python如何实现多个图片显示在屏幕上？
from tkinter import *

root = Tk()
# 创建一个Canvas，设置其背景色为白色 
cv = Canvas(root, bg = 'white', width = 500, height = 650)
rt = cv.create_rectangle(10,10,110,110,outline='red',stipple='gray12',fill='green')
for i in range(0,3):
print(i)
img=PhotoImage(file='D:\\python\\bmp\\'+str(i)+'.gif')
cv.create_image((20*i,200*i),image=img)
cv.pack()
root.mainloop()
只能显示2.gif ，前面0.gif，1.gif都不显示出来，为什么？

引用

image= The image object. This should be a PhotoImage or BitmapImage, or a compatible object (such as the PIL PhotoImage). The application must keep a reference to the image object.

from tkinter import *
 
root = Tk()
cv = Canvas(root, bg = 'white', width = 500, height = 650) 
rt = cv.create_rectangle(10,10,110,110,outline='red',stipple='gray12',fill='green')
imgs= [PhotoImage(file='/tmp/'+str(i)+'.gif') for i in range(3)]
for img in imgs:
   cv.create_image((20*i,200*i),image=img) 
cv.pack()
root.mainloop() 

另外, 也许你知道:

'D:\\python\\bmp\\'

可以用"raw string":

r'D:\python\bmp\'

即使是在windows下,也可以用

'D:/python/bmp/'

太感谢了！！！

怎么提示错误呢 cv.create_image((20*i,200*i),image=img) NameError: name 'i' is not defined
