Finding levels in the forum

After coming late to the party, I found I missed a few levels. I wrote this to help.

from pyflarum import FlarumUser
from pyflarum.client.extensions import absolutely_all

u = FlarumUser(forum_url="https://box-stacker.artificialworlds.net/", extensions=[absolutely_all.AbsolutelyAllExtension])
done_str='solution by cf'

for discussions in u.absolutely_all_discussions():
    for d in discussions:
        full_discussion = d.get_full_data()
        todo = True
        is_level = False
        for post in full_discussion.get_posts():
            try:
                if post['_parent_included'][0]['attributes']['displayName'] == 'levelsbot':
                    is_level = True
            except KeyError:
                pass 
            try:
                html=post['data']['attributes']['contentHtml']
                if done_str in html:
                    todo = False
            except KeyError:
                pass # not everything has contentHtml
        if is_level:
            print('{: >35}  to do:{}'.format(full_discussion.title, todo))
