Post to my home Slack channel when a new version of rclone is released. Uses kvdb.io as the key/value store for current version.

# Set environment variables for the following items
slackToken = os.environ['SLACK_TOKEN']
kvdbId = os.environ['KVDB_ID']
rcloneLogo = os.environ['RCLONE_LOGO']

# Pull the rClone page and use BeautifulSoup to parse
page = requests.get('http://rclone.org/downloads')
soup = BeautifulSoup(page.text, 'html.parser')

version_tag = soup.find(id='rclone-download-hahahugoshortcode-0xc4203b8f00-1-hbhb')
versionString = version_tag.text
webVersion = float(versionString.split('v')[1])

session = requests.get('https://kvdb.io/{}/version'.format(kvdbId))
currentVersion = session.json()

if webVersion > currentVersion: 
    slackData = {
        'channel': '#backups',
        'text': 'Woohoo, there is a new rclone version: ' + str(webVersion),
