# Program to get a list of video titles from a Youtube Channel
import youtube_dl
import pickle

'''
Visit the Channel page and view page source
Search for externalID and copy the value into PLAYLIST_ID below
Change the C to a U so it begins UU instead of UC (U=Upload Playlist)
'''

PLAYLIST_ID = ''

with youtube_dl.YoutubeDL({'ignoreerrors': True}) as ydl:
     playd = ydl.extract_info(PLAYLIST_ID, download=False)

     with open('playlist.pickle', 'wb') as f:
         pickle.dump(playd, f, pickle.HIGHEST_PROTOCOL)
     
     with open('playlist.pickle', 'rb') as f:
         data = pickle.load(f)
     
     for video in data['entries']:
         for property in ['title']:
             print(video.get(property))

how will it work?
