精彩摘录

"我从事编程已经太长时间，长到对我来说编程已经是非常乏味的事情了。我写这本书的时候，已经懂得大约 20 种编程语言，而且可以在大约一天或者一个星期内学会一门编程语言(取决于这门语言有多古怪)。现在对我来说编程这件事情已经很无聊，已经谈不上什么兴趣了。当然这不是说编程本身是一件无聊的事情，也不是说你以后也一定会这样觉得，这只是我个人在当前的感觉而已。在这么久的旅程下来我的体会是：编程语言这东西并不重要，重要的是你用这些语言做的事情。事实上我一直知道这一点，不过以前我会周期性地被各种编程语言分神而忘记了这一点。现在我是永远不会忘记这一点了，你也不应该忘记这一点。你学到和用到的编程语"
"Rules For If-Statements 1.Every if-statement must have an else. 2.If this else should never be run because it doesn't make sense, then you must use a die function in the else that prints out an error message and dies, just like we did in the last exercise. This will find many errors. 3.Never nest if"
"If they like control and have a huge beard, they'll tell you to install Linux."
"Hit CTRL-D (^D) and get out of python. > mkdir mystuff > cd mystuff > dir"
"From now on, when you make mistakes write down on a piece of paper what kind of mistake you made. When you go to the next exercise, look at the last mistakes you made and try not to make them in this new one."
"If you're on Windows try python -m pydoc raw_input instead. Get out of pydoc by typing q to quit."
"The argv is the "argument variable", a very standard name in programming, that you will find used in many other languages. This variable holds the arguments you pass to your Python script when you run it. In the exercises you will get to play with this more and see what happens. Line 3 "unpacks" arg"
"You should immediately notice that we import another handy command named exists. This returns True if a file exists, based on its name in a string as an argument. It returns False if not. Did you see that trick I did with cat? It only works on Linux or OSX, on Windows use type to do the same thing."
