Checking HTTP headers

The response.headers statement provides the headers of the web server response. Basically, the response is an object dictionary, and with the items() method, we can iterate with the key-value format for access to the header's response.

#!/usr/bin/env python3import requestsresponse = requests.get('http://github.com')try:    for key,value in response.headers.items():        print('%s: %s' % (key, value))except Exception as error:    print('%s' % (error))
