更新回答:NLTK适用于2.7井.我有3.2.我卸载了3.2并安装了2.7.现在它的作品!!

我已经安装了NLTK并试图下载NLTK数据.我所做的是按照本网站上的说明进行操作:http://www.nltk.org/data.html

我下载了NLTK,安装了它,然后尝试运行以下代码:

>>> import nltk
>>> nltk.download()

它给了我如下错误信息:

Traceback (most recent call last):
  File "<pyshell#6>", line 1, in <module>
    nltk.download()
AttributeError: 'module' object has no attribute 'download'
 Directory of C:\Python32\Lib\site-packages

都尝试nltk.download()和nltk.downloader(),既给了我的错误信息.

然后我习惯help(nltk)拿出包裹,它显示以下信息:

我有一个表TF与行FILEID,WORD,FREQUENCY.我试图'and'从表中删除所有单词'of''the'.以下是我的查询.它没有做任何事情.

delete from TF
where WORD='of' AND WORD='and' AND WORD='the';
