美丽的汤统一code EN code错误 [英] Beautiful Soup Unicode encode error

问题描述

我想下面的code与特定的HTML文件

I am trying the following code with a particular HTML file

from BeautifulSoup import BeautifulSoup
import re
import codecs
import sys
f = open('test1.html')
html = f.read()
soup = BeautifulSoup(html)
body = soup.body.contents
para = soup.findAll('p')
print str(para).encode('utf-8')

我收到以下错误：

I get the following error:

UnicodeEncodeError: 'ascii' codec can't encode character u'\u2019' in position 9: ordinal not in range(128)

如何调试呢？

当我删除调用打印功能我没有得到任何错误。

I do not get any error when I remove the call to print function.

推荐答案

STR（段） 内置尝试使用默认值（ ASCII ）编码的UNI code在对。
这是的连接code（）调用之前完成的

The str(para) builtin is trying to use the default (ascii) encoding for the unicode in para. This is done before the encode() call:

>>> s=u'123\u2019'
>>> str(s)
Traceback (most recent call last):
  File "<interactive input>", line 1, in <module>
UnicodeEncodeError: 'ascii' codec can't encode character u'\u2019' in position 3: ordinal not in range(128)
>>> s.encode("utf-8")
'123\xe2\x80\x99'
>>> 

尝试编码对直接，也许通过应用连接code（UTF-8）来每个列表元素。

Try encoding para directly, maybe by applying encode("utf-8") to each list element.
