Question

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.

Answer 1

Answer:

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 filedata:

firstfiledata= filedata.readlines()

print()

print("1st file reading complete")

print()

with open(secondfilename, 'r')as filedata:

secondfiledata=filedata.readlines()

print("2st file reading complete")

for eachline in firstfiledata:

filesecond = open(secondfilename,'a')

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

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

for eachline in secondfiledata:

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)
