我试图解析一个天气网站来打印某个地方的天气.在我学习 Python 时，之前我使用了 urllib.request.urlopen(url).read() 并且它有效.现在，我将代码修改为 BeautifulSoup4 和 requests 模块.下面是我的代码:
I was trying to parse a weather website to print weather for a place. As I am learning Python, previously I used urllib.request.urlopen(url).read() and it worked. Now, I am modifying the code to BeautifulSoup4 and requests module. Below is my code:
from bs4 import *
import requests
url = "https://www.accuweather.com/en/in/dhenkanal/189844/weather-forecast/189844"
data = requests.get(url)
soup = BeautifulSoup(data.text, "html.parser")
print(soup.find('div', {'class': 'info'}))
但是每次我尝试运行代码时都会出现以下错误:
But each time I try to run the code it gives me following error:

这是什么错误以及如何纠正它?为什么它在 urllib 中有效，而在请求中无效?
What is this error and how to correct it? And why it worked in urllib, but not in requests?
我直接使用了您的代码，但遇到了同样的错误，然后我遵循了浏览器中发送请求的方式.如果预期的标头没有与它们用作后端处理的一部分的请求一起发送，则某些服务器不会响应.原来服务器正在寻找一个名为 user-agent 的标头，通常用于确定请求来自哪个客户端.现在，修改下面的代码就可以了！
I used your code straight up and I got the same error then I followed how the requests are sent in browser. Some servers don't respond if expected headers are not sent with request that they use as part of backend processing. Turns out the server was looking for a header called user-agent usually used to determine what client the request is from. Now, amended code below which works!
from bs4 import *
import requests
url = "https://www.accuweather.com/en/in/dhenkanal/189844/weather-forecast/189844"
headers = {'user-agent':'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/62.0.3202.94 Safari/537.36'}
data = requests.get(url, headers=headers)
soup = BeautifulSoup(data.text, "html.parser")
现在你可以玩你的汤了！实际上，您可以传递更多的标头，例如 accept、dnt、pragma、accept-language、cache-control 等.这些 http 标头的解释是另一个问题，下次再说.希望它有帮助:)
Now you can play with your soup!
You can in fact pass more headers like accept, dnt, pragma, accept-language, cache-control etc. Explanation of these http headers are for another question, another time. Hope it helps :)
