我正在尝试获取雅虎财务上给定报价的可用期权到期日列表。例如，在https://finance.yahoo.com/quote/SPY/options
上使用SPY作为代码过期列表在下拉列表中：
<div class="Fl(start) Pend(18px) option-contract-control drop-down-selector" data-reactid="4">
<select class="Fz(s)" data-reactid="5">
<option selected="" value="1576627200" data-reactid="6">December 18, 2019</option>
<option value="1576800000" data-reactid="7">December 20, 2019</option>
<option value="1577059200" data-reactid="8">December 23, 2019</option>
...
< / select >
< / div >
使用div类名（或选择类名，但是页面上似乎有几个这样的类，我将值列表作为连接的expiries的单个字符串获得。
我的功能（我从主要功能传递代码= SPY）：
def get_list_expiries(ticker):
browser = webdriver.Chrome()
options_url = "https://finance.yahoo.com/quote/" + str(ticker) + "/options"
browser.get(options_url)
html_source = browser.page_source
soup = BeautifulSoup(html_source, 'html.parser')
expiries_dt = []
for exp in soup.find_all(class_="Fl(start) Pend(18px) option-contract-control drop-down-selector"):
expiries_dt.append(exp.text)
browser.quit()
return expiries_dt
这产生了：
['December 18, 2019December 20, 2019December 23, 2019December 24, 2019December 27, 2019December 30, 2019...']
我知道我需要为此使用硒，但我不知道如何使用。结果始终是单个字符串的列表。理想情况下，我想返回两个列表：一个带有unix datetamp（选项value =“ 1576627200”），另一个带有“正常”日期的列表（即18/12/2019）。
任何帮助将不胜感激。
要提取unix datetamp和Expiry Dates，您必须引出WebDriverWait，并且可以使用以下Locator Strategies：
代码块：
from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.support.ui import Select
options = webdriver.ChromeOptions()
options.add_argument("start-maximized")
options.add_experimental_option("excludeSwitches", ["enable-automation"])
options.add_experimental_option('useAutomationExtension', False)
driver = webdriver.Chrome(options=options, executable_path=r'C:\WebDrivers\chromedriver.exe')
driver.get('https://finance.yahoo.com/quote/SPY/options')
select = Select(WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "div.option-contract-control.drop-down-selector>select"))))
print("Unix datestamp: ")
print([option.get_attribute("value") for option in select.options])
print("Dates: ")
print([option.get_attribute("innerHTML") for option in select.options])
控制台输出：
Unix datestamp:
