Video2mp3 downloader from youtube video url using python

By Suresh Mahto

This Python script uses Pytube to download MP3 audio from a YouTube video provided by the user's input URL and saves it in the specified or current directory.

In the provided Python project, the code is designed to download audio from a YouTube video and save it as an MP3 file. Here's a breakdown of the key components and functionality:

1. Importing Libraries: The project begins by importing the necessary libraries. pytube is imported to interact with YouTube and os to work with the operating system's file system.

2. User Input: The user is prompted to enter the URL of the YouTube video they want to download. This input is captured using the input function and stored in the variable yt.

3. Extracting Audio Stream: The code then extracts the audio stream from the YouTube video. It filters the available streams to select the one that contains only audio using yt.streams.filter(only_audio=True).first() and stores it in the variable video.

4. Destination Path: The user is prompted to specify the path where they want to save the MP3 file. If the user presses Enter without entering a path, the current directory is used as the default destination, and this information is stored in the destination variable.

5. Downloading and Renaming: The code proceeds to download the audio stream using the video.download() method. It specifies the output path as the destination path provided by the user. After the download is complete, the downloaded file is renamed with a ".mp3" extension using the os.rename() function, ensuring that the file is saved as an MP3 file.

6. Success Message: Finally, a success message is printed to inform the user that the MP3 file has been successfully downloaded. This message includes the title of the YouTube video, which is obtained from yt.title.

In summary, this Python project leverages the pytube library to download the audio from a YouTube video, allowing the user to specify a destination path for the resulting MP3 file. It provides a user-friendly way to download and convert YouTube video audio into MP3 format.
