python统计字符串中每个单词出现的次数_python中每个单词出现的次数是一组字符串？...

你可以这样得到你的分数：import re

sentence = list()

sentence.append(" hello my name is John")

sentence.append("good morning I am John")

sentence.append("hello I am Smith")

value = dict()

for sentenceC in sentence:

for word in sentenceC.strip().split(" "): # split with whitespace

try:

value[word.lower()] += 1

except KeyError:

value[word.lower()] = 1

print (value)

score = dict()

number = 1

for sentenceC in sentence:

for word in sentenceC.strip().split(" "): # split with whitespace

try:

score[number] += value[word.lower()]

except KeyError:

score[number] = value[word.lower()]

number += 1

print score

#output: {1: 7, 2: 8, 3: 7}
