  • Last Updated : 20 Jul, 2020
Geek Week

In this article we will see how we can populate the item to 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. Populate means to fill in the playlist.

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 ‘pafy’ key with it
6. Use populate_from_playlist attribute with this pafy object

In order to do this we use populate_from_playlist attribute with the playlist item’s pafy object



Syntax : playlist_pafy.populate_from_playlist

Argument : It takes no argument

Return : It returns string

Below is the implementation




# importing pafy
import pafy 
    
# url of playlist
url = "https://www.youtube.com / playlist?list = PLqM7alHXFySGqCvcwfqqMrteqWukz9ZoE"
  
# getting playlist
playlist = pafy.get_playlist(url)
  
# getting playlist items
items = playlist["items"]
  
# selecting single item
item = items[1]
  
# getting pafy object
i_pafy = item['pafy']
      
# populating to playlist
value = i_pafy.populate_from_playlist
  
# printing value
print(value)

Output :

bound method BasePafy.populate_from_playlist of Pafy object: AfxHGNRtFac [Write a program to print all permutations of ..]

Another example




# importing pafy
import pafy 
    
# url of playlist
url = "https://www.youtube.com / playlist?list = PLqM7alHXFySE71A2bQdYp37vYr0aReknt"
    
# getting playlist
playlist = pafy.get_playlist(url)
  
# getting playlist items
items = playlist["items"]
  
# selecting single item
item = items[1]
  
# getting pafy object
i_pafy = item['pafy']
      
      
# populating to playlist
value = i_pafy.populate_from_playlist
  
# printing value
print(value)

Output :

bound method BasePafy.populate_from_playlist of Pafy object: WdgAKCnWnwA [Merge Overlapping Intervals | GeeksforGeeks..]
