Given a sentence that consists of some words separated by a single space, and a searchWord, check if searchWord is a prefix of any word in sentence.

Return the index of the word in sentence (1-indexed) where searchWord is a prefix of this word. If searchWord is a prefix of more than one word, return the index of the first word (minimum index). If there is no such word return -1.

A prefix of a string s is any leading contiguous substring of s.

Here is solution:

class Solution(object):
 def isPrefixOfWord(self, sentence, searchWord):
 """
 :type sentence: str
 :type searchWord: str
 :rtype: int
 """

 s = sentence.split(" ")

 for i, word in enumerate(s):
 if word.startswith(searchWord):
 return i + 1


 return -1
