Given a sentence that consists of some phrases separated by a single house, and a searchWord, examine if searchWord is a prefix of any phrase in sentence.
Return the index of the phrase in sentence (1-indexed) the place searchWord is a prefix of this phrase. If searchWord is a prefix of a couple of phrase, return the index of the primary phrase (minimal index). If there is no such thing as a such phrase return -1.
A prefix of a string s is any main contiguous substring of s.
Right here is my answer:
class Answer(object):
def isPrefixOfWord(self, sentence, searchWord):
"""
:sort sentence: str
:sort searchWord: str
:rtype: int
"""
s = sentence.cut up(" ")
for i, phrase in enumerate(s):
if phrase.startswith(searchWord):
return i + 1
return -1
