      Updates a component's properties. When a function passed into a Gradio Interface or a Blocks events returns a value, it typically updates the value of the output component. But it is also possible to update the *properties* of an output component (such as the number of lines of a `Textbox` or the visibility of an `Row`) by returning a component and passing in the parameters to update in the constructor of the component. Alternatively, you can return `gr.update(...)` with any arbitrary parameters to update. (This is useful as a shorthand or if the same function can be called with different components to update.)
  
      Parameters:
          elem_id: Use this to update the id of the component in the HTML DOM
          elem_classes: Use this to update the classes of the component in the HTML DOM
          visible: Use this to update the visibility of the component
          kwargs: Any other keyword arguments to update the component's properties.
      Example:
          import gradio as gr
          with gr.Blocks() as demo:
              radio = gr.Radio([1, 2, 4], label="Set the value of the number")
              number = gr.Number(value=2, interactive=True)
              radio.change(fn=lambda value: gr.update(value=value), inputs=radio, outputs=number)
          demo.launch()
      """
