  (正确的方法来定义Python源代码编码 6个答案)

Consider:

(考虑：)

$ cat bla.py 
u = unicode('d…')
s = u.encode('utf-8')
print s
$ python bla.py 
  File "bla.py", line 1
SyntaxError: Non-ASCII character 'xe2' in file bla.py on line 1, but no encoding declared; see http://www.python.org/peps/pep-0263.html for details

How can I declare UTF-8 strings in source code?

Answer 1

In the source header you can declare:

(在源标头中，您可以声明：)

#!/usr/bin/env python
# -*- coding: utf-8 -*-
....

It is described in the PEP 0263 :

(它在PEP 0263中描述：)

Then you can use UTF-8 in strings:

(然后你可以在字符串中使用UTF-8：)

#!/usr/bin/env python
# -*- coding: utf-8 -*-

u = 'idzie w?? w?sk? dró?k?'
uu = u.decode('utf8')
s = uu.encode('cp1250')
print(s)

This declaration is not needed in Python 3 as UTF-8 is the default source encoding (see PEP 3120 ).

(Python 3中不需要此声明，因为UTF-8是默认的源编码（请参阅PEP 3120 ）。)

In addition, it may be worth verifying that your text editor properly encodes your code in UTF-8.

(此外，可能值得验证您的文本编辑器是否正确编码了UTF-8中的代码。)

Otherwise, you may have invisible characters that are not interpreted as UTF-8.

(否则，您可能会有不可解释为UTF-8的不可见字符。)
