最后一个单词的长度

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

Description

Given a string s consists of upper/lower-case alphabets and empty space characters ‘ ‘, return the length of last word in the string.

If the last word does not exist, return 0.

Note: A word is defined as a character sequence consists of non-space characters only.

这个题没什么说的，返回一个字符串中最后一个单词的长度，没有的话则返回0，感觉用 python 做像作弊一样。

Example

1
2
Input: "Hello World"
Output: 5

def lengthOfLastWord(s):
    """
    :type s: str
    :rtype: int
    """
    return len(s.strip().split(' ')[-1]) if s else 0
