打印utf-8编码的字符串。

I'm using BeautifulSoup to extract some text from an HTML but I just can't figure out how to print it properly to the screen (or to a file for that matter).

我正在用漂亮的汤从HTML中提取一些文本，但是我不知道如何正确地把它打印到屏幕上(或者是一个文件)。

Here's how my class containing the text looks like:

下面是我的类包含文本的方式:

class Thread(object):
    def __init__(self, title, author, date, content = u""):
        self.title = title
        self.author = author
        self.date = date
        self.content = content
        self.replies = []

    def __unicode__(self):
        s = u""

        for k, v in self.__dict__.items():
            s += u"%s = %s " % (k, v)

        return s

    def __repr__(self):
        return repr(unicode(self))

    __str__ = __repr__

When trying to print an instance of Thread here's what I see on the console:

在尝试打印线程实例时，我在控制台上看到:

~/python-tests $ python test.py
u'date = 21:01 03/02/11 content =  author = \u05d3"\u05e8 \u05d9\u05d5\u05e0\u05d9 \u05e1\u05d8\u05d0\u05e0\u05e6\'\u05e1\u05e7\u05d5 replies = [] title = \u05de\u05d1\u05e0\u05d4 \u05d4\u05de\u05d1\u05d7\u05df '

Whatever I try I cannot get the output I'd like (the above text should be Hebrew). My end goal is to serialize Thread to a file (using json or pickle) and be able to read it back.

无论我尝试什么，我都无法得到我想要的输出(上面的文本应该是希伯来语)。我的最终目标是将线程序列化到一个文件(使用json或pickle)，并能够读取它。

I'm running this with Python 2.6.6 on Ubuntu 10.10.

2 个解决方案

#1

To output a Unicode string to a file (or the console) you need to choose a text encoding. In Python the default text encoding is ASCII, but to support Hebrew characters you need to use a different encoding, such as UTF-8:

要将Unicode字符串输出到文件(或控制台)，您需要选择一个文本编码。在Python中，默认的文本编码是ASCII，但是为了支持希伯来字符，您需要使用不同的编码，比如UTF-8:

s = unicode(your_object).encode('utf8')
f.write(s)

#2

A nice alternative to @mark's answer is to set the environment variable PYTHONIOENCODING=UTF-8.

@mark的一个不错的替代方案是设置环境变量PYTHONIOENCODING=UTF-8。

c.f. Writing unicode strings via sys.stdout in Python.

通过sys编写unicode字符串。在Python stdout。

#1

s = unicode(your_object).encode('utf8')
f.write(s)
