Question

我正在尝试创建一个小的python脚本，但我不断收到错误代码：

 File "C:\Users\Eddie\AppData\Local\Programs\Python\Python35-32\selenium xpath testing.py", line 30, in <module>
    driver.find_element_by_xpath(".//*[@id='page-content']/section[1]/div[1]/nav/div/div[1]/a[1]/i[1]").click()
  File "C:\Users\Eddie\AppData\Local\Programs\Python\Python35-32\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 293, in find_element_by_xpath
    return self.find_element(by=By.XPATH, value=xpath)
  File "C:\Users\Eddie\AppData\Local\Programs\Python\Python35-32\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 752, in find_element
    'value': value})['value']
  File "C:\Users\Eddie\AppData\Local\Programs\Python\Python35-32\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 236, in execute
    self.error_handler.check_response(response)
  File "C:\Users\Eddie\AppData\Local\Programs\Python\Python35-32\lib\site-packages\selenium\webdriver\remote\errorhandler.py", line 192, in check_response
    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.NoSuchElementException: Message: Unable to locate element: {"method":"xpath","selector":".//*[@id='page-content']/section[1]/div[1]/nav/div/div[1]/a[1]/i[1]"}

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "C:\Users\Eddie\AppData\Local\Programs\Python\Python35-32\selenium xpath testing.py", line 37, in <module>
    except (ElementNotVisibleException or NoSuchElementException) or (ElementNotVisibleException and NoSuchElementException):
NameError: name 'ElementNotVisibleException' is not defined

这是我的代码

count=0
while count < 100:
    #this both works
    try:
        driver.find_element_by_xpath(".//*[@id='page-content']/section[1]/div[2]/div/section/div[2]/div/a[2]").click()
        driver.find_element_by_xpath(".//*[@id='page-content']/section[1]/div[1]/nav/div/div[1]/a[1]/i[1]").click()
        time.sleep(5)
        driver.back()
        time.sleep(5)
        driver.refresh()
        count +=1
        print(count)
    except (ElementNotVisibleException or NoSuchElementException) or (ElementNotVisibleException and NoSuchElementException):
        driver.back()
        time.sleep(5)
        driver.refresh()
        time.sleep(5)
        driver.find_element_by_xpath(".//*[@id='page-content']/section[1]/div[2]/div/section/div[2]/div/a[2]").click()
        time.sleep(5)
        driver.find_element_by_xpath(".//*[@id='page-content']/section[1]/div[1]/nav/div/div[1]/a[1]/i[1]").click()
        count +=1
        print(count)

为什么当我使用except处理它时，没有定义ElementNotVisible的任何想法？

当我只是将异常更改为异常时：

我还在
