Write a code segment that prompts the user for a filename. If the file exists, the program should print its contents on the terminal. Otherwise, it should print an error message.

Code is written in Python

dataobject = DataTransferinFiles ()

Should be just:

dataobject = DataTransferinFiles ()

So the full code:

class DataTransferinFiles ():

def transfer (self, firstfilename, secondfilename):

print ("your first file is=", firstfilename);

print ("your second file is = ", secondfilename)

with open (firstfilename,'r') as filedа ta:

firstfiledata = filedata. readlines ()

print ()

print ("1st file reading complete")

print ()

with open (secondfilename, 'r') as filedа ta:

secondfiledata=filedata. readlines ()

print ("2st file reading complete")

for eachline in firstfiledа ta:

filesecond = open (secondfilename,'a')

filesecond. write ("/n"+eachline + "/n")

print ("1st file transfered in to second file")

for eachline in secondfiledа ta:

filefirst = open (firstfilename)

filefirst. write ("/n"+eachline + "/n")

print ("second file transfered in to first file")

dataobject = DataTransferinFiles ()

firstfilename = input ("enter first file name for transfer")

secondfilename = input ("enter second file name for transfer")

dataobject. transfer (firstfilename, secondfilename)
