python中的编码知识整理汇总

问题在平时工作中，遇到了这样的错误：UnicodeDecodeError:'ascii'codeccan'tdecodebyte想必大家也都碰到过，很常见。于是决定对python的编码做一个整理和学习。基础知识在python2.x中，有两种数据类型，unicode和str，这两个都是basestring的子类>>>a='中'>>>type(a)>>>isinstance(a,basestring)True>>>a=u'中'>>>type(a)>>>isin

详解Python if-elif-else知识点

有的时候，一个if…else…还不够用。比如，根据年龄的划分：条件1：18岁或以上：adult条件2：6岁或以上：teenager条件3：6岁以下：kidPythonif-elif-else知识点ifage>=18:print'adult'else:ifage>=6:print'teenager'else:print'kid'这样写出来，我们就得到了一个两层嵌套的if…else…语句。这个逻辑没有问题，但是，如果继续增加条件，比如3岁以下是baby：ifa

AOP 的利器：ASM 3.0 介绍(4)

ASM3.0编程框架ASM通过树这种数据结构来表示复杂的字节码结构，并利用Push模型来对树进行遍历，在遍历过程中对字节码进行修改。所谓的Push模型类似于简单的Visitor设计模式，因为需要处理字节码结构是固定的，所以不需要专门抽象出一种Vistable接口，而只需要提供Visitor接口。所谓Visitor模式和Iterator模式有点类似，它们都被用来遍历一些复杂的数据结构。Visitor相当于用户派出的代表，深入到算法内部，由算法安排访问行程。V
