I wrote the below code

    command = trigger.group(2)
    if (not command):
        return bot.reply(u'You    did    not    give    me    anything    to    translate')
    def langcode(p):
        return (p.startswith(u':') and (2 < len(p) < 10) and p[1:].isalpha())
    args = [u'auto', u'en']
    for i in range(2):
        if (u'    ' not in command):
            break
        (prefix, cmd) = command.split(u'    ', 1)
        if langcode(prefix):
            args[i] = prefix[1:]
            command = cmd
    phrase = command
    if ((len(phrase) > 350) and (not trigger.admin)):
        return bot.reply(u'Phrase    must    be    under    350    characters.')
    if (phrase.strip() == u''):
        return bot.reply(u'You    need    to    specify    a    string    for    me    to    translate!')
    (src, dest) = args
    if (src != dest):
        (msg, src) = translate(phrase, src, dest, verify_ssl=bot.config.core.verify_ssl)
        if ((sys.version_info.major < 3) and isinstance(msg, str)):
            msg = msg.decode(u'utf-8')
        if msg:
            msg = web.decode(msg)
            msg = (u'"%s"    (%s    to    %s,    translate.google.com)' % (msg, src, dest))
        else:
            msg = (u'The    %s    to    %s    translation    failed,    are    you    sure    you    specified    valid    language    abbreviations?' % (src, dest))
        bot.reply(msg)
    else:
        bot.reply(u'Language    guessing    failed,    so    try    suggesting    one!')
