Daily Interview Problem: Reverse Words in a String

Hi, here's your problem today. This problem was recently asked by Facebook:

Given a string, you need to reverse the order of characters in each word within a sentence while still preserving whitespace and initial word order.

Example 1:
Input: "The cat in the hat"
Output: "ehT tac ni eht tah"
Note: In the string, each word is separated by single space and there will not be any extra space in the string.

Here's a starting point:

class Solution:

  def reverseWords(self, str):

    # Fill this in.



print Solution().reverseWords("The cat in the hat")

# ehT tac ni eht tah
