I need some help with the Alexa Development Console. I want to implement a new Alexa Skill with an external API where you can trade or sell stocks with Alexa. I used to Python for coding and requests & json library.

Whenever I try to test my code, Alexa says something like "What do you mean" or reads out a Wikipedia article (Still haven't used AWS, but how can I link the API with AWS?). Can someone tell me what is wrong with my code here:

# -*- coding: utf-8 -*-

# This sample demonstrates handling intents from an Alexa skill using the Alexa Skills Kit SDK for Python.
# Please visit https://alexa.design/cookbook for additional examples on implementing slots, dialog management,
# session persistence, api calls, and more.
# This sample is built using the handler classes approach in skill builder.
