在python tkinter中，我想做一個按鈕disapear，並運行一個定義

Question

我有代碼，它會很高興地刪除按鈕後，它將被按下，或將運行代碼，但我不能使它們都做。我想知道是否有這樣做。

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

如果你想要做的是使用command執行definition，也拆除button，那麼你只需要簡單地調用command其去除button，同時執行任何代碼段，你需要它。

這僅僅需要正確使用lambda，讓您可以通過其中包含button到definition變量，就像下面：

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() 

---

以上只會「隱藏」的button意義你可以pack它再次後，下面將完全刪除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()
