I'm trying to play around with the API of Reddit, and I understand most of it, but I can't seem to figure out how to access the next page of results (since each page is 25 entries).
Here is the code I'm using:
import requests
import json
r = requests.get(r'https://www.reddit.com/r/Petscop/top.json?sort=top&show=all&t=all')
listing = r.json()
after = listing['data']['after']
data = listing['data']['children']
for entry in data:
post = entry['data']
print post['score']
query = 'https://www.reddit.com/r/Petscop/top.json?after='+after
r = requests.get(query)
listing = r.json()
data = listing['data']['children']
for entry in data:
post = entry['data']
print post['score']
So I extract the after ID as after, and pass it into the next request. However, after the first 25 entries (the first page) the code returns just an empty list ([]). I tried changing the second query as:
r = requests.get(r'https://www.reddit.com/r/Petscop/top.json?after='+after)
And the result is the same. I also tried replacing "after" with "before", but the result was again the same.
Is there a better way to get the next page of results?
Also, what the heck is the r in the get argument? I copied it from an example, but I have no idea what it actually means. I ask because I don't know if it is necessary to access the next page, and if it is necessary, I don't know how to modify the query dynamically by adding after to it.
Try:
query = 'https://www.reddit.com/r/Petscop/top.json?sort=top&show=all&t=all&after='+after
or better:
query = 'https://www.reddit.com/r/Petscop/top.json?sort=top&show=all&t=all&after={}'.format(after)
As for r in strings you can omit it.
