YouTube video to mp3 download using python step by step 

Here's an example of how to download the audio of a YouTube video as an MP3 file using Python:

Install the pytube and pydub libraries using pip:

Copy code

pip install pytube pydub

Import the pytube and pydub libraries in your Python script:

Copy code

from pytube import YouTube

from pydub import AudioSegment

Create a YouTube object with the video URL:

Copy code

yt = YouTube("https://www.youtube.com/watch?v=dQw4w9WgXcQ")

Select the audio stream with the desired file type:

Copy code

audio_stream = yt.streams.filter(only_audio=True, file_extension='mp4').first()

Download the audio stream to a file:

Copy code

audio_stream.download()

Use the pydub library to convert the audio stream from mp4 to mp3:

Copy code

audio = AudioSegment.from_file("audio_stream.mp4", format="mp4")

audio.export("audio_stream.mp3", format="mp3")

This will download the audio of the video in mp3 format in the current working directory.

Please note that the process of converting the video to audio and then converting the audio format uses a lot of resources, so it might take some time to finish the process, also you need to have ffmpeg installed on your machine in order to use pydub library.

You can also use other libraries such as moviepy, moviepy.audio, moviepy.editor and etc.

You can check the official documentation of the pytube and pydub library for more information: https://pypi.org/project/pytube/ and https://pydub.com/
