我如何去除python乌龟中的bgimage

我类似地导入了BG图像

screen = turtle.Screen()


#reference image
screen.bgpic("image.png")

，然后我制作了图形，但是我想删除BG图像，因此只保留BGColor，如果i screen.clear.clear（），它可以清除我用Turtle绘制的一切。

原文

I imported an bg image like so

screen = turtle.Screen()


#reference image
screen.bgpic("image.png")

then I made my graphic but I want to remove the bg image so only the bgcolor remains and if I screen.clear() it clears everything I drew with turtle.

根据文档，将'nopic'作为picname参数，它将删除当前图像：

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

'nopic' token在询问bgpic（）如果没有背景图像集：

% python3
Python 3.8.3 (v3.8.3:6f8c8320e9, May 13 2020, 16:29:34) 
[Clang 6.0 (clang-600.0.57)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import turtle
>>> turtle.bgpic()
'nopic'
>>>

Per the documentation, pass 'nopic' as the picname argument and it will remove the current image:

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

The 'nopic' token is also returned when interrogating bgpic() if there is no background image set:

% python3
Python 3.8.3 (v3.8.3:6f8c8320e9, May 13 2020, 16:29:34) 
[Clang 6.0 (clang-600.0.57)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import turtle
>>> turtle.bgpic()
'nopic'
>>>
