):
        log.critical("Unhandled exception", exc_info=exc_info)
        sys.__excepthook__(*exc_info)

    sys.excepthook = error_catcher
