This is a Python script that can be used to download YouTube videos or playlists. The script uses the yt_dlp library, which is a fork of youtube-dl. It can handle different types of YouTube URLs and allows the user to choose between downloading a video or a playlist.

Installation

To use this script, you need to have Python 3 installed on your system. You can download Python from the official website: https://www.python.org/downloads/

You also need to install the yt_dlp library. You can install it using pip:

pip install yt-dlp

Usage

To use the script, open a terminal or command prompt and navigate to the directory where the script is located. Then, run the script with the following command:

python youtube_downloader.py "<url>" --download <type>

Replace <url> with the URL of the YouTube video or playlist that you want to download. Replace <type> with either video or playlist, depending on what you want to download. For example, to download a video with the URL https://www.youtube.com/watch?v=5PS2p1AZzFY, run the following command:

python youtube_downloader.py "https://www.youtube.com/watch?v=5PS2p1AZzFY" 
--download video

To download a playlist with the URL https://www.youtube.com/playlist?list=PLXmi76euGSyyq1nw21U1M4tTsM0Zysayk, run the following command:

python youtube_downloader.py 
"https://www.youtube.com/playlist?list=PLXmi76euGSyyq1nw21U1M4tTsM0Zysayk" 
--download playlist

If the URL is in the format https://www.youtube.com/watch?v=5PS2p1AZzFY&list=PLXmi76euGSyyq1nw21U1M4tTsM0Zysayk&index=4, the user will be prompted to choose between downloading a video or a playlist.

Before each video is downloaded, the script checks to see if it already exists in the Downloads folder and skips it if it does. The downloaded videos or playlists are saved in a folder called Downloads in the same directory as the script.

Conclusion

That's it! You should now be able to download YouTube videos and playlists using this Python script. If you encounter any issues or have any questions, feel free to open an issue in the GitHub repository or contact the author directly.
