playlist content scrapping

[mzramna]

i was trying to extract the ids from a playlist into youtube,but it has to download all data from all playlist before i was able to get any data from anything in there ,since it has already downloaded this data that i need to begin the process of downloading all the other datas , it has a way to get this and i just couldnt find it or it is unable to do it just using the youtube-dl library for python?Since i'm working with a enormous playlist(this one into the code is an exemple much smaller than the one that i'm using) i cant wait it to download all the unecessary data from all the playlist every time i run the script,ps json is to store all the processed and unprocessed data

from youtube_dl import YoutubeDL
import json
url = 'PLMC9KNkIncKvYin_USF1qoJQnIyMAfRxl'
ytdl = YoutubeDL()
info = ytdl.extract_info(url, download=False)['id']
print(info.keys())
print (info['id'])
with open('youtube_dl_datamining.txt','w') as output_file:
json.dump(info,output_file)
