557. Reverse Words in a String III

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: "Let's take LeetCode contest"
Output: "s'teL ekat edoCteeL tsetnoc"
Note: In the string, each word is separated by single space and there will not be any extra space in the string.

        '''
        splitting the string into an array
        looping through the array and replacing the words with the reverse of the word
        joining the array back into a string, separated with spaces
        '''
        s = s.split()
        for i, word in enumerate(s):
            s[i] = word[::-1]
        return " ".join(s)

        '''
        one-liner

        # return " ".join([i[::-1] for i in s.split()])
