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.

Example:

Input: "Hello World"
Output: 5

Solution:

class Solution(object):
    def lengthOfLastWord(self, s):
        """
        :type s: str
        :rtype: int
        """
        container = []
        flush = 0
        for i in range(len(s)):
            if s[i] == ' ':
                flush = 1
            else:
                if flush == 1:
                    container = []
                    flush = 0
                container.append(s[i])
        return len(container)
