如何以跨平台方式为python存储桌面应用程序数据？

好吧，我不想成为回答我自己问题的人，但似乎没人知道。我留下后人的答案。

APPNAME = "MyApp"import sysfrom os import path, environif sys.platform == 'darwin':    from AppKit import NSSearchPathForDirectoriesInDomains    # http://developer.apple.com/documentATION/Cocoa/Reference/Foundation/Miscellaneous/Foundation_Functions/Reference/reference.html#//apple_ref/c/func/NSSearchPathForDirectoriesInDomains    # NSApplicationSupportDirectory = 14    # NSUserDomainMask = 1    # True for expanding the tilde into a fully qualified path    appdata = path.join(NSSearchPathForDirectoriesInDomains(14, 1, True)[0], APPNAME)elif sys.platform == 'win32':    appdata = path.join(environ['APPDATA'], APPNAME)else:    appdata = path.expanduser(path.join("~", "." + APPNAME))
