[LeetCode][Python]434. Number of

Count the number of segments in a string, where a segment is defined to be a contiguous sequence of non-space characters.

Please note that the string does not contain any non-printable characters.

Example:

Input: "Hello, my name is John"
Output: 5

思路：

1. 首先要明白non-space和non-printable的含义。Python不带参数的split()，会把所有空格（空格符、制表符、换行符）当作分隔符。

#!/usr/bin/env python
# -*- coding: UTF-8 -*-
class Solution(object):
    def countSegments(self, s):
        """
        :type s: str
        :rtype: int
        """
        return len(s.split())

if __name__ == '__main__':
    sol = Solution()
    s = "Hello, my name is John"
    print sol.countSegments(s)
