![]() On Windows, you will see something like this: Independently of the operating system you are using, paths are represented in Posix style, with the forward slash as the path separator. However, let me leave you with a few other tidbits. The Object-oriented approach is already quite visible in the examples above (especially if you contrast it with the old os.path way of doing things). In fact, the official documentation of pathlib is titled pathlib - Object-oriented filesystem paths. In the introduction, we briefly noted that paths are not strings, and one motivation behind pathlib is to represent the file system with proper objects. ![]() Instantiating PurePath will return one of these objects depending on the operating system you are using. You can directly instantiate PureWindowsPath or PurePosixPath on all systems. exists () AttributeError: 'PureWindowsPath' object has no attribute 'exists' parent PureWindowsPath('C:/Users/gahjelle/realpython') > path. PureWindowsPath ( r 'C:\Users\gahjelle\realpython\file.txt' ) > path. Time for action: let us see how pathlib works in practice. If you are stuck on legacy Python, there is also a backport available for Python 2. It gathers the necessary functionality in one place and makes it available through methods and properties on an easy-to-use Path object.Įarly on, other packages still used strings for file paths, but as of Python 3.6, the pathlib module is supported throughout the standard library, partly due to the addition of a file system path protocol. ![]() The pathlib module was introduced in Python 3.4 ( PEP 428) to deal with these challenges. ![]() This difference can lead to hard-to-spot errors, such as our first example in the introduction working for only Windows paths. Recall that Windows uses \ while Mac and Linux use / as a separator. For instance, instead of joining two paths with like regular strings, you should use os.path.join(), which joins paths using the correct path separator on the operating system. With paths represented by strings, it is possible, but usually a bad idea, to use regular string methods. Import glob import os import shutil for file_name in glob. ![]()
