python expert for developing the Cocke-Younger-Kasami algorithm for sentences

You should create a Chomsky Normal Form (CNF) grammar for given sentences and then write below program with those sentences.

Program shoulddo this:

Load the CNF grammar.
Read in the example sentences,
For each example sentence, output to a file:
o the sentence itself
o the simple bracketed structure parse(s) based on your implementation of
the CKY algorithm, and
o the number of parses for that sentence.

Should run the code in python as belows:

my_CKYparser.{py|java|etc} <grammar_filename> <sentence_filename> <output_filename>

o <grammar_filename> is the name of the file holding grammar rules in the in
Chomsky Normal Form.
o <test_sentence_filename> is the name of the file containing the four test
sentences (provided to you) to parse with your algorithm.
o <output_filename> is the name of the file where your system will write the
parses and over the test sentences.
