15) Write a general function script to search any text file whose name you input (ie. "C:/my_files/moby_dick.txt") and any character string (ie. "Ishmael") and a name of an output file (ie. "C:/my_files/ishmael.txt") that will search the text file for any line with an instance of that word, numbers each line, and then outputs any line of text that has that character string. Show me your script for this function. Pick a different Project Gutenberg text and a different word and show the output.
