Question

我创建了一个游戏，它使用tkinter打开GUI。它有一个计时器，当计时器用完时我希望它清除GUI并有一条消息，例如：时间到了，你得分+得分。我已经能够制作一个在GUI上执行此操作的标签，但即使计时器不为0也只是停留在那里。这是源代码：

import tkinter
import random

colours = ['Red','Blue','Green','Pink','Black','Yellow','Orange','White','Purple','Brown']

score=0
timeleft=30
def startGame(event):
    if timeleft == 30:
        countdown()

    nextColour()

def nextColour():
    global score
    global timeleft

    if timeleft > 0:
    e.focus_set()

    if e.get().lower() == colours[1].lower():
        score += 1
    e.delete(0, tkinter.END)
    random.shuffle(colours)
    label.config(fg=str(colours[1]), text=str(colours[0]))
    scoreLabel.config(text="Score: " + str(score))

def countdown():
    global timeleft

    if timeleft > 0:
        timeleft -= 1
        timeLabel.config(text="Time left: " + str(timeleft))
        timeLabel.after(1000, countdown)
    if timeleft == 0:
        canvas.delete("all")
        endGame.config(text="Time up, you scored " + str(score))


root = tkinter.Tk()
root.title("TTCANTW")
root.geometry("375x250")

instructions = tkinter.Label(root, text="Type in the colour of the words,     and not the word text!", font=('ariel', 12))
instructions.pack()

endGame = tkinter.Label(root, text="Time up, you scored " + str(score), font=('ariel', 12))
endGame.pack()

scoreLabel = tkinter.Label(root, text="Press enter to start", font=   ('Helvetica', 12))
scoreLabel.pack()

timeLabel = tkinter.Label(root, text="Time left: " + str(timeleft), font=('Helvetica', 12))
timeLabel.pack()


label = tkinter.Label(root, font=('Helvetica', 60))
label.pack()


e = tkinter.Entry(root)

root.bind('<Return>', startGame)
e.pack()
e.focus_set()
root.mainloop()

你没有画布小部件，无法删除你必须使用destroy删除你想要删除的每个小部件.. 我编辑了你的功能

def countdown():
    global timeleft

    if timeleft > 0:
        timeleft -= 1
        timeLabel.config(text="Time left: " + str(timeleft))
        timeLabel.after(1000, countdown)

    if timeleft == 0:
        #canvas.delete("all")
        instructions.destroy()
        timeLabel.destroy()
        label.destroy()
        e.destroy()
        #-------------------------
        endGame.config(text="Time up, you scored " + str(score))

有没有办法清除画布，如果使用tkinter并使用不同的消息再次写入它？
