Howdy, today we'll create a program by python in 5 line can download YouTube videos, so let's get started.

Pre-requisites

you'll need :

• python is installed, if you don't install it visit this link https://www.python.org/downloads/

Let's Begin

We'll create two files, video.py & audio.py

video.py

This file will download your video with pictures & audio

audio.py

And This'll download the video only with audio.

Open your favorite editor, and type

$ touch video.py audio.py

We're going to install two packages

pafy & youtube.dl

so in terminal

$ pip install pafy youtube.dl

Little remains, in video.py we'll import pafy

from pafy import new

new is a function download your video by add the URL on it, so create url variable and it's well be input

url = input("Enter the url: ")

now create video variable and it's value is new function

video = new(url)

the video has different quality, we want the best quality, define new variable

dl = video.getbest()
dl.download()

you can test it

$ py video.py

now, go to audio.py, it's like video.py but has some differences

from pafy import new
url = input("Enter the link: ")
video = new(url)

let's define audio variable

audio = video.audiostreams
audio[0].download()

that's it, you can now go to YouTube and download your favorite video/s.

good bye.
