Tagging a single word with the nltk pos tagger tags each letter instead of the word

Question

I\'m try to tag a single word with the nltk pos tagger:

word = \"going\"
pos = nltk.pos_tag(word)
print pos

But the output is this:

Answer 1

>>> word = 'going'
>>> word = nltk.word_tokenize(word)
>>> l1 = nltk.pos_tag(word)
>>> l1
[('going', 'VBG')]
