pip install nltk 之后from nltk.tokenize import RegexpTokenizer仍然报错SyntaxError: invalid syntax 找了好几个小时终于解决了 如果是python2.7版本,那么需要nltk的版本是3.0 pip install nltk==3.0

借助NLTK tokenize.regexp()模块,我们可以通过使用正则表达式从字符串中提取标记RegexpTokenizer()方法。 用法:tokenize.RegexpTokenizer() 返回:Return array of tokens using regular expression 范例1: 在这个例子中,我们使用RegexpTokenizer()借助正则表达式提取令牌流的方法。
