Installation
In order to install pafy we use the command given below

pip install pafy

Note : Pafy is optionally depends on youtube-dl so therefore for more stable usage it is recommended to install youtube-dl before installing pafy. Below is the command to install youtube-dl



pip install youtube_dl

Example 1:
Program to get the number of views on a video




# importing pafy
import pafy 
    
# url of video 
url = "https://www.youtube.com / watch?v = mmjDZGSr7EA"
    
# instant created 
video = pafy.new(url) 
  
# getting number of likes
count = video.viewcount
  
# showing likes
print("View Count : " + str(count))

Output :

View Count : 287205

Example 2:
Program to get the thumb image of a video




# importing pafy
import pafy 
    
# url of video 
url = "https://www.youtube.com / watch?v = mmjDZGSr7EA"
    
# instant created 
video = pafy.new(url) 
  
# getting thumb image
count = video.thumb
  
# showing likes
print("Thumb Image : " + str(count))

Output :

Thumb Image : http://i.ytimg.com/vi/vG2PNdI8axo/default.jpg

Program to get the title of a video




# importing pafy
import pafy 
    
# url of video 
url = "https://www.youtube.com / watch?v = vG2PNdI8axo"
    
# instant created

# getting title
value = video.title
  
# showing likes
print("Title : " + str(value))
