visibility_of_element_located方法找不到元素时，返回结果不是false

Question

试了一下visibility_of_element_located方法的返回结果跟您讲的有点区别，当找不到元素的时候，报了如下的错，而不是返回false
selenium.common.exceptions.ElementNotVisibleException: Message: element not visible

全部代码太长了就给您粘一部分吧

def operation(self,type,oper,location,sendkey):
   if(type=='xpath'):
       #WebDriverWait(self.driver, 12).until(EC.visibility_of_element_located((By.XPATH,location)))
       obj=By.XPATH,location
       print(EC.visibility_of_element_located(obj))

open_chrome.operation('xpath','click','/html/body/div/div[1]/div[2]/div/div[3]/div/ul/li[1]/ul/li[4]','')

如果找不到控件打印出来的结果就直接是报错信息了

selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {"method":"xpath","selector":"/html/body/div/div[1]/div[2]/div/div[3]/div/ul/li[1]/ul/li[4]"}

这个有问题，你把代码发一下，这个按照写法讲的一样你的结果不一样？

  亲，这里是需要封装呀。就是wait那个util那个。我们说的是这个和我们自己缝状一个local element
