deco1:

```
def deco(func):
    def wrapper(*args, **kwargs):
        f = func(*args, **kwargs)
        print("deco success")
        return f

return wrapper

```

deco2:

```
def deal_exc(func):
    def wrapper(*arg, **kwargs):
        try:
             return func(*arg, **kwargs)
        except Exception as e:
             print(str(e))

    return wrapper

```

use decos:

```
@deal_exc
@deco
def a_function():
    print(0 / 100)
    raise Exception("666")

```

how to skip `print("deco success")` when i raise an exception and let `deal_exc` decorator deal with the exception?
