... pathlib.


The goal of this series of videos is to demonstrate how to deal with files, paths and folders from python programmatically. We'll mainly discuss the python pathlib module.


Episode Notes

You can iterate over files and folders that match a pattern by using the .glob() method on a path. An example is listed below;

[p for p in Path().glob("data/*/*.json")]

Note the power of having the list comprehension. Every p in the loop below is a Path-object. This means that we can apply all methods on it that we mentioned before. Here's an example;

[p.parent for p in Path().glob("data/*/*.json")]

But you can do anything you'd like here. For example, maybe we also would like to allow for .csv files.

[p for p in Path().glob("data/*/*") if p.suffix in ('.csv', '.json')]

Comprehensions are powerful, also with Path.glob(). There's even a more powerful setting that you can do by using ** instead of *. Try it;

[p for p in Path().glob("**/*.json")]

The results will now be found recursively in all folders.
