我在运行代码一直提示定位有问题，我是不是try和except用法不对啊

Question

   try:
        element = None
        if by == "id":
            element = self.driver.find_element_by_id(value)
        elif by == "name":
            element = self.driver.find_element_by_name(value)
        elif by == "css":
            element = self.driver.find_element_by_css(value)
        elif by == "class":
            element = self.driver.find_element_by_class(value)
        elif by == "xpath":
            element = self.driver.find_element_by_xpath(value)
    except:
        print("定位by和value有问题")
    return element
    
    #运行代码
request_driver = SeleniumDriver()
request_driver.get_url("https://www.imooc.com/user/newlogin")
request_driver.get_element("name","email")

你需要告诉我你报得是什么错误。这个需要放try外面。except 这个后面你可以把你exception异常跑出来看看

  我把try和except注释到了然后他报了这个错str' object has no attribute 'find_element_by_name'

  你str没有查找对象，你driver不对。
