Error message: ValueError: too many values to unpack in Frequecy distribution of NLTK

I am getting error as ValueError: too many values to unpack (expected 2) for the below code. I am not sure whether it is because of too many nouns count.

from nltk.corpus import brown
import nltk

tagged_words = brown.tagged_words(categories='mystery')

for word, tag in tagged_words:
   if any(noun_tag in tag for noun_tag in ['NP', 'NN']):

       nouns=(word,tag)


for word, tag in nouns:
   nouns_freq =nltk.FreqDist(word)

Please suggest

Error:

Traceback (most recent call last):

File "C:\Users\\Word2Vec.py", line 12, in module


for word, tag in nouns:

ValueError: too many values to unpack (expected 2)

The following code will give you the frequency of nouns of the mystery genre in brown corpus.

from nltk.corpus import brown
from nltk import FreqDist

tagged_words = brown.tagged_words(categories='mystery')

# get list of lowercased nouns    
nouns = [word[0].lower() for word in tagged_words if word[1] in ['NP', 'NN']]    
nouns_freq = FreqDist(nouns)
