调用类和函数时，Python Selenium中的xpath中的变量 [英] Variable in xpath in Python Selenium when calling Class and Function

问题描述

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)

然后我要这样称呼它，以便我可以更改变量'state'到我想要的任何地方，但是它显然不起作用:

Then I want to call it like this so I can change the variable 'state' whatever I want but it is not working obviously:

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

我知道我可以这样做，并且可以正常工作:

I know I can do it like this and it is working:

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，我必须像第一个示例那样去做.有什么需要改变的想法吗?

However I have to do it like the first example. Any ideas what I have to change?

推荐答案

您可以更改 xpath 表示为以下两种形式之一:

You can change the xpath notation to either of the following forms:

• 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)))

您可以像这样实现它:

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)
