Write a script named numberlines. py. this script creates a program listing from a source program. this script should: prompt the user for the names of two files. the input filename could be the name of the script itself, but be careful to use a different output filename! the script copies the lines of text from the input file to the output file, numbering each line as it goes. the line numbers should be right-justified in 4 columns, so that the format of a line in the output file looks like this example: 1> this is the first line of text.
