创建 Beautiful Soup 对象

首先必须要导入 bs4 库

from bs4 import BeautifulSoup

我们创建一个字符串，后面的例子我们便会用它来演示

html = """
<html><head><title>The Dormouse's story</title></head>
<body>
<p class="title" name="dromouse"><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>
"""

创建 beautifulsoup 对象

soup = BeautifulSoup(html)

另外，我们还可以用本地 HTML 文件来创建对象，例如

soup = BeautifulSoup(open('index.html'))

上面这句代码便是将本地 index.html 文件打开，用它来创建 soup 对象

下面我们来打印一下 soup 对象的内容，格式化输出

print soup.prettify()

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

以上便是输出结果，格式化打印出了它的内容，这个函数经常用到，小伙伴们要记好咯。
