MakcuM [25]

import os

import nltk

import zipfile

from nltk. corpus import gutenberg

from nltk. text import Text

def findWordFreq(text, word):

   textfreq = nltk. FreqDist(text)

   wordfreq = nltk.FreqDist(word)

   maxfreq = max(textfreq)

   return wordfreq, maxfreq

if -_name__ == '__main__':

   text = input()

   word = input()

   if not os.path.exists(os.getcwd() + "/nltk_data"):

       with zipfile.ZipFile("nltk_data.zip", 'r') as zip_ref:

           zip_ref.extractall(os.getcwd())

   os.environ['NLTK_DATA'] = os.getcwd() + "/nltk_data"

   text = Text(gutenberg.words (text))

   word_freq, max_freq = findWordFreq(text, word)

   print(word_freq)

   print(max_freq)

Explanation:

The natural language package in python is used to get and analyse word from voice input. The python code above get words from a zipfile extract, and the 'findWordFreq' function gets the word count and the maximum number of alphabet used in the word distribution.

Therefore the invader won’t be able to predict and response to that number. Because of the authentication protocol, that makes use of a classical cryptosystem thereby resulting into the possibility of an argument such that key finding is attainable via invader.
