Consider the following Path:
import pathlib
path = pathlib.Path(r'C:\users\user1\documents\importantdocuments')
How can I extract the exact string documents\importantdocuments from that Path?
I know this example looks silly, the real context here is translating a local file to a remote download link.
Use the PurePath.relative_to() method to produce a relative path.
You weren't very clear as to how the base path is determined; here are two options:
secondparent = path.parent.parent
homedir = pathlib.Path(r'C:\users\user1')
then just use str() on the path.relative_to(secondparent) or path.relative_to(homedir) result.
Demo:
>>> import pathlib
>>> path = pathlib.Path(r'C:\users\user1\documents\importantdocuments')
>>> secondparent = path.parent.parent
>>> homedir = pathlib.Path(r'C:\users\user1')
>>> str(path.relative_to(secondparent))
'documents\\importantdocuments'
>>> str(path.relative_to(homedir))
'documents\\importantdocuments'
This works on any OS and every version of Python:
import os
os.path.join(os.path.basename(os.path.dirname(p)),os.path.basename(p))
This works on python 3:
str(p.relative_to(p.parent.parent))
