Choice is another function that you have been using, perhaps without realising it. Its argument is a list of items, and the processing it does is to select one at random. Its output is an item from the list, which it returns. If you find yourself writing the same code in multiple parts of a program, or using copy and paste, you should think about putting the repeated code into your own function. There are so many functions that if all of them were available at once, it would be overwhelming to the programmer.
Then you test if the variable is within the range of the board. Finally, you check to see if that space is actually free to take a symbol. Only when this final test is passed do you actually make the move on the board and set the variable correct_number to true, which stops the while loop from repeating. Otherwise, a hopefully helpful error message is relayed to the user. The play() function orchestrates the whole game. First the board is printed out, which, as mentioned before, contains the square numbering identification information.
To use a function, you call it by entering its name followed by (). Figure 2-7: Functions are little machines that process inputs to produce an output. Functions may take arguments (sometimes called parameters), which are a way of supplying data to them. Think of them as the raw materials into, or the controls that adjust, the function machine. Imagine a machine that makes different pasta shapes; its arguments might be raw pasta and a setting that determines what shape it produces. Arguments can be a variable (which may change as a program runs) or something hard-coded (written directly into the program by the programmer and never changed) in the program itself.
