python中文编码问题

第一步:在代码中输入以下命令,执行:

#在Python中显示中文注释和输出中文
a ="中文"
print a

返回错误:

d:Python27python.exe "D: est中文.py"
Process started >>>
  File "D: est中文.py", line 1
SyntaxError: Non-ASCII character 'xe5' in file D: est中文.py on line 1, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details
<<< Process finished. (Exit code 1)
================ READY ================

第二步,加入编码格式:

#-*- coding:utf-8 –*-

#在Python中显示中文注释和输出中文
a ="中文"
print a

返回结果:

d:Python27python.exe "D: est中文.py"
Process started >>>
涓�枃
<<< Process finished. (Exit code 0)
================ READY ================

程序可以正确执行,但输出的仍是乱码。

第三步,查找乱码并处理:

原因:这是因为win的,命令行用的是cp936编码,而上面脚本用的是utf-8编码,因此导致乱码。

解决方法是,使用decode和encode函数对字符重新解码和编码。

#-*- coding:utf-8 –*-
#在Python中显示中文注释和输出中文

#import sys
#reload(sys)
#sys.setdefaultencoding('utf-8')

a ="中文"
print a.decode('utf-8').encode('cp936') 

返回结果:

d:Python27python.exe "D: est中文.py"
Process started >>>
中文
<<< Process finished. (Exit code 0)
================ READY ================
