text_corpus = [
"Human machine interface for lab abc computer applications",
"A survey of user opinion of computer system response time",
"The EPS user interface management system"
]
stop_list=set('for a of the and to in'.split(' '))
texts = [[word for word in document.lower().split() if word not in stop_list]for document in text_corpus]
主要是最后一行,应该是先执行for document in text_corpus ,也就是从text_corpus中每次去除一个字符串也就是doucument,然后把这个字符串document放到前面执行,然后前面一长串我就不知道咋执行的
