class Solution(object):
    def countSegments(self, s):
        """
        :type s: str
        :rtype: int
        """
        s = s.split()
        
        return len(s)

 split ()  is sliced by specifying a string delimiter, if the parameter value is specified num, num + 1 sub-string is separated.

str - separator, default for all null characters, including spaces, linefeed (\ n-), tab (\ t), etc.
