Python Program to shuffle the words per line of a text fileThis program takes as input a text file and reads each line into a list of words , shuffles the words and writes the line into an output file. The program uses the python library random to perform the shuffle operation on each line of the text document.
The time complexity of the program is O(n) where n is the number of lines in the document including blank lines.

#program to shuffle words that takes as input a text document and
#reads each line ,shuffles it and writes it into a new text file

from docx import Document
import random
class ShuffledWords:
    def __init__(self,inputfilename):
        self.inputfilename=inputfilename
        
#funtion to read a line from  the input file and save it as a list and write to output file       
    def shuffle_words_in_line(self):
        list_of_words=[]
        fin = open(self.inputfilename,'r+')			#opens input file
        fout = open("shuffledwords.txt", "w+")		#opens the output file
        for line in fin.readlines():
            line=line.strip()				#removes %u2018\n%u2019 from each line
            list_of_words=list(line.split(' '))
            random.shuffle(list_of_words)
            shuffledline=' '.join(word for word in list_of_words)
            fout.write( shuffledline + '\n')
        fin.close()
        fout.close()            
        return 1

# main program creates an object of class ShuffledWords
if __name__ == '__main__':
    print("Enter the input filename")
    sw= ShuffledWords(input())
    sw.shuffle_words_in_line()
    print("Done")
