Question

I downloaded the buffy library using pip install pafy and when I run the code, `

import pafy
url = "https://www.youtube.com/watch?v=bMt47wvK6u0"
video = pafy.new(url)
streams = video.streams
print("hello")
for s in streams:
    print(s)

this problem appears

Traceback (most recent call last):
  File "c:\Users\habdn\OneDrive\المستندات\Downloader\import pafy.py", line 1, in <module>
    import pafy
ModuleNotFoundError: No module named 'pafy'
