尝试用tkinter观察两个IntVar并挑选最小的数字

import tkinter as tk
from tkinter import IntVar

window = tk.Tk()
window.title("观察IntVar并挑选最小的数字")

var1 = IntVar()
var2 = IntVar()
var1.set(10)
var2.set(20)

label1 = tk.Label(window, textvariable=var1)
label1.pack()

label2 = tk.Label(window, textvariable=var2)
label2.pack()

def compare():
    min_value = min(var1.get(), var2.get())
    result_label.config(text="最小值为：" + str(min_value))

compare_button = tk.Button(window, text="比较", command=compare)
compare_button.pack()

result_label = tk.Label(window, text="最小值为：")
result_label.pack()

window.mainloop()
