    abspath = os.path.abspath(os.path.join(path, filename))
    if os.path.isfile(abspath):

    if media_id:
        s.send_to_story(media_id, time=5)

def main():
    username = # Your username goes here
    password = # Your password goes here
    path = 'Documents/snaps' #where you download the snaps to

    s = Snapchat()
    if not s.login(username, password).get('logged'):
        print('Invalid username or password')
        sys.exit(1)

    new_snaps = []
    for snap in s.get_snaps():
        result = process_snap(s, snap, path)
        if result:
            new_snaps.append(result)
    for snap_path in new_snaps:
        upload_story(s, snap_path)


if __name__ == '__main__':
    main()

Great hack. Would love to see some form of permissions that only allows snaps from certain Snapchat users to be published on the account, rather than everyone with this account added being able to publish.

Can someone confirm what this hack does?
