We can get response headers by calling the info() function on the response object. This returns a dictionary, so we can also extract specific header data from the response. Create a url_response_header.py script and write the following content in it:

import urllib.request

x = urllib.request.urlopen('https://www.imdb.com/')
print(x.info())

Run the script as follows:

student@ubuntu:~/work$ python3 url_response_header.py

Here is the output:
