英文:
Bs4 is returning "[]" how do I go about fixing this error?
问题
我正在尝试创建一个代码，用于识别用户输入的搜索结果是否返回空白页面，我通过识别屏幕上是否存在特定文本来实现这一目标。
import requests
from bs4 import BeautifulSoup
site = input("输入顶级域名的域名：")
textsearch = input("输入您要查找的文本：")
r = requests.get(f"https://www.google.com/search?q=site%3A.{site}+%22{textsearch}%22")
soup = BeautifulSoup(r.text, 'html.parser')
search = soup.find_all(text="Try different keywords")
print(search)
问题是，当我知道该网页返回零结果时，这段代码会返回"[]"，我该如何修复这个问题？
英文:
I am trying to make a code that identifies if they search the use has inputted returns a blank page or not and I am doing this by identifying if there is certain text on the screen
import requests
from bs4 import BeautifulSoup
site = input("Input the domain of the top level domain: ")
textsearch = input("Input what text you're looking for: ")
r = requests.get(f"https://www.google.com/search?q=site%3A.{site}+%22{textsearch}%22")
soup = BeautifulSoup(r.text, 'html.parser')
search = soup.find_all(text="Try different keywords")
print(search)
The problem is this code is returning "[]" when I know this web page returns zero results, how do I go about fixing this?

只要您需要检查该短语是否出现在任何位置，那么您不需要Beautiful Soup 4（bs4）。
只需执行if "尝试不同的关键词" in r.text: print("错误：无结果")。
英文:
if all you need to do is see if that phrase is present anywhere then you do not need bs4
just do if "Try different keywords" in r.text: print("ERROR no results")
