代码如下：
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.common.action_chains import ActionChains
import time
options = webdriver.ChromeOptions()
prefs = {
'profile.managed_default_content_settings.images': 2
}
options.add_experimental_option('excludeSwitches', ['enable-logging'])
options.add_experimental_option('prefs',prefs)
driver = webdriver.Chrome(options= options)
driver.maximize_window()
driver.get('https://www.runoob.com/try/try.php?filename=tryjsref_radio_checked')
time.sleep(5)
iframe=driver.find_elements(by=By.CSS_SELECTOR,value="#iframeResult")
if len(iframe)>0:
driver.switch_to.frame('iframeResult')
for i in range(3):
elesBtnBuy = driver.find_elements(by=By.CSS_SELECTOR, value='input')
if len(elesBtnBuy) >0 :
elesBtnBuy[i].click()
print('click::',i)
print('radio count', len(elesBtnBuy) )
time.sleep(1)
else:
print('没有找到 iframe ')
