在pythontkinter中，我想创建一个按钮disapear并运行defin

Question

我有代码，将高兴地删除按钮后，按下它，或将运行代码，但我不能让它做这两个。我想知道是否有什么办法来做这件事。你知道吗

import tkinter
window = tkinter.Tk()

def start():
gamestart = True
#this runs the code at the end

#btn = tkinter.Button(window, text = 'Prepare to fight' , command = start)
#this would create a button that runs the code(but not perfectly)
btn = tkinter.Button(window, text="Prepare to Fight", command=lambda: btn.pack_forget())
#this creates a button that dissapears
btn.pack()
#creates button
window.mainloop()
if gamestart == True:
    lbl = tkinter.Label(window, text = 'WELCOME TO PYTHON COMBAT')
    #beggining of game

如果您只想使用command来执行definition，同时删除button，那么您只需要调用command，它删除button，并执行您需要的任何代码段。你知道吗

这只需要正确使用lambda就可以将包含button的变量传递给definition，如下所示：

from tkinter import *

root = Tk()

def command(button):
    button.pack_forget()
    print("Command executed and button removed")

button = Button(root, text="Ok", command=lambda:command(button))

button.pack()

root.mainloop()

上面的只会“隐藏”这个button意思是你可以pack以后再这样做，下面的会完全删除button：

from tkinter import *

root = Tk()

def command(button):
    button.destroy()
    print("Command executed and button removed")

button = Button(root, text="Ok", command=lambda:command(button))

button.pack()

root.mainloop()
