使用Wordnet Synset的定义方法未获得所需的输出

Question

 from nltk.corpus import wordnet 
 syn=wordnet.synsets('cookbook')[0]
 print syn.definition

预期产量：

'a book of recipes and cooking directions'

实际输出：

bound method Synset.definition of Synset('cookbook.n.01')

我无法在代码中查明导致实际输出与预期输出之间存在差异的错误。

Answer 1

>>> from nltk.corpus import wordnet as wn
>>> wn.synsets('dog')[0]
Synset('dog.n.01')
>>> wn.synsets('dog')[0].definition
<bound method Synset.definition of Synset('dog.n.01')>
>>> wn.synsets('dog')[0].definition()
u'a member of the genus Canis (probably descended from the common wolf) that has been domesticated by man since prehistoric times; occurs in many breeds'

这是因为Synset对象属性已更改为Synset函数，请参见https://github.com/nltk/nltk/commit/ba8ab7e23ea2b8d61029484098fd62d5986acd9c
