There’s been a bit of discussion on the reliability of getting other users' home directories via os.path.expanduser(), mostly on issue42998 https://bugs.python.org/issue42998. In msg390503 https://bugs.python.org/issue42998#msg390503, Serhiy Storchaka pointed out that ntpath only makes an educated guess of other user’s home directories. In msg390535 https://bugs.python.org/issue42998#msg390535, Eryk Sun supplied an improved ntpath implementation that makes use of winreg and ctypes. In msg391970 https://bugs.python.org/issue42998#msg391970, Steve Dower pointed out that, if retrieving another user’s home directory on Windows is unlikely to be made reliable, we should look at deprecating this functionality in expanduser() From a bit of googling, Python seems to be an outlier in having a function to retrieve another user’s home directory. I am encouraged by Eryk’s patch, but a little out of my depth with Windows stuff. Any views on this? Is expanduser(‘~other’) fixable and worth fixing? If not, should we deprecate this functionality? Or something else? Barney
