首先必須要導(dǎo)入 bs4 庫

　　from bs4 import BeautifulSoup

　　我們創(chuàng)建一個(gè)字符串，后面的例子我們便會(huì)用它來演示

　　html = """

　　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.

　　...

　　"""

　　創(chuàng)建 beautifulsoup 對(duì)象

　　soup = BeautifulSoup(html)

　　另外，我們還可以用本地 HTML 文件來創(chuàng)建對(duì)象，例如

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

　　上面這句代碼便是將本地 index.html 文件打開，用它來創(chuàng)建 soup 對(duì)象 下面我們來打印一下 soup 對(duì)象的內(nèi)容，格式化輸出

　　print soup.prettify()

　　輸出結(jié)果：

　　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.
