Python 带Tkinter按钮命令的hel

我试图在tkinter上创建一个应用程序，但我遇到了一些问题。所以问题在于启动按钮，当按下时，它必须在屏幕上显示结果，但我不知道应该在命令行中写入什么才能使其工作。我尝试了类似于

command=game（answ）

的方法，但这不起作用，因为当你启动程序时，它已经显示了结果，所以启动按钮没有意义。我能做什么？下面是游戏没有参数的代码，所以它不起作用

def asking():
    global win, win2, answ, bbok
    answ = simpledialog.askinteger("input string", " Choose 1 / 2")
    if answ == 1 or answ == 2:
        win2 = tk.Toplevel()
        win2.wm_title("Great Choice")
        bbok = tk.Button(win2, text=f'Selected {answ}', command=goback2)
        bbok.pack()
        root2.destroy()
    else:
        win = tk.Toplevel()
        win.wm_title("Error")
        bok = tk.Button(win, text="Try Again! Insert other value", command=goback)

B1.pack(expand=1)

root2.mainloop()



root = tk.Tk()
root.title(f'Russian Roullete {version}')

canvas = tk.Canvas(root, height=800, width=700, bg="#FF5733")
canvas.pack()

mainframe = tk.Frame(root, bg="grey")
mainframe.place(relwidth=0.3, relheight=0.1, relx=0.6, rely=0.8)

start = tk.Button(mainframe, text=" Start !", padx=60, pady=20, fg="black", bg='grey', command= game(answ))
start.pack(expand=1)

frame_count = tk.Frame(root, bg="grey")
frame_count.place(relwidth=0.16, relheight=0.05, relx=0.675, rely=0.72)




for x in a:
    moves = tk.Label(frame_count, text=f'Number of moves {x}', bg='grey')
    moves.pack(expand=1)

root.mainloop()

print(f'Me {count_w} :  {count_l} Enemy')```

当你设定

command = game(answ)

它立即调用

game

，并传递返回值（返回值为

None

），而不是函数本身。如果必须传递参数，请使用lambda函数，如下所示：

command=lambda:game（answ）

谢谢你帮助我。现在我有另一个问题：）我在函数中创建了一个标签，现在当我打包它时（我的程序有一个选项可以运行无限时间（它可以重新启动）），它会显示上一次运行的结果，我能以某种方式修复它吗？
