there 一點 tor 裏的 names col python attribute 就是
html=""" #註意，第一次寫，縮進了一點點，python對格式十分註重。。
<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/title" class="sister" id="link3">title</a>;
and they lived at the bottom of a well.</p>
<p class="story">...</p>"""
soup=BeautifulSoup(html,"lxml") #註意：括號裏的html沒有“”，第一次加了雙引號。。
print(soup.prettify()) #prettify()可以自己把html代碼格式調整好。
print(soup.title.string) #輸出title裏面的字符。。
出錯：就是因為soup=BeautifulSoup("html","lxml") html多加了“”
