Google Drive file downloader for Python, with progress bar with tqdm. Based on this SO answer https://stackoverflow.com/a/39225039/3175094

    CHUNK_SIZE = 32*1024
    # TODO: this doesn't seem to work; there's no Content-Length value in header?
    total_size = int(response.headers.get('content-length', 0))

    with tqdm(desc=destination, total=total_size, unit='B', unit_scale=True) as pbar:

I haven't found a reliable way of getting the file size. The response header from the server doesn't have a value for Content-Length, possibly because the data is chunked. If you know the size of the file you want to download, you can manually set the total_size variable to get a proper progress bar.

There should be a way to ask Google's REST API from Python for the size field of the file's metadata. I haven't tried using this, but maybe https://stackoverflow.com/a/44323217/4896937 has some insight?

It seems not work any more. https://drive.google.com/file/d/0B6eKvaijfFUDQUUwd21EckhUbWs/view this file will return port=443 Max retries exceed.

You can get the size of the file from the api by quering from the fileid the filesize.
