To run the Python script on Windows OS, follow these steps:

1. Install Python: If you don't already have Python installed on your system, you can download it from the official website at **https://www.python.org/downloads/**. Choose the latest version of Python 3.x, download and run the installer, and follow the prompts to install Python.
2. Install Required Libraries: The script requires the requests and beautifulsoup4 libraries, which you can install using pip. Open a command prompt and type the following command:

pip install requests beautifulsoup4

This will install both libraries.

1. Save the Script: Copy the script into a text editor, such as Notepad or Visual Studio Code, and save it with a .py extension. For example, you can save it as download_mp3.py.
2. Open a Command Prompt: Open a command prompt by pressing the Windows Key + R on your keyboard, typing cmd in the Run dialog box, and then pressing Enter.
3. Navigate to the Script Directory: Use the cd command to navigate to the directory where the script is saved. For example, if you saved the script in the Downloads folder, type:

cd C:\\Users\\YourUserName\\Downloads

4. Run the Script: Once you are in the directory where the script is saved, type the following command to run the script:
