Response Status Codes

We can check the response status code:

>>> r = requests.get('http://httpbin.org/get')
>>> r.status_code
200

Requests also comes with a built-in status code lookup object for easy reference:

>>> r.status_code == requests.codes.ok
True

If we made a bad request (a 4XX client error or 5XX server error response), we can raise it with Response.raise_for_status():

>>> bad_r = requests.get('http://httpbin.org/status/404')
>>> bad_r.status_code
404
>>> bad_r.raise_for_status()
Traceback (most recent call last):
  File "requests/models.py", line 832, in raise_for_status
    raise http_error
requests.exceptions.HTTPError: 404 Client Error

But, since our status_code for r was 200, when we call raise_for_status() we get:

>>> r.raise_for_status()
None

All is well.
