How to replace the "-" sign?-CodePudding

I made a parser, you need it to compare ID dates every 30 minutes for parsing new content. But I can't use the "-" sign, what should I do?

The problem is date-time=True

import telebot
import requests
import time
from bs4 import BeautifulSoup

URL = "****"

page = requests.get(URL)
soup = BeautifulSoup(page.content, "html.parser")

post = soup.find("div", class_="largeTitle", date-time=True)
post_id = post["date=time"]

CodePudding user response：

Use the attributes argument to specify the attributes in a dictionary, rather than named arguments, when the attribute name isn't a valid Python name.

post = soup.find("div", attributes = {"class": "largeTitle", "date-time": True})

CodePudding user response：

You can use CSS selector as well "div.largeTitle[date-time]":

from bs4 import BeautifulSoup


html = """\
<div  date-time="xxx">This I want</div>
<div >This I don't</div>
"""

soup = BeautifulSoup(html, "html.parser")

post = soup.select_one("div.largeTitle[date-time]")
print(post)

Prints:

<div  date-time="xxx">This I want</div>

this looks minus operator, replace it with underscore _ or check this link:
