Instructions Forum Tutoring Problem program. Write a function concatenate_files(filename1, filename2, new filename) that concatenates the text from two source files such that the text from the file named by argument filename 2 follows the text from filename1. The concatenated text is written to a new file with the name given by new_filename. Your function O must not return anything. We have provided sample input files named part1.txt and part2.txt containing a portion of the text from the novel Alice in Wonderland to test your function.

Consider the following Python code :

import shutil; #importing the module for concatenating purpose.
print("Please enter 'E' for exit.");
filename1 = input("Please enter first file name to concatenate: "); #getting first file to concatenate.
if filename1 == 'E': #checking if user wants to exit or not.
exit(); #used for exit the program
else:
filename2 = input("Please enter second file name to concatenate: "); #getting second file to concatenate.
filename3 = input("Create a new file to concatenate content of two files inside this file: ");
print();
print("concatenating the content of two file in",filename3);
with open(filename3, "wb") as wfd: #code for concatenating two files in third file.
for f in [filename1, filename2]:
with open(f, "rb") as fd:
shutil.copyfileobj(fd, wfd, 1024*1024*10);
print("\nContent concatenated successfully.!");
print("Want to see ? (yes/N): "); #used for checking correct result.
check = input();
if check == 'N':
exit();
else:
print();
c = open(filename3, "r");
print(c.read());
c.close();

Consider that the filename1 file contains "Hello" and the filename2 file contains"World".

Output of the above code will be : HelloWorld

The above python code will concatenate the content of filename1 and filename2 into filename3.The above python code if properly working and is concatenating the contents properly.
