4 Python code def bgpic (self, picname=None): "Set backgroundimage 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. Example (for a TurtleScreen instance named screen): > screen.bgpic () 'nopic' > screen.bgpic ("landscape.gif") > screen.bgpic ()' landscape.gif' "if picname is None: return self._bgpicname if picname not in self._bgpics: self._ bgpics [picname] = self._image (picname) self._setbgpic (self._bgpic) Self._ bgpics [coding]) self._bgpicname = picname # coding: utf-8import pygameimport osimport sysfrom pygame.locals import * os.chdir ('confession under the stars') os.getcwd () pygame.init () pygame.mixer.init () pygame.mixer.music.load ("beauty of the stars.
