Some more about error handling. This time as decorator to "protect" functions:

def no_err(f):
    def _f():
        try:
            f()
        except Exception as err:
            pass
    return(_f)


@no_err
def test(*args, **kwargs):
    a = 3
    print(a) # ok
    print(a + b) # generates error
    print("unreachable because of error")
