我们不准备对所有Tk组件一一详细讲解，因为已经有许多关于它们的很好的文章可供参考--不论是从Python网站的Tkinter主题页面还是数量可观的Tcl/Tk印刷品，抑或是在线资源（其中一些可以在附录B中找到）。

37网络编程方面的背景资料和Python中使用套接字的方法，然后介绍如何使用Python

Python is a minimalistic language. One of it's most visible features is that it does not use semicolons nor brackets. Python uses intendation instead.

Python是一种简介的语言，它的最显著的特性之一就是不用使用分号或括号，而是使用回车和空格分隔语句和函数。

Because there is no one standard library for heterogeneous arrays and hash tables (Python dictionaries or "dicts" for short) in C, they are often reimplemented and copied to each new project. This process is messy and error prone. C++ improves the situation with the standard tem- plate library, but the STL can hardly compare to the simplicity and readabil- ity of Python's built-in lists and dicts.

79因为在 C 语言中，没有针对不同数组和哈希表的标准库，所以它们经常需要被重复实现，并被复制到每个新的项目中去，这个过程混乱而且容易产生错误。C++使用标准模版库改进了这种情况，但是标准模版库是很难与Python内建的列表和字典的简洁和易读相提并论的。
