TF-IDF Calculator

Compute TF-IDF scores for each word in each document. Return a list of dictionaries mapping words to their TF-IDF scores.

• TF(word, doc) = count of word in doc / total words in doc
• IDF(word) = log(total docs / docs containing word)

Example

docs = ["the cat sat", "the cat played", "the dog barked"]
tfidf(docs)
# Returns list of 3 dicts with TF-IDF scores
