pathlib: 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.
