Why not just put
try:
...
except:
...
around the main function?
That said, it looks like you can exit() from the errorhandler:
$ cat bend_exit.py
import sys
def my_error_handler(etype, exception, traceback):
print("unhandled", exception)
sys.exit(2)
sys.excepthook = my_error_handler
1/int(sys.argv[1])
print("bye")
$ python3 bend_exit.py 0; echo $?
unhandled division by zero
2
$ python3 bend_exit.py 1; echo $?
bye
0
If "bad things" can happen I don't know...
