1、ListBox

import tkinter as tk
window = tk.Tk()
window.title("The window")
window.geometry("400x600")
#创建变量
var1 = tk.StringVar()
l = tk.Label(window,bg='red',width=10,textvariable=var1)
l.pack()
def print_selection():
    #获取当前选中的文本内容
    value = lb.get(lb.curselection())
    #为label的值设为value
    var1.set(value)
b1 = tk.Button(window,text='print selection',width=15,
               height=2,command=print_selection).pack()
var2 = tk.StringVar()
#为变量设置值，此处用元组
var2.set((11,12,13,14))
#创建Listbox,将var2的值赋给listbox
lb = tk.Listbox(window,listvariable=var2)
list_item = [1,2,3,4]
for item in list_item:
    #从列表控件最后一个为止加入值
    lb.insert('end',item)
#在第一个位置加入'first'字符
lb.insert(1,'first')
#在第二个位置加入'second'字符
lb.insert(2,'second')
#删除第二个位置的字符
lb.delete(2)
lb.pack()
window.mainloop()

import tkinter as tk
window = tk.Tk()
window.title("The window")

var = tk.StringVar()
#l = tk.Label(window,bg='red',width=30,text='empty').pack()
l = tk.Label(window,bg='red',width=30,text='empty')
l.pack()
def print_selection():
     l.config(text='you have selected ' + var.get())
#创建选项部件，当我们鼠标选中了其中一个选项，把value的值‘A'放到变量var中，再赋值给varilable
r1 = tk.Radiobutton(window,text='Option A',variable=var,value='A',command=print_selection)
r1.pack()
r2 = tk.Radiobutton(window,text='Option B',variable=var,value='B',command=print_selection)
r2.pack()
r3 = tk.Radiobutton(window,text='Option C',variable=var,value='C',command=print_selection)
r3.pack()
window.mainloop()
