代码： 

# 3.2  定位节点
ele=driver.find_element_by_xpath('//ul[@class="m-cvrlst f-cb"]/li/p/a')

# 3.3 模拟点击
ele.click()

发生异常：

selenium.common.exceptions.ElementClickInterceptedException: Message: element click intercepted: Element <iframe name="contentFrame" id="g_iframe" class="g-iframe" scrolling="auto" frameborder="0" src="about:blank" allowfullscreen="true" cd_frame_id_="9df25c30d23c193344fae23a89222cdb"></iframe> is not clickable at point (109, 632). Other element would receive the click: <div class="btns">...</div>
  (Session info: chrome=90.0.4430.93)

原因：应该是元素定位相互覆盖。

解决：将单击修改成js

driver.execute_script("arguments[0].click();", ele)
