Python解码和编码

decode是解码，encode时编码

在Python2中默认时ASCLL，在Python3中默认时Unicode

gbk转向utf-8：先将gbk解码成Unicode，在编码成utf-8。

utf-8转向gbk：先将utf-8解码成Unicode，在编码成gbk。

Python2代码：

#-*- coding:utf-8 -*-

'''
@auther: Starry
@file: py2ende.py 
@time: 18-1-12 下午9:52 
'''

'''
Python2中默认是ASCII
'''
import sys

print(sys.getdefaultencoding())

s = '你好'

s_unicode = s.decode('utf-8')
s_gbk = s_unicode.encode('gbk')

print(s_unicode)
print(s_gbk)

gbk_to_utf8 = s_gbk.decode('gbk').encode('utf-8')
print(gbk_to_utf8)

Python3代码：

#!/usr/bin python3.5
#-*- coding:utf-8 -*-

print(s)


s_utf8 = s.encode('utf-8')
s_gbk = s.encode('gbk')

print(s_utf8)
print(s_gbk)

gbk_unicode = s_gbk.decode('gbk')
print(gbk_unicode)

utf8_to_gbk = s_utf8.decode('utf-8').encode('gbk')
gbk_to_utf8 = s_gbk.decode('gbk').encode('utf-8')

print(utf8_to_gbk)
print(gbk_to_utf8)
