In python, using this coding skeleton:

For example:

## skeleton code for RobCo Advertising Adstravaganza! ## Initial Commit: when I'm done, I can go eat some Fancy Lads Snack Cakes, ## maybe drink some cola. Better check in my code first RCK - def open file() ' ' "prompt for file name, open file, return file pointer"' ## Some lines to help with formatting ## filename = input ("Input a file name : ") ## print ("Unable to open file.
