【问题描述】：
我是新手，正在尝试使用 python 和 selenium 创建一个机器人项目。 在我的机器人的这一部分中，我正在尝试创建一个 for 循环，以便程序刷新页面几次（使用搜索和后退按钮），然后继续执行我已排除的 while 循环的其余部分与我遇到的错误无关。
所以，我想做的是找到一个可以预订的位置。如果找到了一个插槽，我们就废弃了后退按钮，网页中将不再有这样的元素。所以，我利用这个功能摆脱了刷新循环，而是转到了 except 块，这有望让我摆脱两个循环（for 循环和 while 循环）。但是，我认为我仍然无法退出 for 循环，因为我看到此错误弹出，即使我已尝试处理 NoSuchElementException 错误。
no_slot = True
while no_slot == 1:
for i in range(60):
search_button = browser.find_element(By.NAME, "btnSearch")
search_button.click()
try:
noslot_back_button = browser.find_element(By.CSS_SELECTOR, 'input[name="btnBack"]')
except NoSuchElementException:
no_slot = False
break
else:
noslot_back_button.click()
这是我收到的错误：

请记住，Chrome 是在一个完全独立的进程中运行的。它不是 Python 的一部分。当它得到一个异常时，它会做自己的异常处理。
-
selenium.common.exceptions.ElementClickInterceptedException 似乎还有一个重叠元素：消息：元素点击拦截：元素 在点 (118, 330) 不可点击。其他元素会收到点击：
... 。您可以通过 driver.execute_script 单击元素来避免此错误。 -
嗨@ArundeepChohan，让我解释一下我对收到的错误的解释。那么在 try except 块由于后退按钮不再可点击而移动到 except 块期间，在 except 块中发生了另一个错误，导致这个重叠错误？另外，您能否详细说明 driver.execute_script 在我的情况下对我有什么帮助？谢谢
