如何实现Tkinter按钮点击后自动销毁？（附概率游戏代码）

要实现点击任意按钮后所有按钮立即隐藏，核心是保存所有按钮的引用，这样才能批量操作它们的显示状态。以下是具体修改方案：

关键修改点 #

• 新增全局列表存储所有按钮实例，避免创建按钮时覆盖变量
• 在按钮点击后的逻辑中，遍历列表调用place_forget()隐藏所有按钮
• 补充调用Start()函数，确保按钮正常显示

修改后的完整代码 #

from tkinter import *
from tkinter import messagebox
import random

point = 0
buttons = []  # 新增全局列表存储所有按钮

def showerror():
    messagebox.showerror("Loser","Next time :)")
    messagebox.showinfo("Your point", "Point: " + str(point))

def addpoint():
    global point
    point +=  31

def deleteButton():
    pass

def test():
    r = random.randint(0,7)
    if r > 4:
        showerror()
    elif r <= 4:
        addpoint()
    # 遍历所有按钮，调用place_forget()隐藏
    for btn in buttons:
        btn.place_forget()

tk = Tk()
tk.title("Are u Lucky")
tk.geometry("400x300")

def Start():
    P1 = Label(tk, text="Choose")
    P1.place(x=157,y=10)
    # 批量创建按钮并添加到列表
    positions = [
        (10,30), (50,30), (90,30), (130,30), (170,30),
        (210,30), (250,30), (290,30), (330,30), (370,30),
        (10,60), (50,60), (90,60), (130,60), (170,60),
        (210,60), (250,60), (290,60), (330,60), (370,60),
        (10,90), (50,90), (90,90), (130,90), (170,90),
        (210,90), (250,90), (290,90), (330,90), (370,90),
        (10,120), (50,120), (90,120), (130,120), (170,120),
        (210,120), (250,120), (290,120), (330,120), (370,120),
        (10,150), (50,150), (90,150), (130,150), (170,150),
        (210,150), (250,150), (290,150), (330,150), (370,150)
    ]
    for x, y in positions:
        btn = Button(tk, text="  X   ", command=test)
        btn.place(x=x, y=y)
        buttons.append(btn)  # 将按钮添加到全局列表

Start()  # 调用Start创建按钮

tk.mainloop()

补充说明 #

• place_forget()只是隐藏按钮，后续还可以通过place()重新显示；如果要彻底销毁按钮，改用btn.destroy()即可
• 把所有按钮位置整理成列表，简化了原代码的重复创建逻辑，更易维护
