英文:
I keep getting "None" in beautiful soup for every website that I try to scrape
问题
我只会翻译文本部分，不会翻译代码。以下是您提供的文本的翻译：
我只是尝试做一个简单的天气应用程序，我试图通过获取天气标签来抓取开放天气，但它一直报错
AttributeError: 'NoneType' object has no attribute 'span'
如果我删除 .span，它只会显示 None，这也不是我想要的。
我希望能够打印出 HTML 标签。我不确定出了什么问题，而且如果我删除 span，它也只会显示 none。
代码：
from bs4 import BeautifulSoup
import requests
import re
url = "https://openweathermap.org/city/4930956" # 从中获取天气的城市的 URL
page = requests.get(url).text # 使用 requests 获取页面内容
doc = BeautifulSoup(page,"html.parser") # 使用 BeautifulSoup 解析文档
temperature = doc.find(class_="heading") # 获取位于 heading 类中的温度值，该温度值位于 span 标签中
print(temperature) # 打印标签
英文:
I was just trying to do a simple weather app and I was trying the scrape open weather by getting the tag of the weather but it kept saying
AttributeError: 'NoneType' object has no attribute 'span'
If I remove the .span it just says None which is also not what I want.
I was expecting to get the html tag printed out. I'm not sure what's going wrong, also if I remove the span it just says none.
code:
from bs4 import BeautifulSoup
import requests
import re
url = "https://openweathermap.org/city/4930956" #url for the city that im getting the weeather from
page = requests.get(url).text #using requets
doc = BeautifulSoup(page,"html.parser") #reading the document with beautifulsoup
temperature = doc.find(class_="heading") #getting the temperature value which is in the heading class with the span tag
print(temperature) #printing the tag

这并不完全回答你的问题，但他们有一个API https://openweathermap.org/api
看起来这个API可以免费使用，每天少于一千次查询。
你可能会遇到一些防止爬取的问题，因为他们希望人们要么通过API访问他们的数据，要么像普通人一样浏览他们的网站。
由于我声望不够高，无法回答你的问题哈哈。

This doesn't answer your question exactly, but they have an api https://openweathermap.org/api
Looks like the api is free to use for less than a thousand queries per day.
You might be experiencing some anti-scraping stuff from them, as they want people to access their data either through the api or as a normal person looking at the website.
Can't reply to your question as I don't have enough rep lol
