In this article we will see how we get the time updated value for 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. Updated time will be None if item is not updated after the creation of it.
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 for implementation
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 to get the meta data
6. With the meta data use ‘time_updated’ key this will return time updated value for given item
Below is the implementation
# importing pafy import pafy # url of playlist # 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'] # getting meta data metadata = item['playlist_meta'] # getting time created of item value = metadata['time_updated'] # printing value print("Time Updated : " + str(value)) |
Output :
Time Updated : None
Another example
# importing pafy import pafy # url of playlist # getting playlist playlist = pafy.get_playlist(url) # getting playlist items items = playlist["items"] # selecting single item item = items[2] # getting meta data metadata = item['playlist_meta'] # getting time created of item value = metadata['time_updated'] # printing value print("Time Updated : " + str(value)) |
Output :
Time Updated : None
