#!/usr/bin/env python
# -*- coding: utf-8 -*-
主要说下编码的处理
1、ASCII编码
每个字符用一个字节来表示,即每个字符只有8位 总共为255个数组 包含了大小写字母、数字和符号
2、unicode编码
统一了所有国家的字符 中文的字符太多了,很显然不能用一个字节来表示,于是出现了这个编码,每个字符用2个字节来表示 即一共可以便是2的16次方字符 差不多能把中文的字符给表示完
3、utf-8编码
中文中有的用不了2个字节 太浪费空间 于是出现了在uncode基础上修改的utf-8 使用可以自动调制长短的编码 一个字符可以用1-6个字符来表示
后续:计算中只能处理数字, 我们看到的都是转换编码之后的数据,在正式的存储的时候最终都是转化成数字进行存储的传输的
