打开文本文件：

text_file = open('online review data.txt','r',encoding='utf-8')

读取数据：

text = text_file.read()

读取的数据类型：

print (type(text)) print(" ")

打印文本：

print(text) print(" ")

导入所需库：

import jieba

按句子对文本进行分词：

sentences = list(jieba.cut(text, cut_all=False)) print("精确模式: " + " / ".join(sentences))

打印分词结果：

#print(sentences) print(sentences)

import jieba.posseg as pseg tag_filter = ['n'] words_pair = pseg.cut(text) result = [] for word, flag in words_pair: if flag in tag_filter: result.append(word) print("词性过滤完成") print(result)
