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.

class Solution(object):
def reverseWords(self, s):
“””
:type s: str
:rtype: str
“””
l = s.split()
i =0
for x in l:
l[i]=l[i][::-1]
i = i +1
str = ” “.join(l)
return str
