cross-platform splitting of path in python

by

Python 3.4 introduced a new module pathlib. pathlib.Path provides file system related methods, while pathlib.PurePath operates completely independent of the file system:

>>> from pathlib import PurePath
>>> path = "/foo/bar/baz/file"
>>> path_split = PurePath(path).parts
>>> path_split
('\\', 'foo', 'bar', 'baz', 'file')

You can use PosixPath and WindowsPath explicitly when desired:

>>> from pathlib import PureWindowsPath, PurePosixPath
>>> PureWindowsPath(path).parts
('\\', 'foo', 'bar', 'baz', 'file')
>>> PurePosixPath(path).parts
("https://stackoverflow.com/", 'foo', 'bar', 'baz', 'file')

And of course, it works with Windows paths as well:

>>> wpath = r"C:\foo\bar\baz\file"
>>> PurePath(wpath).parts
('C:\\', 'foo', 'bar', 'baz', 'file')
>>> PureWindowsPath(wpath).parts
('C:\\', 'foo', 'bar', 'baz', 'file')
>>> PurePosixPath(wpath).parts
('C:\\foo\\bar\\baz\\file',)
>>>
>>> wpath = r"C:\foo/bar/baz/file"
>>> PurePath(wpath).parts
('C:\\', 'foo', 'bar', 'baz', 'file')
>>> PureWindowsPath(wpath).parts
('C:\\', 'foo', 'bar', 'baz', 'file')
>>> PurePosixPath(wpath).parts
('C:\\foo', 'bar', 'baz', 'file')

Huzzah for Python devs constantly improving the language!
