tkinter.TclError: image “pyimage3” doesn't exist

Question

I\'m having trouble with a function that shows an image for two seconds on screen, and then is destroyed. When the program runs the functions initial call procedurely works

Answer 1

Maybe not for this exact case, but for a similar one, I found that the customary

if __name__ == '__main__':
    wlcm_scrn()  #Call through procedure.

solves the problem as well. This seems to kill the active window and to create a new one each time you re-call the same module.
