Question

我想刮掉倾斜的绳子＆＃34;睡鼠的故事＆＃34;在HTML中，使用beautifulsoup工具。

#!/usr/bin/python
# -*- coding: utf-8 -*-
from bs4 import BeautifulSoup
html_doc = """
<html>

<head>
  <title>The Dormouse's story</title>
</head>

<body>
  <p class="title"><b>The Dormouse's story</b>
  </p>

  <p class="story">Once upon a time there were three little sisters; and their names were
    <a href="http://example.com/elsie" class="sister" id="link1">Elsie</a>,
    <a href="http://example.com/lacie" class="sister" id="link2">Lacie</a> and
    <a href="http://example.com/tillie" class="sister" id="link3">Tillie</a>; and they lived at the bottom of a well.</p>

  <p class="story">...</p>

  """ 
soup = BeautifulSoup(html_doc) 
print soup.title.string

我使用Python2.7.9 IDE，错误描述为

Traceback (most recent call last):
  File "C:/Python27/Scripts/test.py", line 23, in <module>
    print soup.title.string
  File "C:\Python27\lib\idlelib\PyShell.py", line 1353, in write
    s = unicode.__getslice__(s, None, None)
TypeError: an integer is required

如果我需要更改变量的类型，我该如何解决这个问题？

Answer 1

使用运行模块命令运行脚本时，这是IDLE中的错误;解决方法是在对象上使用unicode()：

print unicode(soup.title.string)

问题是由issue 19481的错误修复引起的;我怀疑unicode.__getslice__方法已被清除和/或从不支持使用None索引，至少在Python 2中。

我为此问题打开了new bug on IDLE。

Answer 2

我认为这是IDE中的一个错误，当我使用它时，没有错误。

 <<ret = urllib2.urlopen(url).read()
 <<soup = BeautifulSoup(ret)
 <<print soup.title.string

当我使用beautifulsoup在HTML中删除字符串时，为什么它们不起作用
