如何将参数传递给tkinter中的事件处理程序？

button = tkinter.Button(root, text="Click", command=lambda: event_handler(value))

import functools

button = tkinter.Button(root, text="Click", command=functools.partial(event_handler, value))

class MyWindow(tkinter.Tk):
    def __init__(self):
        tkinter.Tk.__init__(self)
        self.button = tkinter.Button(self, text="Click", command=self.event_handler)
        self.button.pack()

    def event_handler(self):
        # 使用self.value来获取传递的参数
        print(self.value)

window = MyWindow()
window.value = "Hello"
window.mainloop()
