First hint is some of the items in the string are adjacent to a comma, so splitting with the default split() leaves words like "match,"

Second hint is this is an re challenge so you'll likely need to use an 're.search' or 're.match' to find the correct solution to look for words of nb or longer actual characters: r'\w'*6

Bonus, first string2.split() isn't assigned to a variable so it's output is thrown away. The line could be deleted.
