python打印中文异常

一、背景

脚本里需要打印中文内容。

二、脚本

'''
Created on Apr 27, 2016

@author: yeshaoting
'''

if __name__ == '__main__':
    print '你好，python!'

三、问题

python脚本里包含有中文时，报如下错误：

Traceback (most recent call last):
  File "/Applications/STS.app/Contents/Eclipse/plugins/org.python.pydev_4.5.5.201603221110/pysrc/pydevd.py", line 1529, in <module>
    globals = debugger.run(setup['file'], None, None, is_module)
  File "/Applications/STS.app/Contents/Eclipse/plugins/org.python.pydev_4.5.5.201603221110/pysrc/pydevd.py", line 936, in run
    pydev_imports.execfile(file, globals, locals)  # execute the script
  File "/Users/yeshaoting/java/workspace/python-workspace/HelloPython/base/HelloWorld.py", line 8
SyntaxError: Non-ASCII character '\xe4' in file /Users/yeshaoting/java/workspace/python-workspace/HelloPython/base/HelloWorld.py on line 8, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details

四、解决方法

告诉python解释器，按照utf-8编码读取源代码。

具体做法：在python脚本开头添加如下内容：

#coding=utf-8

或者：

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

注：此内容必须放在脚本shebang后一行(不允许隔空行)或者放在脚本第一行。

实例

#!/usr/bin/python
#coding=utf-8

print "你好，世界";
