有一本维基百科非常适合学习python。

我不知道其他语言的维基百科是怎样的，但我个人是从2007年2月的维基百科上学习python的

Ps -如果你不熟悉维基书，它基本上是维基百科版本的书籍创作。这有点难以描述，但如果你看了几本书你就会明白它是如何工作的

我认为一旦他掌握了基本知识(变量，循环等)，你应该试着帮助他找到他感兴趣的具体内容，并帮助他学习实现这一目标的必要条件。我知道如果我对某件事感兴趣，我会更倾向于去做，也更有动力去做。同时，确保让他在一些更棘手的问题上挣扎，没有什么比你自己解决问题的那一刻更令人满足的了。

一些额外的信息可以附加到Jason Pratt之前关于Alice的帖子中…具体来说，是一个讲故事的爱丽丝变体。

虽然这项研究针对的是中学女生，但你可能会觉得凯特琳·凯莱赫撰写的白皮书很有趣。

Something you should be very mindful of while teaching your brother to program is for him not to rely too heavily on you. Often when I find myself helping others they will begin to think of me as answer book to all of their questions and instead of experimenting to find an answer they simply ask me. Often the best teacher is experimentation and every time your brother has a question like "What will happen if I add 2 to a string?" you should tell him to try it out and see for himself. Also I have noticed that when I cannot get a concept through to someone, it helps to see some sample code where we can look at each segment individually and explain it piece by piece. As a side note people new to programming often have trouble with the idea of object oriented programming, they will say they understand it when you teach it to them but will not get a clear concept of it until actually implementing it.

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

There have already been a bunch of great answers, but for an absolute beginner, I would wholeheartedly recommend Hackety Hack. It was created by the unreasonably prolific why_the_lucky_stiff specifically to provide a BASIC/LOGO/Pascal-like environment for new programmers to experiment in. It's essentially a slick Ruby IDE with some great libraries (flash video, IM, web server) and interactive lessons. It makes a good pitch for programming, as it chose lessons that do fun, useful things. "Hello, world" may not impress right off the bat, but creating a custom IM client in 20 minutes can inspire someone to keep learning. Have fun!
