[ Python 常見問題 ] Python Requests library redirect new url

Source From Here 
Question 
I've been looking through the Python Requests documentation but I cannot see any functionality for what I am trying to achieve. In my script I am setting allow_redirects=True. I would like to know if the page has been redirected to something else, what is the new URL. 
For example, if the start URL was: www.google.com/redirect 
And the final URL is www.google.co.uk/redirected 

How do I get that URL? 

How-To 
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:

1. response = requests.get(someurl)  
2. if response.history:  
3.     print "Request was redirected"  
4.     for resp in response.history:  
5.         print resp.status_code, resp.url  
6.     print "Final destination:"  
7.     print response.status_code, response.url  
8. else:  
9.     print "Request was not redirected"  

A real demo as below: 

>>> import requests 
>>> response = requests.get('http://httpbin.org/redirect/3') 
>>> for resp in response.history: 
... print("{}\t{}".format(resp.status_code, resp.url)) 
... 
302 http://httpbin.org/redirect/3 
302 http://httpbin.org/relative-redirect/2 
302 http://httpbin.org/relative-redirect/1 
>>> print("Final URL={} with status code = {}".format(response.url, response.status_code)) 
Final URL=http://httpbin.org/get with status code = 200
