When you try to scrape reddit make sure to send the 'headers' on your request.
6+
Reddit blocks scrappers so we have to include these headers to make reddit think
7+
that we are a normal computer and not a python script.
8+
How to use: requests.get(url, headers=headers)

All subreddits have the same url:

i.e : https://reddit.com/r/javascript

To make a request, use this url:
19+
https://www.reddit.com/r/{subreddit}/top/?t=month

This will give you the top posts in per month.
