The key is the mathematical definition of the factorial, which can be stated as follows: The factorial of 1 is 1 The factorial of a number n greater than 1 is the product of n and the factorial of n 1 As you can see, this definition is exactly equivalent to the one given at the beginning of this section Now, consider how you implement this definition as a function It is actually pretty straightforward, once you understand the definition itself: def factorial(n): if n == 1: return 1 else: return n * factorial(n-1) This is a direct implementation of the definition Just remember that the function call factorial(n) is a different entity from the call factorial(n-1) Let s consider another example Assume you want to calculate powers, just like the built-in function pow, or the operator **.

Before you can add data into a database, it s necessary to create one or many tables to hold it. To create a table, you need to know what you want to store in it, what you want to call it, and what attributes you want to store. For your table people, you want to have name, job, gender, and age columns, as well as a unique id column for possible relationships with other tables. To create a table, you use a syntax like so:

Although BBP slides look dramatically different from conventional slides, the real fruit of your labor is your con dent understanding of what you want to say and how you want to say it. You have expanded the capability of Microsoft Of ce PowerPoint 2007 beyond a tool for designing slides into a tool that helps your audience understand new information more effectively. Because you use the story template as a thinking tool to organize your ideas and structure a story, you can then use PowerPoint as a creative tool to express yourself with a limitless range of media possibilities. When you open your BBP presentation, you actually have a sophisticated media toolkit that blends your clear ideas and story with the delivery technology. Now it s time to use that toolkit to bring your story to life.

CREATE TABLE table_name ( column_name data_type options, column_name data_type options, ..., ... )

Therefore, for your people table, you d use this syntax:

You can define the (integer) power of a number in several different ways, but let s start with a simple one: power(x,n) (x to the power of n) is the number x multiplied by itself n-1 times (so that x is used as a factor n times) So power(2,3) is 2 multiplied with itself twice, or 2 2 2 = 8 This is easy to implement:.

CREATE TABLE people ( id integer primary key, name varchar(50), job varchar(50), gender varchar(6), age integer)

10

This SQL command creates a people table and gives it five columns. The data types for the name, job, and gender columns are all VARCHARs, meaning they re variable-length character fields. In basic terms, it means they can contain strings. The number in brackets refers to the maximum length of that string, so the name column can hold a maximum of 50 characters.

Note SQLite is a reasonably pragmatic database, and it ignores most conventions relating to data types

The term production refers to the point when lmmakers capture the live action of actors on lm. Film directors spend a great deal of time setting up scenes and lming the action many times so that they ll be able to use the best performances in the nal cut. But you don t have that luxury in your PowerPoint production because you re presenting in a live environment, which means that you typically get only a single shot at engaging the audience. Managing the complex mix of elements in a live presentation can be challenging, but you already have rm control over the projected media, spoken words, and printed handouts in your BBP presentation. As you use the PowerPoint le to deliver your presentation, a set of ground rules can help keep the experience in balance.
