Python character encoding

Python character encoding

1. The earliest character encoding standard: ASCII

   1. 127 characters, no Chinese

   2. 1 English letters required 1 bytes

8 bits = 1 bytes

1024 bytes =1kb

1024kb=1mb

Later, in order to extend Chinese support, there appeared GB2312, GBK later appeared Unicode

1. Unify all languages into one set of codes.
   

2. Each character occupies 2 bytes

   
   

Final UTF-8 (compression and optimization of Unicode)

1. 1 English 1 bytes

2. 1 Chinese 3 bytes
   

Python3. X default Unicode encoding, Chinese python2 is supported by default. X default ASCII encoding, unable to support Chinese

1. Support Chinese Way:

   #!/bin/bash/env python #解释器

   #_ *_ coding:utf-8 _*_ #加字符集
