nltk tagged_words unexpected argument

I am trying to learn NLTK by following instructions in a book. The code is:

from nltk.corpus import brown
brown_news_tagged = brown.tagged_words(categories='news', tagsets='universal')

However, the error I get is: tagged_words() got an unexpected keyword argument 'tagsets'

The correct argument (I think) for python 2.7.8 is [now?] simplify_tags=...

Here are a few reasons why this could be happening:

If you choose to use Python 3 and the alpha version of NLTK 3.0, you can verify the availability of the tagset argument by using the following commands on a command line:

python3
>>> from nltk.corpus import brown
>>> import inspect
>>> inspect.getargspec(brown.tagged_words)

After running those commands, we can see that the tagset parameter/argument is available:

ArgSpec(args=['self', 'fileids', 'categories', 'tagset'], varargs=None, keywords=None, defaults=(None, None, None))

Looking back at the NLTK book in Chapter 5, we can also see that the examples given in relation to the universal option indeed uses tagset (singular rather than plural) in order to obtain the desired results.
