Python 美丽的汤查找\u所有人都无法获取特定链接的任何内容

所以我正在尝试这段代码，但我不知道为什么它没有输出任何东西：

import requests
import json
from bs4 import BeautifulSoup
s=requests.get("https://www.google.co.in/search?rlz=1C1CHBD_enIN789IN790&ei=iWj5WouoDsfGvgSr16bwDg&q=United+States%09KEEP+SMILIN+FAMILY+DENTAL%092281+N+ZARAGOZA+RD+STE+102&oq=United+States%09KEEP+SMILIN+FAMILY+DENTAL%092281+N+ZARAGOZA+RD+STE+102&gs_l=psy-ab.12...1153407.1153407.0.1154512.0.0.0.0.0.0.0.0..0.0....0...1c.1.64.psy-ab..0.0.0....0.YvWjU-kIBUs")
soup =BeautifulSoup(s.content,'html.parser')

#zloOqf, kpS1Ac, vk_gy : Tried all of these tags one by one but none worked
soup.find_all("div",{"class":"kpS1Ac"})

Out [30] : []

即使这样也不行：

soup.findAll("span",{"class":'YhemCb'})
Out [30] : []

所需输出：

Dental clinic in El Paso, Texas

您得到空结果的原因是您的response.content中缺少该结果。要获取此部分，请尝试向requests.get添加标题

HEADERS = {
           "User-Agent": "Mozilla/5.0(Macintosh; Intel Mac OS X 10_12_3) AppleWebKit/537.36(KHTML, like Gecko) Chrome/60.0.3112.101 Safari/537.36",
           "Accept-Language": "en-US,en;q=0.8,he;q=0.6",
          }
s = requests.get(<your_url>, headers=HEADERS)
soup =BeautifulSoup(s.content,'html.parser')
soup.findAll("span",{"class":'YhemCb'})

输出：

[<span class="YhemCb">Dental clinic in El Paso, Texas</span>]

您需要在请求中添加头并调用正确的类，即；zloOqf kpS1Ac vk_gy在BeautifulSoup模块中：

输出：

你的帖子中有两个限定答案，但你仍然不想发表任何评论或接受其中任何一个@vinita。有什么具体的原因吗？
