Correct Answer:
Explanation:
The correct URL from next page can be retrieved by using response.links[ ' next ' ][ ' url ' ]. The use of response.headers.get( ' Link ' ) could be easily replaced by an infinite loop like ' while True: ' and it would be the same. They ' re just testing our knowledge here. The trick here is that once we reach the last page, response.links[ ' next ' ][ ' url ' ] within the ' try ' context will fail and we ' ll move to the ' except ' clause and the program will exit.
