（首页）开始编程之旅 翻译自Lee Harr的Start Programming

本文是使用pygsear+pygame作为开发环境，以初级用户角度来分步分阶段学习PYTHON基本概念，并以小游戏开发项目为具体案例，介绍的十分详细。编写风格清新朴实，没有象一般教科书那样枯燥，极其适合初级用户来激发兴趣时使用。

1. StartProgramming-1-9 练习Exercises

1. Play the practice.py game to get used to moving the penguin around. Read the comments at the start of the file to see how to play. (Hint)
2. You made pete move in a square. Now make him go in a rectangle that is twice as wide as it is high. (Hint)
3. Now see if you can make pete go in a triangle. (Hint)
4. Use a variable distance to make pete walk in a square or triangular spiral. (Hint)
5. Make two different loops -- one to draw a pentagon and one to draw a five-pointed star. (Hint)
6. Turn exercise 4 in to both a for loop and a while loop. (Hint)
7. Create functions for triangle and pentagon like we made for square. Make the functions take a parameter for the length of a side. (Hint)
8. Create a function which takes a sequence of strings and writes them around the edges of a polygon with one side for each string. (Hint)
9. Create a function which takes a sequence of strings and writes each one on a separate line, one above the next. (Hint)
