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