Questions tagged [pathlib]

This tag is for questions about the Python built-in library pathlib, which offers classes representing filesystem paths with semantics appropriate for different operating systems.

This module offers classes representing filesystem paths with semantics appropriate for different operating systems. Path classes are divided between Pure paths, which provide purely computational operations without I/O, and Concrete paths, which inherit from pure paths but also provide I/O operations.

Its strength lies in that it offers a powerful Object Oriented interface for working with paths, as opposed to the string-based interface offered by os.path.

This table offers a mapping between various os functions to their corresponding PurePath/Path equivalent.
