tkinter radiobutton实例

以下是一个tkinter Radiobutton的实例：

import tkinter as tk

window = tk.Tk()
window.title("Radiobutton Example")

var = tk.StringVar()
var.set("Option 1")

def print_selection():
    label.config(text="You have selected " + var.get())

rb1 = tk.Radiobutton(window, text="Option 1", variable=var, value="Option 1", command=print_selection)
rb1.pack()

rb2 = tk.Radiobutton(window, text="Option 2", variable=var, value="Option 2", command=print_selection)
rb2.pack()

rb3 = tk.Radiobutton(window, text="Option 3", variable=var, value="Option 3", command=print_selection)
rb3.pack()

label = tk.Label(window, text="")
label.pack()

window.mainloop()

这个例子创建了一个窗口，其中包含三个Radiobutton选项，当用户选择其中一个选项时，程序会在窗口中显示所选选项的文本。
