For this, you can use the sys.excepthook that allows us to attach a handler
for any unhandled exception:
#Creating a logger
logger = logging.getLogger(__name__)
logging.basicConfig(filename='example.log', filemode='w', level=logging.DEBUG)
#Creating a handler
def handle_unhandled_exception(exc_type, exc_value, exc_traceback):
if issubclass(exc_type, KeyboardInterrupt):
#Will call default excepthook
sys.__excepthook__(exc_type, exc_value, exc_traceback)
return
#Create a critical level log message with info from the except hook.
logger.critical("Unhandled exception", exc_info=(exc_type, exc_value, exc_traceback))
#Assign the excepthook to the handler
sys.excepthook = handle_unhandled_exception
First, you will create a logger that will take care of your exceptions.
Then create a handler handle_unhandled_exception that you will later attach to
the hook. Then call the __excepthook__ provided by the sys module. This
method is invoked every time the exception is uncaught.
Use the info from the hook to create a log message and assign this handler to
the sys.excepthook.
You can learn more info about sys.excepthook in
the offical documentation.
