Go to this example of Glob Tester Tool to play with this file structure.. Test file patterns. The pathlib module is available in Python 3.4 and above. The output files are all saved in a folder called outfiles that you should have downloaded in the setup for this lesson. — Object-oriented filesystem paths. For example, dir/*. The pattern matches every pathname (file or directory) in the directory dir, without recursing further into subdirectories. To list files in a subdirectory, you must include the subdirectory in the pattern: But in some cases listing and storing them can be a tedious work.
