In the Python requests-cache package, how do I detect a cache hit or miss?

The Python https://requests-cache.readthedocs.io/ library can be used to cache requests. If I'm using requests-cache, how do I detect whether a response came from the cache, or had to be re-fetched from the network?

Based on the docs

The following attributes are available on responses:

  • from_cache: indicates if the response came from the cache
  • cache_key: The unique identifier used to match the request to the response (see Request Matching for details)
  • created_at: datetime of when the cached response was created or last updated
  • expires: datetime after which the cached response will expire (see Expiration for details)
  • is_expired: indicates if the cached response is expired (if, for example, an old response was returned due to a request error)

From their example

from requests_cache import CachedSession
session = CachedSession(expire_after=timedelta(days=1))

response = session.get('http://httpbin.org/get')
print(response.from_cache)
