我想从http://www.dividend.com/dividend-stocks/的第3个表中获取数据。 这是代码,我需要一些帮助。
import requests
from bs4 import BeautifulSoup
url = "http://www.dividend.com/dividend-stocks/"
r = requests.get(url)
soup = BeautifulSoup(r.content, "html5lib")
# Skip first two tables
tables = soup.find("table")
tables = tables.find_next("table")
tables = tables.find_next("table")
row = ''
for td in tables.find_all("td"):
if len(td.text.strip()) > 0:
row = row + td.text.strip().replace('\n', ' ') +','
# Handle last column in a row, remove extra comma and add new line
if td.get('data-th') == 'Pay Date':
row = row[:-1] + '\n'
print(row)
但代码输出如下:
AAPL,Apple Inc.,1.76%,$143.39,$2.52,5/11,5/18
GE,General Electric,3.32%,$28.91,$0.96,6/15,7/25
XOM,Exxon Mobil,3.71%,$83.03,$3.08,5/10,6/9
CVX,Chevron Corp,4.01%,$107.72,$4.32,5/17,6/12
BP,BP PLC ADR,6.66%,$35.72,$2.38,5/10,6/23
我做错了什么?谢谢你的帮助!

您可以使用选择器查找特定的表格:
tables = soup.select("table:nth-of-type(3)")
我不确定为什么您的搜索结果的顺序与网页上显示的顺序不同。

尽管@Barmar的方法看起来更干净,但这是另一种使用soup.find_all
并保存到JSON的替代方法(即使说明中没有这样做)。
import json
import requests
from bs4 import BeautifulSoup
url = 'http://www.dividend.com/dividend-stocks/'
r = requests.get(url)
r.raise_for_status()
soup = BeautifulSoup(r.content, 'lxml')
stocks = {}
# Skip first two tables and header row of target table
for tr in soup.find_all('table')[2].find_all('tr')[1:]:
(stock_symbol, company_name, _, dividend_yield, current_price,
annual_dividend, ex_dividend_date, pay_date) = [
td.text.strip() for td in tr.find_all('td')]
stocks[stock_symbol] = {
'company_name': company_name,
'dividend_yield': float(dividend_yield.rstrip('%')),
'current_price': float(current_price.lstrip('$')),
'annual_dividend': float(annual_dividend.lstrip('$')),
'ex_dividend_date': ex_dividend_date,
'pay_date': pay_date
}
with open('stocks.json', 'w') as f:
json.dump(stocks, f, indent=2)

感谢@Barmar和@Delirious Lettuce发布解决方案和代码。 关于输出的顺序,我意识到每次刷新数据时,我都看到了输出顺序的数据,就像我拉出来的那样。然后我看到排序的数据。尝试了几种不同的方法,我能够使用Selenium webdriver来提取网络所呈现的数据。谢谢大家。
