Question

Your task is to process a file containing the text of a book available as a file as follows:

A function GetGoing(filename) that will take a file name as a parameter. The function will read the contents of the file into a string. Then it prints the number of characters and the number of words in the file. The function also returns the content of the file as a Python list of words in the text file.

A function FindMatches(keywordlist, textlist): The parameter keywordlist contains a list of words. The parameter textlist contains text from a book as a list of words. For each word in keywordlist, the function will print the number of times it occurs in textlist. Nothing is returned.

If you implemented the functions correctly then the following program:

booktext = GetGoing('constitution.txt') FindMatches (['War', 'Peace', 'Power'], booktext) Will read the file "constitution.txt" and print something like the following:

The number of characters is: 42761

The number of words is: 7078

The number of occurrences of War is: 4

The number of occurrences of Peace is: 2

The number of occurrences of Power is: 11

In case of any query do comment. Please rate answer as well. Thanks

Note: I have used arbitrary file with general text. You should use your file as input.

Code:

#function to count number of characters, words in a given file and returns a list of words

def GetGoing(filename):

    file = open(filename)

    numbrOfCharacters =0

    numberOfWords = 0

    WordList = []

    #iterate over file line by line

    for line in file:

        #split the line into words

        words = line.strip().split()

        #add counn of words to numberOfWords

        numberOfWords = numberOfWords + len(words)

        #find number of characters in each word and add it to numbrOfCharacters

        numbrOfCharacters = numbrOfCharacters + sum(len(word) for word in words)

        #append each word from a line to WordList

        for word in words:

            WordList.append(word)

    #display the result

    print("The number of characters: ", numbrOfCharacters)

    print("The number of Words: ", numberOfWords)

   

    #return the list of words

    return WordList

#find matches for keywords given in textlist

def FindMatches(keywordlist, textlist):

    for keyword in keywordlist:

            keyword = keyword.lower()

            print ("The number of occurrences of {} is: {}".format(keyword,len([i for i, s in enumerate(textlist) if s == keyword])))

#main

booktext = GetGoing("constitution.txt")

FindMatches (['War', 'Peace', 'Power'], booktext)

Input file used:

main.py constitution.txt 1 this is a test for war including peace in to generate power 2 power is again a illustrated enemy of peace.
