Tips for sharing Python Chinese Characters

There are many useful operations in the Python programming language that can help us easily implement functions in certain environments. For example, you can operate on Chinese characters. Today, let's take a look at the application skills related to Chinese Characters in Python.

Python-related operation code example:

 
 

  
  
#! /Usr/bin/python
  
  
#-*-Coding: UTF-8 -*-
  
  
S = "China"
  
  
Ss = u "China"
  
  
Print s, type (s), len (s)
  
  
Print ss, type (ss), len (ss)
  
  
Print '-' * 40
  
  
Print repr (s)
  
  
Print repr (ss)
  
  
Print '-' * 40
  
  
Ss1 = s. decode ('utf-8 ')
  
  
Print s1, len (s1), type (s1)
  
  
Print '-' * 40
  
  
Ss2 = s. decode ('utf-8'). encode ('gbk ')
  
  
Print s2
  
  
Print type (s2)
  
  
Print len (s2)
  
  
Print '-' * 40
  
  
S3 = ss. encode ('gbk ')
  
  
Print s3
  
  
Print type (s3)
  
  
Print len (s3)
 
 

The execution result is as follows:

 
 

  
  
China <type 'str'> 6
  
  
China <type 'unicode '> 2
  
  
----------------------------------------
  
  
'\ Xe4 \ xb8 \ xad \ xe5 \ x9b \ xbd'
  
  
U' \ u4e2d \ u56fd'
  
  
----------------------------------------
  
  
China 2 <type 'unicode '>
  
  
----------------------------------------
  
  
��
  
  
<Type 'str'>
  
  
4
  
  
----------------------------------------
  
  
��
  
  
<Type 'str'>
  
  
4

View the default encoding settings for Chinese Characters in Python:

 
 

  
  
>>> import sys  
  
  
>>> sys.getdefaultencoding()  
  
  
'ascii' 
 
 

Because #-*-coding: UTF-8-*-is specified on the file header, the encoding of s is UTF-8.

In UTF-8, English letters are one byte, and Chinese characters are three bytes;

The Chinese Character in unicode is 1 character dubyte );

The Chinese Character in GBK encoding occupies 2 bytes. (Thanks to keakon for correcting)
