I'm using python's Turtle Graphics and I want to set a background picture. However, it's not working. I need an answer quick as I have an assignment for my Computer Science class tomorrow >_<. Here's my code:

import time
import sys
import turtle

##Render
turtle.bgpic("background.png")

##End
turtle.done()

And I'm getting this error:

Traceback (most recent call last):
   File "C:/Users/Alfie/Desktop/Youtube Game/Youtube.py", line 6, in <module>
    turtle.bgpic("background.png")
   File "<string>", line 8, in bgpic
   File "C:\Python27\lib\lib-tk\turtle.py", line 1397, in bgpic
    self._bgpics[picname] = self._image(picname)
   File "C:\Python27\lib\lib-tk\turtle.py", line 503, in _image
    return TK.PhotoImage(file=filename)
   File "C:\Python27\lib\lib-tk\Tkinter.py", line 3366, in __init__
    Image.__init__(self, 'photo', name, cnf, master, **kw)
   File "C:\Python27\lib\lib-tk\Tkinter.py", line 3320, in __init__
    self.tk.call(('image', 'create', imgtype, name,) + options)
TclError: couldn't recognize data in image file "background.png"

Followed with a Not Responding screen. Anyone know what the error is?

Tk only supports GIF, PGM and PPM according to this question. Your turtle library uses Tk internally and so you have to use a GIF file for your background.

    In fact the documentation for the turtle package claims it only supports .gif images for the background in [.bgpic](https://docs.python.org/2/library/turtle.html#turtle.bgpic). – Steve Cohen Apr 14 '16 at 17:49

I have tried that function.

  1. I have used format .png --> OK
  2. Remember \\ instead of \ ex: turtle.bgpic("""C:\\Users\\ASUS\\Downloads\\test.gif""") --> So I think at that time, we can use .png in Python turtle.
