How to do it...

1. Import requests:

>>> import requests

2. Get the list of all posts and display the latest post:

>>> result = requests.get('https://jsonplaceholder.typicode.com/posts')
>>> result
<Response [200]>
>>> result.json()
# List of 100 posts NOT DISPLAYED HERE
>>> result.json()[-1]
{'userId': 10, 'id': 100, 'title': 'at nam consequatur ea labore ea harum', 'body': 'cupiditate quo est a modi nesciunt soluta\nipsa voluptas error itaque dicta in\nautem qui minus magnam et distinctio eum\naccusamus ratione error aut'}

3. Create a new post. See the URL of the new created resource. The call also returns the resource:

>>> new_post = {'userId': 10, 'title': 'a title', 'body': 'something something'}
>>> result = requests.post('https://jsonplaceholder.typicode.com/posts',
              json=new_post)
>>> result
<Response [201]>
>>> result.json()
{'userId': 10, 'title': 'a title', 'body': 'something something', 'id': 101}
>>> result.headers['Location']
'http://jsonplaceholder.typicode.com/posts/101'

Notice that the POST request to create the resource returns 201, which is the proper status for created.

4. Fetch an existing post with GET:

>>> result = requests.get('https://jsonplaceholder.typicode.com/posts/2')
>>> result
<Response [200]>
>>> result.json()
{'userId': 1, 'id': 2, 'title': 'qui est esse', 'body': 'est rerum tempore vitae\nsequi sint nihil reprehenderit dolor beatae ea dolores neque\nfugiat blanditiis voluptate porro vel nihil molestiae ut reiciendis\nqui aperiam non debitis possimus qui neque nisi nulla'}

5. Use PATCH to update its values. Check the returned resource:

>>> update = {'body': 'new body'}
>>> result = requests.patch('https://jsonplaceholder.typicode.com/posts/2', json=update)
>>> result
<Response [200]>
>>> result.json()
{'userId': 1, 'id': 2, 'title': 'qui est esse', 'body': 'new body'}
