Playlist Downloader Project (code) in Python

Playlist Downloader in Python.

About the project: This is a project for a Playlist Downloader in Python. This will be a self-contained script that uses the pytube library to download videos or entire playlists from YouTube.

Before You Run the Code

Install pytube: You'll need to install the pytube library. Open your terminal or command prompt and run the following command:
```
     pip install pytube
     
```
Paste the URL: When you run the script, it will prompt you for the URL of the YouTube playlist you want to download. You can find this URL in your web browser's address bar when you're on the playlist page.

This script will download each video in the playlist to the same directory as the script.

This script provides a complete and interactive Playlist Downloader. When you run it, it will create a new folder with the same name as the playlist's title and save all the downloaded videos inside it.
