下面看看是怎么实现的把

import requests
import sys
with open("%s.mp3" % name, "wb") as code:

if total_length is None:  # no content length header
    code.write(responseMp3.content)
else:
    dl = 0
    total_length = int(total_length)
    for data in responseMp3.iter_content(chunk_size=1024):
        dl += len(data)
        code.write(data)
        done = int(50 * dl / total_length)
        sys.stdout.write("\r[%s%s]" % ('█' * done, ' ' * (50 - done)))
        sys.stdout.flush()

    print('')
    print('下载完成：%s' % name)

很容易对不对_{，感觉还不错}
