58. Length of Last Word

题目： https://leetcode.com/problems/length-of-last-word/

难度 : Easy

我的解法：

class Solution(object):
    def lengthOfLastWord(self, s):
        """
        :type s: str
        :rtype: int
        """
        s = s[::-1].strip()
        return s.find(' ') if s.find(' ') != -1 else len(s)

作弊式做法

class Solution(object):
    def lengthOfLastWord(self, s):
        """
        :type s: str
        :rtype: int
        """
        lst = s.split()
        if len(lst) >= 1:
        	return len(lst[-1])
        return 0

split()方法最低可以分0组，split(' ')最低可以分1组

一行解法：
class Solution(object):
    def lengthOfLastWord(self, s):
        """
        :type s: str
        :rtype: int
        """
        return len(s.strip().split(" ")[-1])
