By the way, what is a "function"? Here are the important ideas about functions:
 
* A function encapsulates a useful bit of work and gives that work a name.
* Functions are sort of like functions in math class. You provide input to a function and it produces output. TheFor example, the <code>type</code> function takes data as an input, and produces what type of data the data is (e.g. an integer or a float) as output.
* To use a function, write the name of the function, followed by an open parenthesis, then what the function needs as input (we call that input the <b>arguments</b> to the function), and then a close parenthesis.
* Programmers have a lot of slang around functions. They'll say that functions "take" arguments, or that they "give" or "pass" arguments to a function. "call" and "invoke" are both synonyms for using a function.
