You have already seen quite a few examples of using classes defined in the .NET BCL library; next, you ll learn how to define your own classes. In object-oriented programming, a class should model some concept used within the program or library you are creating. For example, the String class models a collection of characters, and the Process class models an operating-system process. A class is a type, so a class definition starts with the type keyword, followed by the name of the class and the parameters of the class s constructor between parentheses. Next comes an equals sign, followed by a class s member definitions. The most basic member of a class is called a method, which is a function that has access to the parameters of the class. The next example shows a class that represents a user. The user class s constructor takes two parameters: the users name and a hash of the user s password. Your class provides two member methods: Authenticate, which checks whether the user s password is valid; and LogonMessage, which gets a user-specific logon message: open Strangelights.Samples.Helpers // a class that represents a user // it's constructor takes two parameters, the user's // name and a hash of their password type User(name, passwordHash) = // hashs the users password and checks it against // the known hash member x.Authenticate(password) = let hashResult = hash (password, "sha1") passwordHash = hashResult // gets the users logon message member x.LogonMessage() = Printf.sprintf "Hello, %s" name // create a new instance of our user class let user = User("Robert", "AF73C586F66FDC99ABF1EADB2B71C5E46C80C24A")

Summary

n the previous chapter we entered our Python code a line at a time, but now we are going to put the interactive interpreter to the side and start creating Python files. In this chapter we will cover more of the building blocks of Python code, and show you how to use classes to help with creating games. We will also explain how to use the code libraries that come with all installations of Python.

let main() = // authenticate user and print appropriate message if user.Authenticate("badpass") then printfn "%s" (user.LogonMessage()) else printfn "Logon failed" do main()

When people think of functional programming, they often view its statelessness as a fatal flaw without considering its advantages One could argue that since an imperative program is often 90 percent assignment and since a functional program has no assignment, a functional program could be 90 percent shorter However, not many people are convinced by such arguments or attracted to the ascetic world of stateless recursive programming, as John Hughes pointed out in his classic paper Why Functional Programming Matters The functional programmer sounds rather like a medieval monk, denying himself the pleasures of life in the hope that it will make him virtuous John Hughes, Chalmers University of Technology (http://wwwmathchalmersse/~rjmh/Papers/whyfphtml) To see the advantages of functional programming, you must look at what FP permits rather than what it prohibits.

This chapter covered the basics of day-to-day activities within an iteration. All team members should be involved throughout the iteration and should understand their role and responsibilities. If any team members are unsure what they should be doing, the coaches should step in to help them understand their role. The outcome of the iteration should be completed user stories that are unit and acceptance tested. As a result, the features delivered should be of production quality. That doesn t mean the features should be deployed to production more features are most likely needed before that happens. It just means the code could be released to production if needed. This completes your introduction to XP The next section of this book will cover software . tools that you should set up in your development environment to assist you in your Agile development. These tools will provide your team with a unit testing framework, a simulation framework, an automation process, and refactoring assistance. We will start with the unit testing framework: NAnt.

A file containing Python code is called a script. All you need to create scripts is a simple text editor, but it s best to use a Python-aware editor such as SciTE (see Figure 2-1) or IDLE (which comes with the standard distribution of Python). Just save your script with a .py extension, so that your operating system knows that it contains Python. To run a script, you typically just double-click it, or if you prefer the command line, type python followed by a space and the name of your script. Most Python editors will have a shortcut key to run the script you have been editing.
