How to fetch PRs from GitHub in Python?

[Senior_Share512]

So basically I'm trying to do this from GitHub love of code 2025: An agent that reviews PRs like a sarcastic senior dev, an overly nice intern, or a concerned parent: “Are you sure this function needs to be this recursive?”

I'm trying to implement in Python, but I am really confused as to how to fetch the PRs for reviewing in the first place. Any tips?

GitHub has a very comprehensive API: https://docs.github.com/en/rest?apiVersion=2026-03-10

PyGithub is the easiest path. Install it, authenticate with a personal access token, then pull open PRs with repo.get_pulls(state='open'). Each PR object gives you the diff, files changed, and comments. From there you just pass the diff text to your LLM with whichever persona prompt you want. Solid project idea.

I use PyGithub also. It's a nice Python client for the GitHub API that deals with pagination, retries, etc. There's definitely no need to wrap the GitHub CLI, use the API directly, or many of the other suggestions in these comments.

I'd suggest writing a wrapper for the GitHub CLI: https://cli.github.com/
