How can I get to know what my desktop environment is using Python? I like the result to be gnome or KDE or else.

Tested in Ubuntu 9.10:

在Ubuntu 9.10中测试过:

>>> import os
>>> os.environ.get('DESKTOP_SESSION')
'gnome'

Edit: As mentioned in comments below, this approach will not work for more some OSes. The other two answers provide workarounds.

编辑:正如下面的评论中提到的,这种方法不适用于更多的操作系统。另外两个答案提供了解决方法。

I use this in one of my projects:

我在我的一个项目中使用它:

            if desktop_session is not None: #easier to match if we doesn't have  to deal with caracter cases

                # There is no guarantee that they will not do the same with the other desktop environments.

You might try this:

你可以试试这个:

def detect_desktop_environment():
    desktop_environment = 'generic'
    if os.environ.get('KDE_FULL_SESSION') == 'true':
        desktop_environment = 'kde'
    elif os.environ.get('GNOME_DESKTOP_SESSION_ID'):
        desktop_environment = 'gnome'
    else:
        try:
            info = getoutput('xprop -root _DT_SAVE_MODE')
            if ' = "xfce4"' in info:
                desktop_environment = 'xfce'
        except (OSError, RuntimeError):
            pass
    return desktop_environment

Sometimes people run a mix of desktop environments. Make your app desktop-agnostic using xdg-utils; that means using xdg-open to open a file or url, using xdg-user-dir DOCUMENTS to find the docs folder, xdg-email to send e-mail, and so on.

有时人们会混合使用桌面环境。使用xdg-utils使您的应用程序与桌面无关;这意味着使用xdg-open打开文件或URL,使用xdg-user-dir DOCUMENTS查找docs文件夹,xdg-email发送电子邮件,等等。
