You can use the _winreg module on windows: First find out the path in the registry (eg starting regedit.exe and using its find function). 您可以在Windows上使用_winreg模块：首先找出注册表中的路径（例如，启动regedit.exe并使用其find函数）。 Then you can query this path as I did it once to find the home directory of R: 然后你可以查询这条路径，就像我做了一次找到R的主目录：
key = _winreg.OpenKey(_winreg.HKEY_LOCAL_MACHINE, "Software\\R-core\\R")
value = _winreg.QueryValueEx(key, "InstallPath")[0]
ADDED : 增加 ：
If you are not familiar with the windows regstry: have a look at http://en.wikipedia.org/wiki/Windows_Registry 如果您不熟悉windows regstry：请查看http://en.wikipedia.org/wiki/Windows_Registry
