Create a "Saturday Morning Cartoons" Plex playlist

.env

PLEX_URL="http://192.168.1.5:32400"
PLEX_TOKEN=abc123

cartoon_playlist.py

"""
Create a "Saturday Morning Cartoons" playlist from your Plex TV Show collections
named "80s Cartoons" and "90s Cartoons".

Update the values in .env to match your server. Google details on how to find
your X-Plex-Token value and put that in the .env file for PLEX_TOKEN

Then you can run this to create or recreate your playlist:

python cartoon_playlist.py

import os, operator, time, sys, datetime, re
import requests

from dotenv import load_dotenv
from plexapi.server import PlexServer

load_dotenv(verbose=True)

baseurl = os.environ['PLEX_URL']
token = os.environ['PLEX_TOKEN']
plex = PlexServer(baseurl, token)

CARTOON_PLAYLIST_TITLE = 'Saturday Morning Cartoons'

for playlist in plex.playlists():
  if playlist.title == CARTOON_PLAYLIST_TITLE:
    r = requests.delete('{}/playlists/{}?X-Plex-Token={}'.format(baseurl, CARTOON_PLAYLIST_TITLE, token))
    print('{} already exists. Deleting it and will rebuild.'.format(CARTOON_PLAYLIST_TITLE))


tv_shows_section = plex.library.section('TV Shows')
episode_list = []

for collection in tv_shows_section.collection():
  regexp = re.compile(r'(80s|90s) Cartoons')
  if not regexp.search(collection.title):
    break
  print(collection)
  for tv_show in collection.children:
    print(tv_show)
    for episode in tv_show.episodes():
      if not episode.isWatched:
        print(episode.title)
        episode_list += episode
        break

print('Adding {} cartoons to playlist.'.format(len(episode_list)))
plex.createPlaylist(CARTOON_PLAYLIST_TITLE, episode_list)

Got most of the script working, until the end...then I get the following error
Adding 0 cartoons to playlist.

I've not used this script in a few years, but, it seems like it did not find anything to add.

Adding 0 cartoons to playlist.

Verify you have a Collection in your Plex library called "80s Cartoons" or "90s Cartoons". Otherwise the script won't know where to find cartoons to add toy our playlist.

It also seems like the underlying PlexAPI library has changed its syntax. Notice this error:

plexapi.exceptions.BadRequest: Must include items to add when creating new playlist.

Try changing this line:

plex.createPlaylist(CARTOON_PLAYLIST_TITLE, episode_list)

to this:

plex.createPlaylist(CARTOON_PLAYLIST_TITLE, items=episode_list)
