Hooray! You now have the tools to write
reusable functions rather than just one off bits of code.
You should now be able to define functions with appropriate names for formal parameters,
identify formal parameters and parameter values in our code sample,
and predict the return value of a function given sample parameter values.
I'm going to assume that you've managed to work your way
through the exercises we've given you for this lesson.
So, by the power vested in me by the University of Michigan and by Coursera,
I hereby dub you programmer with all the privileges and responsibilities that entails.
Let's finish with a joke about functions.
Why did the function stop calling each other?
Because they had too many arguments. See you next time.
