I am trying to write a function named custom_preprocessor that can count the number of words that contain prefixes and suffixes. Later, the function will be call at the code below. #calculate tf-idf score using sklearn tfIdfTransformer = TfidfTransformer(use_idf=True) countVectorizer = CountVectorizer(tokenizer=tokenize, preprocessor = custom_preprocessor) wordCount = countVectorizer.fit_transform(token_dict.values()) newTfIdf = tfIdfTransformer.fit_transform(wordCount) Can you help to write the function using python? Thank you.

Question

I am trying to write a function named custom_preprocessor that can count the number of words that contain prefixes and suffixes.

Later, the function will be call at the code below.

#calculate tf-idf score using sklearn

tfIdfTransformer = TfidfTransformer(use_idf=True)

countVectorizer = CountVectorizer(tokenizer=tokenize, preprocessor custom_preprocessor)

wordCount = countVectorizer.fit_transform(token_dict.values())

newTfIdf = tfIdfTransformer.fit_transform(wordCount)

Can you help to write the function using python? Thank you.
