19. # -*- coding: utf-8 -*- import requests def main(word): url = “http://api.duckduckgo.com/?q={}&format=json&pretty=1” url = url.format(word) response = requests.get(url) # io results = response.json()[‘Results’] # io print results
20. def build_url(word): url = “http://api.duckduckgo.com/?q={}&format=json” return url.format(word) def find(url): response = requests.get(url) return response def process_result(response): json = response.json() return json.get(’Results’, []) def main(word): url = build_url(word) response = find(url) print process_result(response)
21. Listen your TESTS
