首先，像其他人一样开始:使用Hello World程序。这很简单，它让他们对程序的布局有了基本的感觉。试着回想一下你第一次编程的时候，以及一些概念有多么困难——从简单开始。

在Hello World之后，继续创建一些基本变量、算术，然后是布尔逻辑和if/else语句。如果你有一本旧的编程教科书，可以查看一些早期的例子，并让他浏览一下。只是不要一下子介绍太多，否则会让人不知所措。

如果他感兴趣，那些小细节不就是好地方吗?使用python时，您已经切断了GUI，这样就不会有困惑了。为什么不选择一个项目，一款游戏或其他东西，然后执行它呢?经典的高低数字猜谜游戏可以简单地从命令行中用20-30行代码(当然取决于语言)实现，并为您提供变量、条件、循环和用户输入。

我强烈推荐John Zelle所著的Python编程:计算机科学介绍第二版。它面向初学者，并处理编程的语义。阅读后，您将能够更快地学习其他语言，因为Zelle的语义vs.语法方法。点击这里查看详情！

I would recommend also watching some screencasts - they are generally created in context of a specific technology not a language, though if there's Python code displayed, that'll do :). The point is - they're created by some good programmers and watching how good programmers program is a good thing. You and your brother could do some peer programming as well, that might be an even better idea. Just don't forget to explain WHY you do something this way and not that way. I think the best way to learn programming is from good examples and try not to even see the bad ones.

Python包VPython—3D Programming for Ordinary Mortal(视频教程)。

代码示例:

from visual import *

floor = box (pos=(0,0,0), length=4, height=0.5, width=4, color=color.blue)
ball = sphere (pos=(0,4,0), radius=1, color=color.red)
ball.velocity = vector(0,-1,0)
dt = 0.01

while 1:
    rate (100)
    ball.pos = ball.pos + ball.velocity*dt
    if ball.y < ball.radius:
        ball.velocity.y = -ball.velocity.y
    else:
        ball.velocity.y = ball.velocity.y - 9.8*dt
