Question

我有这个：

if fn is not None:
    print('ok we are running the func')
    fn(d.error, d)
    print('ok we ran the func')
    return

我注销了：

ok we are running the func

我登录它时，fn对象如下所示：

here is fn: <function LMXClient.make_lock_acquired.<locals>.on_lock_acquired at 0x7f344f97c488>

定义如下：

def make_lock_acquired(self,cb):
    print('lock was acquired.')

有人知道我为什么不能打电话吗？没有try / catch，所以据我所知，错误不会被吞没。

更新：是的，当我明确包装try / catch

时，Python吞下了错误或其他内容。

       try:
            fn()
        except:
            print("Unexpected error:", sys.exc_info()[0])

然后我收到此错误：

Unexpected error: (<class 'TypeError'>, TypeError("make_lock_acquired() missing 1 required positional argument: 'cb'",), <traceback object at 0x7f0cf873ccc8>)

不确定为什么

fn不是None，但我无法执行
