调用类和函数时 Python Selenium 中 xpath 中的变量

Question

我有以下课程：

class Sections(BasePage):

    CHOOSE_SECTION_SEL = (By.XPATH, "//*[@class='select2-result-label' and (text() = '" + state + "')]")

    def choose_section(self, state):
        self.click_on_element("choose section", self.CHOOSE_SECTION_SEL)

然后我想这样称呼它，这样我就可以随心所欲地更改变量“状态”，但它显然不起作用：

section = Sections(driver=self.driver)
section.choose_section(state="CALENDAR")

我知道我可以这样做并且它正在工作：

class Sections:

    def section(self, state):
        driver.find_element_by_xpath("//*[@class='select2-result-label' and (text() = '" + state + "')]").click()

...

choose = Sections()
choose.section(state="CALENDAR")

但是我必须像第一个例子那样做。 有什么想法我必须改变吗？

您可以将xpath表示法更改为以下任一形式：

• 使用变量：

   CHOOSE_SECTION_SEL = (By.XPATH, "//*[@class='select2-result-label' and text()='" + state + "']")

• 使用%s

   CHOOSE_SECTION_SEL = (By.XPATH, "//*[@class='select2-result-label' and text()='%s']"% str(state))

• 使用{}

   CHOOSE_SECTION_SEL = (By.XPATH, "//*[@class='select2-result-label' and text()='{}']".format(str(state)))

你可以像这样实现它：

class Sections(BasePage):

    def choose_section(self, state):
        self.CHOOSE_SECTION_SEL = (By.XPATH, "//*[@class='select2-result-label' and (text() = '" + state + "')]")
        self.click_on_element("choose section", self.CHOOSE_SECTION_SEL)
