data = f.readlines()

#split the words into array from the line

for line in data:

words = line.split(" ")

l=len(words)

i=0

w1=""

while i<l-1:

#check the words with fn which is i and lastname is i+1

if (words[i] == words[i+1]):

w1=w1+" "+words[i]+" "+words[i+1]

#move to the next

i=i+2

//write the output to the file

f = open("SameName", "w")

f.write(w1)
