Simple download function in Python using requests and tqdm

download.py

import pathlib
from urllib.parse import urlparse

import requests
import tqdm


def download(url, root=".", *, name=None, chunk_size=32 * 1024):
    root = pathlib.Path(root)
    root.mkdir(exist_ok=True, parents=True)

    if not name:
        name = pathlib.Path(urlparse(url).path).name

    file = root / name

    with requests.get(url, stream=True) as response, open(file, "wb") as f:
        with tqdm.tqdm(
            total=int(response.headers["Content-Length"]),
            unit="B",
            unit_scale=True,
            unit_divisor=1024,
            dynamic_ncols=True,
        ) as progress_bar:
            for chunk in response.iter_content(chunk_size):
                f.write(chunk)
                progress_bar.update(len(chunk))

    return file
