Python requests download file with a tqdm progress bar

dl_requests_tqdm.py

import requests
from tqdm import tqdm


def download(url: str, fname: str, chunk_size=1024):
    resp = requests.get(url, stream=True)
    total = int(resp.headers.get('content-length', 0))
    with open(fname, 'wb') as file, tqdm(
        desc=fname,
        total=total,
        unit='iB',
        unit_scale=True,
        unit_divisor=1024,
    ) as bar:
        for data in resp.iter_content(chunk_size=chunk_size):
            size = file.write(data)
            bar.update(size)

Getting no output from this. Has something changed in tqdm since this was written? It's pretty much exactly what I need, and is downloading fine, but no visual updates. I output the total to the console, so I know it got that far. Updated to the latest tqdm and requests as well.

If there is no content-length in the response, then no output displayed.

Thanks very much. It is a great solution.

Thanks for helping me.

Thanks !

see my fork for additional options:

• try auto detect file name if left empty
• option to overwrite if file already existed
• chunk_size in MiB
