How to use JSON in Python?

Question

I am using the following code to collect the API from the Urbandictionary site

import requests
import json

page = requests.get("http://api.urbandictionary.com/v0/define?term=hello")
print(page.content)

Right after execution, I get the following result:

b'{"tags":["hi","hi","hey","hey","greeting","greeting","yo","yo","goodbye","goodbye"],"result_type":"exact","list":[{"definition":"what you say when your talking casually with friends and your mom walks in the room","permalink":"http://hello.urbanup.com/69266","thumbs_up":3545,"author":"mad at the world","word":"hello","defid":69266,"current_vote":"","example":"What the hell(mom enters)-o mom.","thumbs_down":979},{"definition":"The only word on this site that has nothing to do with [sex] or [drugs]!","permalink":"http://hello.urbanup.com/2269237","thumbs_up":2132,"author":"pirates rule!!!","word":"Hello","defid":2269237,"current_vote":"","example":"person 1: hello\\r\\nPerson 2: hi\\r\\nPerson 1: goodbye\\r\\nPerson 2: Farewell, and may the forces of evil become confused in their eternal search for you\\r\\n*person 1 runs away*","thumbs_down":480},{"definition":"1.

How can I receive the value included in "Definition"?

Answer 1

If the content you picked up was in JSON you can use the method .json() of own requests that will return a Dict.

Would look like this:

page = requests.get("http://api.urbandictionary.com/v0/define?term=hello")
print(page.json())
{'sounds': ['http://media.urbandictionary.com/sound/hello-7503.mp3', 'http://media.urbandictionary.com/sound/hello-9778.mp3', 'http://media.urbandictionary.com/sound/hello-9897.mp3', 'http://media.urbandictionary.com/sound/hello-10454.mp3', 'http://api.twilio.com/2008-08-01/Accounts/ACd09691b82112e4b26fce156d7c01d0ed/Recordings/RE35ab2d198fde01bc8889d6bedc7d3108.mp3', 'http://api.twilio.com/2008-08-01/Accounts/ACd09691b82112e4b26fce156d7c01d0ed/Recordings/RE7201bb8cc62883692ba7afc67037d5ff.mp3', 'http://wav.urbandictionary.com/hello-25244.wav', 'http://wav.urbandictionary.com/hello-37770.wav', 'https://api.twilio.com/2008-08-01/Accounts/ACd09691b82112e4b26fce156d7c01d0ed/Recordings/REa6a85510c89613bfc29fd715761f144c.mp3', 'http://wav.urbandictionary.com/hello-46397.wav'], 'result_type': 'exact', 'list': [{'defid': 69266, 'author': 'mad at the world', 'word': 'hello', 'thumbs_down': 979, 'thumbs_up': 3548, 'permalink': 'http://hello.urbanup.com/69266', 'example': 'What the hell(mom enters)-o mom.', 'definition': 'what you say when your talking casually with friends and your mom walks in the room', 'current_vote': ''}, {'defid': 2269237, 'author': 'pirates rule!!!', 'word': 'Hello', 'thumbs_down': 480, 'thumbs_up': 2133, 'permalink': 'http://hello.urbanup.com/2269237', 'example': 'person 1: hello\r\nPerson 2: hi\r\nPerson 1: goodbye\r\nPerson 2: Farewell, and may the forces of evil become confused in their eternal search for you\r\n*person 1 runs away*', 'definition': 'The only word on this site that has nothing to do with [sex] or [drugs]!', 'current_vote': ''}, {'defid': 390319, 'author': 'DJ', 'word': 'hello', 'thumbs_down': 350, 'thumbs_up': 723, 'permalink': 'http://hello.urbanup.com/390319', 'example': "1.

Edit: As the function .json() returns a Dict you need to access with the keys in your case you want to Definition.

page = requests.get("http://api.urbandictionary.com/v0/define?term=hello")
d = page.json()
for i in d['list']:
   print(i['definition'])

For there are several Definition and can be accessed through the key list

I recommend that whenever you have any questions about json format use some formatting tool, for example: https://jsonformatter.curiousconcept.com/ Take the value of http://api.urbandictionary.com/v0/define?term=hello there.
