2.Write a program that reads a text file and outputs an exact copy to another file. Access the input and output file names from the command line.

3.Same as problem 2, but each line in the output file should be prefixed with its line number. The line number for each should occupy four spaces, right justified.

Programming language: Python 3

infile = open('sample.txt', 'r') source = infile.read() outfile = open('sample2.txt', 'w') outfile.write('sample.txt') outfile.close()

Please use commands similar to these.
