Python 2.7 AttributeError："ResultSet"对象没有属性"replace"

Question

我正在使用BeautifulSoup和Urllib来制作Wikipedia Web刮板。我只是继续遇到同样令人讨厌的错误。

我的代码：

from bs4 import BeautifulSoup
import urllib
page = urllib.urlopen("https://en.wikipedia.org/wiki/Donald_Trump").read()
soup = BeautifulSoup(page, "html.parser")
nickname = soup.find_all("span", class_="nickname")
nickname.replace('[<span class="nickname">','')
nickname.replace('</span>]','')
print(nickname)

错误：

AttributeError: 'ResultSet' object has no attribute 'replace'

Answer 1

nickname具有datatype ResultSet，如果要对其进行一些字符串操作，则必须将其转换为字符串。

from bs4 import BeautifulSoup
import urllib
page = urllib.urlopen("https://en.wikipedia.org/wiki/Donald_Trump").read()
soup = BeautifulSoup(page, "html.parser")
nickname = soup.find_all("span", class_="nickname")
nicknameStr = str(nickname)
nicknameStr.replace('[<span class="nickname">','')
nicknameStr.replace('</span>]','')
print(nicknameStr)
