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.

Python

 
class Solution:
    def countSegments(self, s):
        """
        :type s: str
        :rtype: int
        """
        a = s.split(" ")
        result = 0
        for i in a:
            if i:
                result += 1
        return result
