如何在Python中从屏幕上删除Zelle图形文本？

Question

我想删除以图形方式显示的文字，这样我就可以编写新文本而不会重叠。我在下面提供了我的代码。再次感谢您的时间。

from graphics import*
import random

# Function for winning
def youwin():
    txt = Text(Point(250,100), "You are a Winner!")
    txt.setTextColor(color_rgb(0,255,200))
    txt.setSize(30)
    txt.setFace('courier')
    txt.draw(win)

# Function for losing    
def youlose():

txt= Text(Point(250,100), "You are a Loser!")
txt.setTextColor(color_rgb(0,255,0))
txt.setSize(30)
txt.setFace('courier')
txt.draw(win)


# Sets a Window
win = GraphWin("My Window", 800, 600)
win.setBackground('White')

# loops 10 Times and picks out 3 random gif's.
# Then displays each image on the screen in a row.

for x in range(10):

cards = ["1.png","2.png","3.png"]
rand_card1 = random.choice(cards)      
img1 = Image(Point(100, 250), rand_card1)
rand_card2 = random.choice(cards)
img2 = Image(Point(300, 250), rand_card2)
rand_card3 = random.choice(cards)
img3 = Image(Point(500, 250), rand_card3)


img1.draw(win) 
img2.draw(win)
img3.draw(win)

# checks to see if you are a winner

if rand_card1 == rand_card2 and rand_card2 == rand_card3:
    youwin()
else:
    youlose()


# waits for a mouse click.  In the future this will be a button.    
win.getMouse()    
img1.undraw()
img2.undraw()
img3.undraw()



#win.close()#    

这是我目前获得的输出：

Answer 1

我想你可能想以某种方式清除你的绘图区域，然后再在那里绘制新文本。一种方法是在旧文本上绘制一个与背景颜色相同的矩形。

我想删除我以图形方式显示的文字，以便我可以   写新文字

唐＆＃39;吨。您可以通过setText()重复使用文本对象。一个简单的例子：

import time  # just for demonstration
from graphics import *

win = GraphWin("My Window", 800, 600)

txt = Text(Point(250,100), "You are a Loser!")
txt.setSize(30)
txt.draw(win)

time.sleep(3)

txt.setText("You are a Winner!")

time.sleep(3)

如果您希望文字一段时间消失，只需txt.setText('')，直到您再次需要它为止。
