在函数print_file_stats中新增一个名为stop_words的变量,如下所示: stop_words = {'the', 'and', 'i', 'to', 'of', 'a', 'you', 'my', 'that', 'in'} 当然,你可根据自已的喜好修改排除词集合。现在,修改程序的代码,在计算所有统计数据时,都将stop_list中的单词排除在外。 5.(较难)函数pri...

❶ re.findall 函数返回一个字符串列表,里面的元素是正则表达式的全部非重叠匹配。 ❷ self.words 中保存的是 .findall 函数返回的结果,因此直接返回指定索引位上的单词。 ❸ 为了完善序列协议,我们实现了 __len__ 方法;不过,为了让对象可以迭代,没必要实现这个方法。 ❹ reprlib.repr 这个实用函数用于生...
应用场景1:在使用jieba.analyse提取高频词时,可以事先把停用词存入stopwords.txt文件,然后用以下语句设置停用词:jieba.analyse.set_stop_words('stopwords.txt') 这样提取出的高频词就不会出现停用词了。应用场景2:在使用wordcloud画词云图时,可以设置WordCloud对象的参数stopwords,把需要设置的停用词放到这个参数里(...

most engines are programmed to remove certain words from any index entry. The list of words that are not to be added is called a stop list. Stop words are deemed irrelevant for searching purposes because they occur frequently in the language for which the indexing engine has been tuned. In...
