HTTP Status Code 403 Forbidden
means:
the server understood the request, but is refusing to fulfill it. Source
The server identified your script as a non-default browser (Chrome, Firefox, etc.) and is refusing to "speak" with it. It's very common to see sites doing this to avoid scrapers, exactly what you're trying to do...
A workaround is to set a user-agent
in your headers, like so:
#!/usr/bin/env python
# -*- coding: utf-8 -*-
import requests
url = "http://www.subscene.com"
headers = {'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/55.0.2883.87 Safari/537.36'}
response = requests.get(url, headers=headers)
print(response) # <Response [200]>
But I advise you to look for a site that provides some sort of API, relying on scraping isn't the best approach.
