Python Telegram bot error syntaxError: invalid syntax

Question

I created a simple telegram bot in python that communicates with DialogFlow. This is the code

#!/usr/bin/env python
from telegram.ext import Updater, CommandHandler, MessageHandler, Filters
import apiai, json
updater = Updater (token = '')
dispatcher = updater.dispatcher
# Processing commands
def startCommand (bot, update):
    bot.send_message (chat_id = update.message.chat_id, text = '')
def textMessage (bot, update):
    request = apiai.ApiAI (''). text_request()
request.lang = 'it'
request.session_id = 'TestBot'
request.query = update.message.text
responseJson = json.loads ( request.getresponse (). read (). decode ('utf-8'))
response = responseJson ['result'] ['fulfillment'] ['speech']

if response:
    bot.send_message (chat_id = update.message.chat_id, text = response)
else:
    bot.send_message (chat_id = update.message.chat_id, text = '')

start_command_handler = CommandHandler ('start', startCommand)
text_message_handler = MessageHandler (Filters.text, textMessage)

dispatcher.add_handler (start_command_handler)
dispatcher.add_handler (text_message_handler)

updater.start_polling (clean = True)

updater.idle ()

When I try to start it, i have this error

SyntaxError: invalid syntax

I already installed pip in this way

sudo apt-get install python-pip

Are you using python2.7 ? If yes add the relevant tag

This: *args: Any is Python3-only syntax. You've installed the latest version of tornado which only supports Python 3+. For Python 2.7 you need to downgrade:

pip install -U tornado==5.1.1

5.1.1 is currently the latest version that supports Python 2.7.
