How does the answer to the third question is 6 , I am getting the answer as 5 . Below is the code I used.
def myTokenzier(sentence):
words=tokenizer.tokenize(sentence.lower())
words=[w for w in words if w not in sw]
return words
cv=CountVectorizer(tokenizer=myTokenzier,ngram_range=(3,3))
vc=cv.fit_transform([’#Coding Blocks is a great source to learn @machine_learning ']).toarray()
print(len(vc[0]))
print(cv.vocabulary_)
