How to pass a callback function when use obspython script

[1170300710]

I am try to use obspython.py in my python project.
I am confused that how to use the function in obspython.py like:

def signal_handler_connect_ref(handler: "signal_handler_t *", signal: "char const *", callback: "signal_callback_t", data: "void *"):`
    do_something....

I use these code:

signals = obs_output_get_signal_handler(self.m_output_repley)
signal_handler_connect_ref(
    signals,
    "saved",
    lambda a,b:print(123),
    None
)

it raise an error: "TypeError: in method 'signal_handler_connect_ref', argument 3 of type 'signal_callback_t'"

and I try these code too, but get same error:

def replay_saved_callback(param, data):
    print("asd")
signals = obs_output_get_signal_handler(self.m_output_repley)
signal_handler_connect_ref(
    signals,
    "saved",
    replay_saved_callback,
    None
)
