Is There Any Way To Check if a Twitch Stream Is Live Using Python?

Question

I\'m just wondering if there is any way to write a python script to check to see if a twitch.tv stream is live?

I\'m not sure why my app engine tag was removed, but this

RocketDonkey's fine answer seems to be outdated by now, so I'm posting an updated answer for people like me who stumble across this SO-question with google. You can check the status of the user EXAMPLEUSER by parsing

https://api.twitch.tv/kraken/streams/EXAMPLEUSER

The entry "stream":null will tell you that the user if offline, if that user exists. Here is a small Python script which you can use on the commandline that will print 0 for user online, 1 for user offline and 2 for user not found.

#!/usr/bin/env python3

# checks whether a twitch.tv userstream is live

import argparse
from urllib.request import urlopen
from urllib.error import URLError
import json

def parse_args():
    """ parses commandline, returns args namespace object """
    desc = ('Check online status of twitch.tv user.\n'
            'Exit prints are 0: online, 1: offline, 2: not found, 3: error.')
    parser = argparse.ArgumentParser(description = desc,
             formatter_class = argparse.RawTextHelpFormatter)
    parser.add_argument('USER', nargs = 1, help = 'twitch.tv username')
    args = parser.parse_args()
    return args

def check_user(user):
    """ returns 0: online, 1: offline, 2: not found, 3: error """
    url = 'https://api.twitch.tv/kraken/streams/' + user
    try:
        info = json.loads(urlopen(url, timeout = 15).read().decode('utf-8'))
        if info['stream'] == None:
            status = 1
        else:
            status = 0
    except URLError as e:
        if e.reason == 'Not Found' or e.reason == 'Unprocessable Entity':
            status = 2
        else:
            status = 3
    return status

# main
try:
    user = parse_args().USER[0]
    print(check_user(user))
except KeyboardInterrupt:
    pass
