python的str,unicode对象的encode和decode方法 python中的str对象其实就是"8-bit string" ,字节字符串,本质上类似java中的byte[]. 而python中的unicode对象应该才是等同于java中的String对象,或本质上是java的char[]. 对于 s="你好" u=u"你好" s="你好" u=u"你好" 1. s.decode方法和u.enc…

对于encode和decode,笔者也是根据自己的理解,有不对的地方还请多多指点. 编码的理解: 1.编码:utf-8,utf-16,gbk,gb2312,gb18030等,编码为了便于理解,可以把它当做一个算法,用于加密和解密.基类编码字符集:unicode等,基类编码字符集可以理解为明文.其他编码字符集: ANSCII,汉字等,其他类编码字符集可以理解为密文.三者的关系是明文用算法加密成密文,密文用算法解密成明文. 2.Python 默认脚本文件都是 ANSCII 的,当代码中有非 ANSC…

一. 编码 1. ASCII编码 ASCII是最早的计算机编码,包含了英文字母(大小写),数字,标点等特殊符号,一共128个码位,最多只能用8位来表示(一个字节),ASCLL码最多256个位置,无法提供中国的汉字. 2. GBK编码 GBK是国标码,占两个字节(16位),虽然位置增多了,但还是无法将汉字全部存储. 3. unicode unicode是万国码,占4个字节(32位),有40多亿个位置,远远大于中国的汉字数.太浪费. 4. utf-8 utf-8是目前使用最多的编码,每个字符至少占8…

字符串在Python内部的表示是unicode编码,因此,在做编码转换时,通常需要以unicode作为中间编码,即先将其他编码的字符串解码(decode)成unicode,再从unicode编码(encode)成另一种编码. decode的作用是将其他编码的字符串转换成unicode编码,如str1.decode('gb2312'),表示将gb2312编码的字符串str1转换成unicode编码. encode的作用是将unicode编码转换成其他编码的字符串,如str2.encode('gb2…

python3的encode()和decode() 在python3的内存中. 在程序运行阶段. 使⽤用的是unicode编码. 因为unicode是万国码. 什么内容都可以进行显示. 那么在数据传输和存储的时候由于unicode比较浪费空间和资源. 需要把unicode转存成UTF-8或者GBK进行存储. 怎么转换呢. 在python中可以把⽂字信息进行编码. 编码之后的内容就可以进行传输了了. 编码之后的数据是bytes类型的数据.其实啊.还是原来的数据只是经过编码之后表现形式发生了改变而已…
