Generally speaking you can introspect Python objects with the dir() and vars() functions:

>>> import requests
>>> response = requests.get('http://httpbin.org/get?foo=bar')
>>> dir(response)
['__attrs__', '__bool__', '__class__', '__delattr__', '__dict__', '__doc__', '__format__', '__getattribute__', '__getstate__', '__hash__', '__init__', '__iter__', '__module__', '__new__', '__nonzero__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__setstate__', '__sizeof__', '__str__', '__subclasshook__', '__weakref__', '_content', '_content_consumed', 'apparent_encoding', 'close', 'connection', 'content', 'cookies', 'elapsed', 'encoding', 'headers', 'history', 'is_permanent_redirect', 'is_redirect', 'iter_content', 'iter_lines', 'json', 'links', 'ok', 'raise_for_status', 'raw', 'reason', 'request', 'status_code', 'text', 'url']
>>> 'url' in dir(response)
True
>>> vars(response).keys()
['cookies', '_content', 'headers', 'url', 'status_code', '_content_consumed', 'encoding', 'request', 'connection', 'elapsed', 'raw', 'reason', 'history']

You could also just use the help() function and Python will format the docstrings on a class; response.url doesn't have a docstring but is listed in the attributes section.

For requests specifically, just check out the excellent API documentation. The url attribute is listed as part of the Response object.

If the response is in json you could do something like (python3):

Copyimport json
import requests as reqs

# Make the HTTP request.
response = reqs.get('https://demo.ckan.org/api/3/action/group_list')

# Use the json module to load CKAN's response into a dictionary.
response_dict = json.loads(response.text)

for i in response_dict:
    print("key: ", i, "val: ", response_dict[i])

To see everything in the response you can use .__dict__:

Copyprint(response.__dict__)

Edit in May 2024 to add a suggestion on how to address if objects in the response dict is not JSON serializable.

Copyimport json
...
print(json.dumps(response.text, indent=4, sort_keys=True, default=lambda o:'<not serializable>'))
