Download the 'youtube$\_$comments$\_$scientists.csv$\text{'}$ file. CSV represents 'comma$-$separated values'. This file contains three columns: $[$Name$,$ Comment, Like Count$].$ Extract all unique words from the comments. You can split words by $"",",",".","-","?","!",$ etc. Sort all unique words by the number of appearances. Find the top $10$ popular scientists' names suggested by the user comments.

This is a more open$-$ended question. You may have noticed that there could be spelling mistakes in those scientists' names, and therefore one name could be found as several different words. You can address this issue and resolve it through coding, but this is not mandatory. Best coding practices are always appreciated!
