How can I find all public repos in github that a user contributes to?

I'm using the github3 python library and am trying to find all public
repos that users from our organization have contributed to (to reward the
support of open source!). I've got the list of users for the organization,
but now what? Can I use the public events iterator to find repos?
!/usr/bin/env python
import argparse import github3
def get_organization(github, name): for organization in
github.iter_orgs(): if organization.login == name: return organization
def main(args): github = github3.login(args.github_username,
password=args.github_password) organization = get_organization(github,
args.organization)
# Get a list of all current organization contributors
orgMembers = [member.login for member in organization.iter_members()]
now what?
