Python selenium PO  By.XPATH定位元素报错

如下代码经常报错：

    # 首页的“新建投放计划”按钮
    new_ads_plan = (By.XPATH, "//*[text()=‘百度新闻‘]/..")


    print(type(self.new_ads_plan))
    self.driver.find_element(self.new_ads_plan).click()

运行经常报错：
selenium.common.exceptions.WebDriverException: Message: invalid argument: ‘using‘ must be a string

 

解决办法：

self.driver.find_element(*self.new_ads_plan).click()

在参数里面的元素定位 self 前加一个星号 *

    new_ads_plan = (By.XPATH, "//*[text()=‘百度新闻‘]")
    shouye = (By.XPATH, "//a[text()= ‘首页‘]")
    zanTing = (By.XPATH, "//span[text()= ‘删 除‘]")
    bianji = (By.XPATH, "//span[text()= ‘编 辑‘]")
    addSuCai = (By.XPATH, "//span[text()= ‘添加‘]")


    def isElementExists(self, *loc):
        flag = True
        try:
            for num in range(0, len(loc)):
                print(str(loc[num]))
                self.driver.find_element(*loc[num])
            return flag
        except:
            flag = False
            return flag



    # 判断元素是否显示
    def is_ElementExists(self):
        return self.isElementExists((self.new_ads_plan), 
                                    (self.shouye),
                                    (self.zanTing),
                                    (self.bianji),
                                    (self.addSuCai))   
 
       # 此处必须将多个定位元素的入参以元祖的形式填入，每一个元素的定位参数都是一个数组。
