Question

def getResponse(neighbors):
classVotes = {}
for x in range(len(neighbors)):
response = neighbors[x][-1]
if response in classVotes:
classVotes[response] += 1
else:
classVotes[response] = 1
sortedVotes = sorted(classVotes.iteritems(), key=operator.itemgetter(1), reverse=True)
return sortedVotes[0][0]

Answer 1

def getResponse(neighbors):#给结果搞个字典classVotes={}#把每个neighor都循环一遍for x in range(len(neighbors)):response = neighbors[x][-1]print responseif response in classVotes:classVotes[response]+=1print classVoteselse:classVotes[response] =1sortedVotes = sorted(classVotes.iteritems(),key = operator.itemgetter(1),reverse = True) #reverse是按降序方式排序  return sortedVotes[0][0]
