運(yùn)行如下Python打印語句：
print u'I "said" do not touch “this.""'
其中包含一個(gè)中文的雙引號(hào)，python解釋器報(bào)錯(cuò)。報(bào)錯(cuò)信息如下：

[wangy@bogon 文檔]$ python ex1.py
  File "ex1.py", line 7
SyntaxError: Non-ASCII character '\xe2' in file ex1.py on line 7, but no encoding declared; see http://www.python.org/peps/pep-0263.html for details

主要內(nèi)容如下：

好者造成很大的困擾，必須使用“unicode-escape”編碼來表示Unicode literals。


解決的方法就是為了讓解釋器了解源代碼的編碼，必須對(duì)源碼文件的編碼進(jìn)行聲明。


定義編碼的方式：
Python will default to ASCII as standard encoding if no other encoding hints are given.

To define a source code encoding, a magic comment must be placed into the source 

files either as first or second line in the file, such as:


# coding=
or (using formats recognized by popular editors):


#!/usr/bin/python
# -*- coding: -*-
or:


#!/usr/bin/python
# vim: set fileencoding= :




最好使用第一種或者第二種。


文中特別提到在windows平臺(tái)下，增加Unicode BOM標(biāo)記在Unicode文件頭，因此不需要特別聲明文件編碼，同理也會(huì)在UTF-8文件頭增加UTF-8標(biāo)記，故亦不需要聲明。

如果源文件使用 both the UTF-8 BOM mark signature and a magic encoding comment, the only allowed encoding for the comment is 'utf-8'. Any other encoding will cause an 
error.


Examples
These are some examples to clarify the different styles for defining the source code encoding at the top of a Python source file:

With interpreter binary and using Emacs style file encoding comment:

#!/usr/bin/python
# -*- coding: latin-1 -*-
import os, sys
...


#!/usr/bin/python
# -*- coding: iso-8859-15 -*-
import os, sys
...

#!/usr/bin/python
# -*- coding: ascii -*-
import os, sys
...
Without interpreter line, using plain text:
# This Python file uses the following encoding: utf-8
import os, sys
...
Text editors might have different ways of defining the file's encoding, e.g.:
#!/usr/local/bin/python
# coding: latin-1
import os, sys
...
Without encoding comment, Python's parser will assume ASCII text:
#!/usr/local/bin/python
import os, sys
...
Encoding comments which don't work:
Missing "coding:" prefix:
#!/usr/local/bin/python
# latin-1
import os, sys
...
Encoding comment not on line 1 or 2:
#!/usr/local/bin/python
#
# -*- coding: latin-1 -*-
import os, sys
...
Unsupported encoding:
#!/usr/local/bin/python
# -*- coding: utf-42 -*-
import os, sys
...

修改源代碼，以UTF-8保存，編輯器使用了Linux下的gedit
# -*- coding: utf-8 -*-
print "hello world!"
print "hello Again"
print "I like trying this"
print "This is fun"
print 'Yay! Printing'
print "I'd much rather you 'not'."
print u'I "said" 這里有中文雙引號(hào) “this.""'

正常打印
