That's what I thought as well. Then I found https://bugs.python.org/issue19776 and it looks like this is a well known issue. Hopefully the patches are working and will be accepted in the next release or so.
Given how often os.path.expanduser() is needed, I'm a little surprised that the pathlib module was even put in provisionally. I do like how it works, however. Paths as objects and not strings! Its a beautiful idea, just not 100% complete. PS: For those who are curious, the 2 issues that seemed to hold things up the most are non-Unix systems (Windows) and how to handle when there is no home directory. Posix only says that the results are undefined. > On Dec 24, 2014, at 8:38 AM, Skip Montanaro <skip.montan...@gmail.com> wrote: > >>>> p.resolve() > ... > FileNotFoundError: [Errno 2] No such file or directory: '/Users/chris/~' > > I've not used the pathlib module yet, but poked through the > documentation.
