I actually thought that the sys.excepthook would be easy but it's not
so trivial apparently:
This simple sample never reaches the print("here"), because even if
the exception is catched it still quits with return code=1.

I also tried to catch the signal but same result, how do I make it
continue and just don't complain?

The other option if of course to do a big try/except, but I would
prefer the excepthook solution..


import sys
from shutil import copy

def my_except_hook(etype, value, tb):
    print("got an exception of type", etype)


if __name__ == '__main__':
    sys.excepthook = my_except_hook
    copy('sdflsdk')
    print("here")
