Question 1.
What is a GET request used for, and which function in the requests library sends one?
Show hintHide hint
Think about which way the data travels: from the server to your program.
Question 2.
What is a GET Request? Explain why it is described as safe and idempotent.
Show hintHide hint
Ask yourself what happens on the server if the same request arrives twice.
3Question 3.
Which argument of requests.get() adds query parameters to the URL?
- params
- data
- json
- headers
Show hintHide hint
The name is short for "parameters".
4Question 4.
Which status code does a successful GET request normally return?
- 200
- 201
- 404
Show hintHide hint
It is the plain "OK" code.
Question 5.
Fetch every post written by user 1 and print the titles, then restructure the code so that it can be tested without a network.
Show hintHide hint
A function that receives `get` as an argument does not care whether it is `requests.get` or a stand-in.
Question 6.
Using only the standard library, write build_get_url(base, params) that returns the URL a GET with params would request. It must escape special characters and, when the base URL already has a query string, add the new pairs with &.
Show hintHide hint
`urlsplit`, `parse_qsl`, `urlencode` and `urlunsplit` from `urllib.parse` do most of the work.
