Pafy – Getting Meta Data for Each Item of Playlist

In this article we will see how we can get the meta data of each item of playlist in pafy. Pafy is a python library to download YouTube content and retrieve metadata. Pafy object is the object which contains all the information about the given video. A playlist in YouTube is a list, or group, of videos that plays in order, one video after the other. Metadata is “data that provides information about other data”. In other words, it is “data about data.” Many distinct types of metadata exist, including descriptive metadata, structural metadata, administrative metadata, reference metadata and statistical metadata. We can get the playlist from youtube in pafy with the help of get_playlist method, below is the command given to do this

 pafy.get_playlist(url)

The playlist url should exist on youtube as it get the information of those videos which are present on the youtube. YouTube is an American online video-sharing platform.

Steps to get the playlist ID 1. Import the pafy module 2. Get the playlist with the help of URL of playlist 3. Return play list work as dictionary so use ‘items’ as key with the return playlist 4. Store the result in variable and from the items select the single item 5. With the single item use ‘playlist_meta’ key with it 6. Store the result in a variable and save it.

Below is the implementation 

Output :

{'added': '06/01/2016', 'is_cc': False, 'is_hd': True, 'likes': 1111, 'title': 'Write a program to print all permutations of a given string | neveropen', 'views': '334, 905', 'rating': 4.0, 'author': 'neveropen', 'user_id': '0RhatS1pyxInC00YKjjBqQ', 'privacy': 'public', 'start': 0.0, 'dislikes': 227, 'duration': '11:52', 'comments': '116', 'keywords': '', 'thumbnail': 'https://i.ytimg.com/vi/AfxHGNRtFac/default.jpg', 'cc_license': False, 'category_id': 22, 'description': 'Explanation for the Article: https://www.geeksforgeeks.org/write-a-c-program-to-print-all-permutations-of-a-given-string/\n\nThis video is contributed by Sephiri.\n#neveropen', 'encrypted_id': 'AfxHGNRtFac', 'time_created': 1490874673, 'time_updated': None, 'length_seconds': 712, 'end': 712}
