#Here is the Python program you requested.

class Solution:
     def reverseWords(self, s):
         """
         :type s: str
         :rtype: str
         """
         words = s.split(" ")
         output = ""
         
         for i, word in enumerate(words):
             output += word[::-1]
             if i != len(words) - 1:
                 output += " "
         
         return output
