尝试检索嵌入在html中的内容（文本）。没有得到内容。
尝试使用格式为select_box的选择器：price_box = soup2.find('div', attrs={'title class': 'Fw(600)'})
# Import libraries
import requests
import urllib.request
import time
from bs4 import BeautifulSoup
# Set the URL you want to webscrape from
url = 'https://finance.yahoo.com/quote/NVDA?p=NVDA'
# Connect to the URL
response = requests.get(url)
# Parse HTML and save to BeautifulSoup object¶
soup = BeautifulSoup(response.text, "html.parser")
beta = soup.find('h1')
#print (beta)
link = beta.contents
variable = 'NVDA - NVIDIA Corporation'
test = 'NVDA - NVIDIA Corporation'
#<..>
url2 = 'https://finance.yahoo.com/calendar/earnings?from=2019-09-01&to=2019-09-07&day=2019-09-01'
response2 = requests.get(url2)
soup2 = BeautifulSoup(response2.text, "html.parser")
# alpha = soup2.find('')
# div = soup.find('a', {class_ ='D(ib) '})
# text = div.string
price_box = soup2.find('div', attrs={'title class': 'Fw(600)'})
#price = price_box.text
print("Price Box: "+ str(price_box)) # THIS IS WHAT I WANT
希望看到“ Senea”。而是看到“无”-“价格框：
没有”
最佳答案
许多内容是动态的。您可以轻松地将信息正则表达式
import requests, re
p = re.compile(r'"YFINANCE:(.*?)"')
r = requests.get('https://finance.yahoo.com/calendar/earnings?from=2019-09-01&to=2019-09-07&day=2019-09-01&guccounter=1')
print(p.findall(r.text)[0])
另一种方法是完全避免使用动态外观的类
import requests
from bs4 import BeautifulSoup as bs
r = requests.get('https://finance.yahoo.com/calendar/earnings?from=2019-09-01&to=2019-09-07&day=2019-09-01&guccounter=1')
soup = bs(r.content, 'lxml')
print(soup.select_one('#cal-res-table a').text)
