Extracting YouTube Links for Songs in a Spotify Playlist

I have written a Python script to extract YouTube links for songs in a Spotify playlist. Regrettably, it seems to fetch only the initial 100 songs out of a total of over 2000 in the playlist. Additionally, when I attempt to run the code for the second time, I encounter a 403 error, signaling a quota limit breach.

As a newbie, any guidance or support you can provide would be greatly appreciated.

Thanks in advance.
