Simple download function with progress bar

download.py

# Requires clint (https://github.com/kennethreitz/clint) from the develop branch, because of the expected_size argument.

def download(url, to_file, chunk_size=8192):
    r = requests.get(url)
    size = int(r.headers['Content-Length'])
    expected_size = size / chunk_size

    with open(to_file, 'w') as f:
        for chunk in progress.bar(r.iter_content(chunk_size=chunk_size), expected_size=expected_size):
            f.write(chunk)

awesome :)

Thanks! It's my new wget! =P
