Python 键盘错误0开<；dl>；标签

我正在尝试解析HTML站点，但我有一个错误

代码如下：

from urllib.request import urlopen as uReq
from bs4 import BeautifulSoup as soup

my_url = "http://www.kontrakt.szczecin.pl/mieszkanie-sprzedaz-6664m2-339600pln-potulicka-nowe-miasto-szczecin-zachodniopomorskie,351165"

#PL: otwiera połączenie z wybraną stroną, pobieranie zawartości strony (urllib)
#EN: Opens a connection and grabs url

uClient = uReq(my_url)
page_html = uClient.read()
uClient.close()

#html parsing (BeautifulSoup)
page_soup = soup(page_html, "html.parser") #html.parser -> zapisujemy do html, nie np. do xml

#PL: zbiera tabelkę z numerami ofert, kuchnią i innymi danymi o nieruchomości z tabelki
#EN: grabs the data about real estate like kitchen, offer no, etc.
containers = page_soup.findAll("section",{"class":"clearfix"},{"id":"quick-summary"})

# print(len(containers)) - len(containers) sprawdza ile takich obiektów istnieje na stronie
#PL: Co prawda na stronie jest tylko jedna taka tabelka, ale dla dobra nauki zrobię tak jak gdyby tabelek było wiele.
#EN: There is only one table, but for the sake of knowledge I do the container variable
container = containers[0]
print(len(container.dl))
print(container.dl[0])

这是有错误的日志，显示

len（container.dl）显示dl中有36个。如果我使用len（container.dl.dt），它会显示：1.

您需要访问元素的内容，而不是通过直接索引，而是通过

。contents

属性：

print(container.dl.contents[0])

应该有用

通过直接索引，您可以访问标记的属性，例如，如果是

，则

dl['class']

将打印

myclass

编辑：

要打印容器.dl的所有内容，请执行以下操作：

from urllib.request import urlopen as uReq
from bs4 import BeautifulSoup as soup

my_url = "http://www.kontrakt.szczecin.pl/mieszkanie-sprzedaz-6664m2-339600pln-potulicka-nowe-miasto-szczecin-zachodniopomorskie,351165"

with uReq(my_url) as uClient:
    page_soup = soup(uClient.read(), "html.parser")

container = page_soup.findAll("section",{"class":"clearfix"},{"id":"quick-summary"})[0]

print(len(container.dl))
print('-' * 80)
for content in container.dl.contents:
    print(content)
    print('-' * 80)

打印（第一行是

container.dl.contents

的长度）：

有些事情发生了。我确实打印了（container.dl.dt.contents），但它只将列表中的第一个显示为['numeroferty']。我不知道为什么我看不到dt的其余部分。@bart我编辑了我的答案，我打印了所有

container.dl.contents

谢谢！我用另一种方式处理，但你的似乎更容易。顺便说一句，这是项目主题，我想请您检查一下：
