Use Python Requests to Interact With the iTunes API to Search for Music Info

Tutorial on using Python Requests and using Apple iTunes Music API, where we will be doing the following:

  • Basics of using the Requests module
  • Query iTunes API on Songs by Artist
  • Query iTunes API on Artists Info
  • Query iTunes API on All Albums by Artist
  • Query iTunes API on Top 5 Albums
  • Query iTunes API on Multipe Artists

Resources:

Install the Request Module:

1
2
3
$ virtualenv -p /usr/bin/python .venv
$ source .venv/bin/activate
$ pip install requests

Basic Usage of Requests:

In this demonstration we will only use the GET HTTP Method.

Make the GET Request to the endpoint:

1
2
>>> import requests
>>> response = requests.get('https://itunes.apple.com/search?term=guns+and+roses&limit=1')

View the HTTP Status Code of the Response:

1
2
>>> response.status_code
200

To view some of the status codes of the request library:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
>>> requests.codes.ok
200
>>> requests.codes.no_content
204
>>> requests.codes.temporary_redirect
307
>>> requests.codes.permanent_redirect
308
>>> requests.codes.bad
400
>>> requests.codes.not_found
404
>>> requests.codes.bad_gateway
502

Call .ok for the status lookup, the boolean answer will indicate if it responded with a 200 OK:

1
2
>>> response.ok
True

Measure the amount of time the request took:

1
2
>>> response.elapsed.total_seconds()
0.706043

View the content of the response:

1
2
>>> response.content
