New submission from Mark Hammond <hamm...@finleme.com>:
Comparing two paths, PurePath.relative_to fails with ValueError if the second path is not in the first. >>> Path('/a/b').relative_to('/a/b/c') Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/lib/python3.9/pathlib.py", line 928, in relative_to raise ValueError("{!r} is not in the subpath of {!r}" ValueError: '/a/b' is not in the subpath of '/a/b/c' OR one path is relative and the other is absolute. Please extend PurePath.relative_to so it is able to output a relative path in form of '..' instead of an error. Currently, the only way to do this is to use relpath from os.path but it would be very useful if Path was able to output the relative path. ---------- components: Library (Lib) messages: 393262 nosy: mhammondr priority: normal severity: normal status: open title: Output relative path when using PurePath.relative_to type: enhancement versions: Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue44078> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
