电脑真讨厌。这个提示到底问题出在哪里？
“在命令行的shell提示符下键入python，启动解释器。现在输入
print 'Hello World'，然后按Enter键。你应该可以看到输出的单词Hello World” 这句话运行后都正常。“$ python

这段句子也运行的正常。
“挑选一个编辑器
在我们开始讲述以源文件方式编写Python程序之前，我们需要一个编辑器来写源文件。挑选一个编辑器确实是极其重要的。你挑选一个编辑器就如同你挑选一辆你将购买的轿车一样。一个好的编辑器会帮助你方便地编写Python程序，使你地编程旅程更加舒适，帮助你更加快捷安全地到达目的地（实现目标）。
对于编辑器的基本要求之一是语法加亮功能，利用这一功能，你的Python程序的不同部分被标以不同的颜色，这样你可以更好 看清楚 你的程序，使它的运行显得形象化。”
但是这段话，我根本就找不到去哪里找这个编译器。我执行不了。后面还有更麻烦的问题。
