Write a program diff.py that takes two file names from the command line. The file names may NOT have spaces in them! It then writes either files differ or files are the same.

Example: the user may run your program thus:

python diff.py file1.txt file2.txt

Method: open the files, and read their lines. Then compare their lists of lines.

CODE GIVEN:

''' Takes two filenames from the command line, and determines if the files have the same content. '''

import sys

if len(sys.argv) != 3: print('Usage: python diff.py ') sys.exit(1)

file_name1 = sys.argv[1]

# ... write the rest of your code here
