Thanks for the video! Expanding on your last solution, you could slice the string with a -1 step in the same line to obtain the same result like this:

class Solution:
def reverseWords(self, s: str) -> str:
return ' '.join(s.split()[::-1])

However, i believe your use of reversed is definitely cleaner to read. Also, thank you for showing multiple solutions in the same video. I enjoyed that!
