Tkinter 无法打开多张照片

Question

Hello I am trying to open multiple tinker images. But when the first image loads up it stops the rest of the code from running please help.

Here is my code

from tkinter import *
from PIL import ImageTk, Image

root = Tk()

canvas=Canvas(root,width=420,height=560)
image= ImageTk.PhotoImage(Image.open("C:\Users\photo.jpg"))
root.geometry("420x560+0+0")

canvas.create_image(0,0, image= image, anchor=NW)
canvas.pack()
root.overrideredirect(1)

root = Tk()

canvas=Canvas(root,width=420,height=560)
image2= ImageTk.PhotoImage(Image.open("C:\Users\photo.jpg"))
root.geometry("420x560+77+77")

canvas.create_image(0,0, image= image2, anchor=NW)
canvas.pack()
root.overrideredirect(1)

root.mainloop()

I can not run this code in my computer,but just see your code.

You have used root = Tk() in line 4. Then you also use root = Tk() in line 14.

And when you use mainloop() in your code.it will mainloop the Tk() instance in line 14.Because the first Tk() has been covered.

There are two solutions:

1. If you want to show two windows at the same time.Use .after in the first Tk() instance and call a function to show another picture in a Toplevel() instance(Don't use many Tk() instance at the same time.It maybe will bring some bugs).
2. Or you want to show it in the same window,Just use .grid() (or others) to place them in the place of the window where you want.

A easy example for .after() to show more than two windows:

from tkinter import *
from PIL import ImageTk,Image

def ShowAnotherWin(i):
    win = Toplevel()
    win.title('Show')
    image= ImageTk.PhotoImage(Image.open(i))
    canvas=Canvas(win,width=420,height=560)
    canvas.create_image(0,0, image= image, anchor=NW)
    canvas.pack()
    win.mainloop()

YourImageList = ['C:/Users/photo.jpg','C:/Users/photo.jpg']
root = Tk()
for i in YourImageList:
    root.after(0,lambda :ShowAnotherWin(i))
root.title('First')
image= ImageTk.PhotoImage(Image.open(r"C:/Users/photo.jpg"))
canvas=Canvas(root,width=420,height=560)
canvas.create_image(0,0, image= image, anchor=NW)
canvas.pack()
root.mainloop()

YourImageList is the Image list that you want to show.You should put your path in it.
