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 = """The Dormouse's story The Dormouse's story
Once upon a time there were three little sisters; and their names were , Lacie and Tillie; and they lived at the bottom of a well.
...
"""
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()
输出结果:
The Dormouse's story The Dormouse's story
Once upon a time there were three little sisters; and their names were , Lacie and Tillie ; and they lived at the bottom of a well.
