NLTK provides functions for printing all the words in the Brown (or Gutenberg) corpus. But the equivalent function does not seem to work on Wordnet. 

Is there a way to do this through NLTK? If there is not, how might one do it?

This works: 

```
from nltk.corpus import brown as b
print b.words()

```

This causes an AttributeError:

```
from nltk.corpus import wordnet as wn
print wn.words()

```
