Aggregation 2 — Python: Trees

Let's practice with another option for data aggregation on file systems. We'll write a function that accepts a directory as input and returns a list of directories of the first level of nesting and the number of files inside each of them, including all subdirectories:

from hexlet import fs

tree = fs.mkdir('/', [
    fs.mkdir('etc', [
        fs.mkdir('apache'),
        fs.mkdir('nginx', [
            fs.mkfile('nginx.conf'),
        ]),
    ]),
    fs.mkdir('consul', [
        fs.mkfile('config.json'),
        fs.mkfile('file.tmp'),
        fs.mkdir('data'),
    ]),
    fs.mkfile('hosts'),
    fs.mkfile('resolve'),
