How to detect whether a submission on Reddit is a self post using PRAW?

Question

Is it possible to detect whether a user's submission on reddit is either a self-post or a link to an external URL? I want to exclude all self-posts but can seem to find anything in PRAW's documentation.

Answer 1

All of the attributes listed in the json data of the following URL are available as attributes:

http://www.reddit.com/r/pics/.json?limit=1

The attribute you might be interested in specifically is is_self. In PRAW, you need only test submission.is_self.
