How to catch and print the full exception traceback without halting/exiting the program?

Question

I want to catch and log exceptions without exiting, e.g.,

try:
    do_stuff()
except Exception, err:
    print(Exception, err)
    # I want to print the entir

This is my solution to write the error in a log file and also on console:

import logging, sys
import traceback
logging.basicConfig(filename='error.log', level=logging.DEBUG)

def handle_exception(exc_type, exc_value, exc_traceback):
    import sys
    if issubclass(exc_type, KeyboardInterrupt):
        sys.__excepthook__(exc_type, exc_value, exc_traceback)
        return
    exc_info=(exc_type, exc_value, exc_traceback)
    logging.critical("\nDate:" + str(datetime.datetime.now()), exc_info=(exc_type, exc_value, exc_traceback))
    print("An error occured, check error.log to see the error details")
    traceback.print_exception(*exc_info)


sys.excepthook = handle_exception
