In python

For example, when prompted, if the user specifies"sampleprogram.py" and that file contains:

#Sample program

Print("This is a sample program")

Your program will produce the file named "ln_sampleprogram.py" and it will contain:

#sample program

Print("This is a sample program")

1. linenumbers.py) Write a program that asks the user for the name of a file. The program should write the contents of this input file to an output file. In the output file, each line should be preceded with a line number followed by a colon. The output file will have the same name as the input filename, preceded by "1n_" (for linenumbers, so if the selected input file is myfile.txt, the output file would be called 1n_myfile.txt). Be sure to use Try/Except to catch all exceptions
