I am getting Content-Length header with get request but I am not getting the same with head request. Why is it so?

I want to check if a webpage's content is changing with python. For let's say in every 1 hour. For that do I need to send get request every 1 hour or is there any other way ?

res.set({'Content-Length': SOMETHING}); What should I put in place of SOMETHING to get the Content-Length ?
