Python progress bar and downloads

Question

I have a python script that launches a URL that is a downloadable file. Is there some way to have python use commandline to display the download progress as oppose to launch

Answer 1

You can use the 'clint' package (written by the same author as 'requests') to add a simple progress bar to your downloads like this:

from clint.textui import progress

r = requests.get(url, stream=True)
path = '/some/path/for/file.txt'
with open(path, 'wb') as f:
    total_length = int(r.headers.get('content-length'))
    for chunk in progress.bar(r.iter_content(chunk_size=1024), expected_size=(total_length/1024) + 1): 
        if chunk:
            f.write(chunk)
            f.flush()

which will give you a dynamic output which will look like this:

[################################] 5210/5210 - 00:00:01

It should work on multiple platforms as well! You can also change the bar to dots or a spinner with .dots and .mill instead of .bar.

Enjoy!
