How to set background in turtle python

Question

i am working on a space invaders game, and i have a problem, my background is not working. Here is he code that was necessary, but didn't work:

wn = turtle.Screen() 
wn.bgcolor("black")
wn.title("Space Invaders")
wn.bgpic('space_invaders_background.gif')

and the error message said

'[Running] python -u "d:\USERS\chedl\Documents\Apps\games_and_apps\offline\python\space_invaders\main.py" Traceback (most recent call last): File "d:\USERS\chedl\Documents\Apps\games_and_apps\offline\python\space_invaders\main.py", line 10, in wn.bgpic('space_invaders_background.gif') File "C:\Users\chedl\AppData\Local\Programs\Python\Python36\lib\turtle.py", line 1481, in bgpic self._bgpics[picname] = self._image(picname) File "C:\Users\chedl\AppData\Local\Programs\Python\Python36\lib\turtle.py", line 479, in _image return TK.PhotoImage(file=filename) File "C:\Users\chedl\AppData\Local\Programs\Python\Python36\lib\tkinter__init__.py", line 3539, in init Image.init(self, 'photo', name, cnf, master, **kw) File "C:\Users\chedl\AppData\Local\Programs\Python\Python36\lib\tkinter__init__.py", line 3495, in init self.tk.call(('image', 'create', imgtype, name,) + options) _tkinter.TclError: couldn't open "space_invaders_background.gif": no such file or directory

[Done] exited with code=1 in 0.273 seconds'

but the space_invaders_background.gif is in the same file as the actual python application.

also, if you want the path, here it is D:\USERS\chedl\Documents\Apps\games_and_apps\offline\python\space_invaders\space_invaders_background.gif — nate ethan
I don't need this path. You should try using it in your code. I can't hack into your directory ;) — Sheldore

I will list the documentation needed to change the colors. Furthermore, I do not see how you have a file that is both a gif and a python script. Are you saying the main.py and my.gif are in the same directory? If so, list the directory name as a full path. What is your OS? Windows? Then full path is C:\my\path\to\script\my.gif. If Unix, /this/is/a/path/and/dir/my.gif.

Per docs:

turtle.bgcolor(*args)
    Parameters: args – a color string or three numbers in the range 0..colormode or 
    a 3-tuple of such numbers
    Set or return background color of the TurtleScreen.

>>> screen.bgcolor("orange")
>>> screen.bgcolor()
'orange'
>>> screen.bgcolor("#800080")
>>> screen.bgcolor()
(128, 0, 128)

turtle.bgpic(picname=None)
    Parameters: picname – a string, name of a gif-file or "nopic", or None
    Set background image or return name of current backgroundimage. 
    If picname is a filename, set the corresponding image as background. 
    If picname is "nopic", delete background image, if present. 
    If picname is None, return the filename of the current backgroundimage.

>>> screen.bgpic()
'nopic'
>>> screen.bgpic("landscape.gif")
>>> screen.bgpic()
"landscape.gif"
