How to list all files with a certain extension recursively?

I want to retrieve a list of files (filtered by extension) inside a directory (recursively).

I have the solution below but I am confident there is a cleaner way to do that. Probably a simple glob expression that I am missing but any better solution is fine. Better in this scenario is readability (self-documenting) not performance.

I know this example is very simple, but of course it is part of a more complex scenario.

files = glob.glob('documents/*.txt') + glob.glob('documents/**/*.txt')

I'd expect something like

files = glob.glob('playbooks/(**/)?*.yml')

(just an example, that does not work)

To make use of the ** specifier in glob.glob() you need to explicitly set recursive parameter to True, e.g.:

glob.glob('Documents/**/*.txt', recursive=True)

From the official doc:

If recursive is true, the pattern “**” will match any files and zero or more directories, subdirectories and symbolic links to directories. If the pattern is followed by an os.sep or os.altsep then files will not match.
