+
+ A string representing the full path::
+
+ >>> PurePosixPath('my/library/setup.py').path
+ 'my/library/setup.py'
+
+ This always returns the same value as ``str(p)``; it is included to
+ serve as a one-off protocol. Code that wants to support both
+ strings and ``pathlib.Path`` objects as filenames can write
+ ``arg = getattr(arg, 'path', arg)`` to get the path as a string.
+ This can then be passed to various system calls or library
+ functions that expect a string. Unlike the alternative
+ ``arg = str(arg)``, this will still raise an exception if an object
+ of some other type is given by accident.
