You are looking for the request history.
The response.history attribute is a list of responses that led to the final URL, which can be found in response.url.
response = requests.get(someurl)
if response.history:
print("Request was redirected")
for resp in response.history:
print(resp.status_code, resp.url)
print("Final destination:")
print(response.status_code, response.url)
else:
print("Request was not redirected")
Demo:
>>> import requests
>>> response = requests.get('http://httpbin.org/redirect/3')
>>> response.history
(<Response [302]>, <Response [302]>, <Response [302]>)
>>> for resp in response.history:
... print(resp.status_code, resp.url)
...
302 http://httpbin.org/redirect/3
302 http://httpbin.org/redirect/2
302 http://httpbin.org/redirect/1
>>> print(response.status_code, response.url)
