python 3 class:

class Input An object of this class represents information about the input data. This class should implement (at least) the following methods: . init_(self) uses input ) to read in the name of an input file, opens the file, and initializes an attribute of the object with the file object returned by open () word list self : reads in the contents o the input le, splits t into a list o words, remo es any punctuation at either end of the word un tuation characters side he wor si d not e removed), discards any empty strings that may result, and returns the resulting list. class Ngrams An object of this class represents n-gram information about the input list of words. This class should implement (at least) the following methods . init(self) : uses input) to read in the value of n for computing n-grams and initializes an attribute of the object with this value. It also initializes the data structure that will be used to keep track of the number of times each n-gram occurs in the input. . update (self, ngram) updates the count for the n-gram ngram . process wordlist (self, wordlist) processes the list of words wordlist read from the input file to compute the number of times each n-gram occurs in wordlist. print_max_ngrams (self) : prints out the n-grams that have the highest number of occurrences according to the output format specified above (see Output) class Input An object of this class represents information about the input data.
