I'm guessing that you are following someone else's blog and have failed 
one of two things:

- understand that what was meant by the author was that you were assumed 
to have a function in mind to use for a programming strategy being 
illustrated

- or you were copying and pasting only part of a blog and failed to 
paste in the code from above where there was earlier code defining 
`my_function`
