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. If you've never used this module before or just aren't sure which class is right for your task, Path is most likely what you need The os.path module is always the path module suitable for the operating system Python is running on, and therefore usable for local paths. However, you can also import and use the individual modules if you want to manipulate a path that is always in one of the different formats. They all have the same interface: posixpath for UNIX-style paths All Python releases are Open Source. Historically, most, but not all, Python releases have also been GPL-compatible.
