解决方法:

根据您的问题获取网站https://www.airdna.co/中第一个建议的价值,一旦您发送搜索相关字符序列,您需要引导webdriverwait以使所需元素可见/可点击您可以使用以下解决方案：

>代码块：

driver.get("https://www.airdna.co/")
webdriverwait(driver, 10).until(EC.presence_of_element_located((By.CSS_SELECTOR,"input.ui-autocomplete-input"))).send_keys("la roch")
print(webdriverwait(driver, 10).until(EC.element_to_be_clickable((By.CSS_SELECTOR,"ul.ui-menu.ui-widget.ui-widget-content.ui-autocomplete.ui-front>li>div"))).get_attribute("innerHTML"))

>控制台输出：

La Rochelle, FR

>浏览器快照：

如果您想点击可以使用的第一个自动建议：

driver.get("https://www.airdna.co/")
webdriverwait(driver, 10).until(EC.presence_of_element_located((By.CSS_SELECTOR,"input.ui-autocomplete-input"))).send_keys("la roch")
print(webdriverwait(driver, 10).until(EC.element_to_be_clickable((By.CSS_SELECTOR,"ul.ui-menu.ui-widget.ui-widget-content.ui-autocomplete.ui-front>li>div"))).get_attribute("innerHTML"))
