Question

I am building a slackbot, and am trying to receive sms messages from slack. Here is my python code

import os
from flask import Flask, request, Response
from slackclient import SlackClient
from twilio import twiml
from twilio.rest import TwilioRestClient

SLACK_WEBHOOK_SECRET = os.environ.get('SLACK_WEBHOOK_SECRET', None)
WILIO_NUMBER = os.environ.get('TWILIO_NUMBER', None)
USER_NUMBER = os.environ.get('USER_NUMBER', None)

app = Flask(__name__)
slack_client = SlackClient(os.environ.get('SLACK_TOKEN', None))
twilio_client = TwilioRestClient()


@app.route('/twilio', methods=['POST'])
def twilio_post():
    response = twiml.Response()
    if request.form['From'] == USER_NUMBER:
        message = request.form['Body']
        slack_client.api_call("chat.postMessage", channel="#general",
              text=message, username='twiliobot',
              icon_emoji=':robot_face:')
    return Response(response.toxml(), mimetype="text/xml"), 200


@app.route('/slack', methods=['POST'])
def slack_post():
    if request.form['token'] == SLACK_WEBHOOK_SECRET:
        channel = request.form['channel_name']
        username = request.form['user_name']
        text = request.form['text']
        response_message = username   " in "   channel   " says: "   text
        twilio_client.messages.create(to=USER_NUMBER,    from_=TWILIO_NUMBER,
                                  body=response_message)
return Response(), 200


@app.route('/', methods=['GET'])
def test():
   return Response('It works!')


if __name__ == '__main__':
    app.run(debug=True)

When I try running this code with "python twiliobot.py", because it is the name of the app, it returns this error:

File "twiliobot.py", line 33 response_message = username " in " channel " says: " text

What am I doing wrong here? What is wrong with my syntax?

Here's the line in question

response_message = username   " in "   channel   " says: "   text

I assume you're trying to concatenate text. Use the + operator

response_message = username  + " in "  + channel  + " says: "  + text

Or join

response_message = ' '.join([username, "in", channel, "says:",text]

or format

response_message = '{} in {} says: {}'.format(username, channel, text)
