如何正确使用split和Beautifulsoup？

Question

from bs4 import BeautifulSoup as bs
import requests
import time
import re


r = requests.get("https://www.crummy.com/software/BeautifulSoup/bs4/doc/")
soup = bs(r.content, "html.parser")
qqrcoisa = soup.find("h1")
print(qqrcoisa)
lista = qqrcoisa.split(" ")
print(lista)

错误：文件“C:/Users/claud/Desktop/Nova-意面/scrapando.py”，第13行，在 lista=qqrcosa.split（“文件”） TypeError:“非类型”对象不可调用

Answer 1

为了避免抛出错误，可以运行以下操作：

from bs4 import BeautifulSoup as bs
import requests

r = requests.get("https://www.crummy.com/software/BeautifulSoup/bs4/doc/")
soup = bs(r.content, "html.parser")
qqrcoisa = soup.find("h1")
if qqrcoisa:
    print(f"Found this h1 element: {qqrcoisa.text}")
    lista = qqrcoisa.tetx.split(" ")
    print(f"Split h1 element: {lista}")
else:
    print("No h1 element found")

Answer 2

您可以通过传递text将bs4元素转换为文本

qqrcoisa = soup.find("h1").text

如果要在<h1>和</h1>之间保留整行，可以将bs4元素转换为字符串

qqrcoisa = str(soup.find("h1"))

Answer 3

将“文本”函数添加到查找函数：

qqrcoisa = soup.find("h1").text
