Mac OS X 10.9 Python 2.7 IDLE BeautifulSoup 4安装（成功）
我关注BS4 documentation并正在练习IDLE 上的一些功能。以下代码有效，并且可以打印出标题＆amp; title.name。
from bs4 import BeautifulSoup
html = """
<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)
print soup.title
print soup.title.name
打印结果：
<title>The Dormouse's story</title>
title
但是当我继续前进并尝试在下一行打印soup.title.string时：
print soup.title.string
它返回了：
Traceback (most recent call last):
File "/Users/yumiyang/Documents/python-folder/bsoup_test.py", line 24, in <module>
print soup.title.string
File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/idlelib/PyShell.py", line 1344, in write
s = unicode.__getslice__(s, None, None)
TypeError: an integer is required
然后，我尝试在终端上运行相同的代码：
Python [filename] .py
有效！
<title>The Dormouse's story</title>
title
The Dormouse's story
有人可以解释为什么代码在IDLE上没有工作但终端？谢谢！
答案 0 :(得分：0)
这是一个已知错误，在Python问题跟踪器上报告为issue #23583: IDLE: printing unicode subclasses broken (again)。
这是几个月前修复的，所以从版本2.7.10开始，这应该不再发生了。尝试更新你的Python！
