Download files with threads easily

August 13, 2013 Leave a comment

Problem
You have a file with a list of URLs that you want to download. You already know the wget trick:

wget -i down.txt

However, if you want to fetch a lot of files, it can be slow.

Solution
Well, let’s launch wget instances parallelly and fetch those files quickly. With concurrent.futures, it’s just a few lines:

#!/usr/bin/env python

import os
import concurrent.futures
from threading import Lock

lock = Lock()
INPUT = "down.txt"
THREADS = 10

def download(url):
    cmd = "wget -q {url}".format(url=url)
    with lock:
        print cmd
    os.system(cmd)

def main():
    with concurrent.futures.ThreadPoolExecutor(max_workers=THREADS) as ex:
        with open(INPUT) as f:
            for line in f:
                line = line.rstrip("\n")
                ex.submit(download, line)

    main()

Thanks to defnull at reddit who directed me towards conncurrent.futures.

Download PyCon US 2012 videos in a multithreaded way

August 13, 2013 Leave a comment

Note: I wrote this script some time ago when I didn’t know about concurrent.futures. This script does the job nicely but it’s a bit verbose. With concurrent.futures it would be just a few lines.

With the following script you can download all the videos of PyCon US 2012:

#!/usr/bin/env python

"""
Download PyCon US 2012 videos in a multithreaded way.
Requirement: youtube-dl script.

https://pythonadventures.wordpress.com/

PyCon US 2012 videos: http://pyvideo.org/category/17
youtube-dl: http://rg3.github.io/youtube-dl/

Usage:
======
1) download youtube-dl and put it somewhere in the PATH
2) create a subdirectory called "download"
3) launch this script

Total size of the videos is about 27.5 GB.
The download process can take several hours.
You can interrupt the downloading with "killall python".
If you re-launch the script, the downloading will resume.

Tested under Linux with Python 2.7.
