每个回调将被调用一次。 Any positional arguments after the callback will be passed to the callback when it is called. 回调后的任何位置参数都会在调用时传递给回调。 An optional keyword-only context argument allows specifying a custom contextvars.Context for the callback to run in. The current cont...
在需要注册回调函数的场景中 ,如事件处理、异步编程等,使用*args与**kwargs可以让回调函数适应各种调用者的参数需求: def generic_callback(*args, **kwargs): print(f"Received callback with args: {args} and kwargs: {kwargs}") button.on_click(generic_callback) # 无论按钮点击事件如何传递参数,该...
