In Python Tkinter, how do I get the index of an image embedded in a text widget using the name?

Question

I am creating an app using Python Tkinter in which I give the users an option to insert an image into a text widget. I know that when you insert an image, and you don't specify the name attribute, tkinter automatically generates one. There is also a way to get a tuple of all the names in the text widget using the text.image_names() method. All the methods I have looked at, that relate to text widget images only take the image's index as an attribute. However, I don't know the image's index.

It would be nice if anyone could tell me if there is a method where I give the function the image's name is an attribute, and get the index in return.

You can use Text.index() on the image name to get the image index in "line.column" format.

Below is an example:

import tkinter as tk

root = tk.Tk()

text = tk.Text(root, width=80, height=20)
text.pack()

text.insert('end', 'This is line 1\n')
text.insert('end', 'Embed an image ')
img = tk.PhotoImage(file='sample.png')
text.image_create('end', image=img, name='img1')
text.insert('end', ' in a line')

print('Image with name "img1" is at index', text.index('img1'))

root.mainloop()

You will get Image with name "img1" is at index 2.15 in the console.
