1. After a delay of 3s (3000ms), the card should flip and display the English translation for the current word.

2. The card image should change to the card_back.png and the text colour should change to white. The title of the card should change to "English" from "French".

e.g.

HINTS:

1. To change the canvas image, you'll need a reference to the image, like what you have with the text created in the canvas. Then you can set the image attribute using itemconfig(). e.g.

new_image = PhotoImage(file="new_image.png")
old_image = PhotoImage(file="old_image.png")
canvas_image = canvas.create_image(300, 300, image=old_image)
#To change the image:
canvas.itemconfig(canvas_image, image=new_image)

IMPORTANT: PhotoImage objects should not be created inside a function. Otherwise, it will not work.

2. To change the color of the text in a canvas element, use the fill parameter. e.g. https://stackoverflow.com/questions/41030973/how-can-i-change-the-color-of-text-in-tkinter

3. Remember in the mainloop() you should not create additional delayed loops e.g. with time.sleep() but instead, use window.after() e.g. Tkinter Reference Manual: .after() method

4. You can cancel a window.after() loop using window.after_cancel() e.g. Tkinter Reference Manual: .after_cancel() method
