如何在for循环中的xpath中插入变量？

Question

for i in range(length):
        # print(i)
        driver.execute_script("window.history.go(-1)")
        range = driver.find_element_by_xpath("(//a[@class = 'button'])[i]").click()


        content2 = driver.page_source.encode('utf-8').strip()
        soup2 = BeautifulSoup(content2,"html.parser")
        name2 = soup2.find('h1', {'data-qa-target': 'ProviderDisplayName'}).text
        phone2 = soup2.find('a', {'class': 'click-to-call-button-secondary hg-track mobile-click-to-call'}).text
        print(name2, phone2)

嘿，伙计，我正在努力为这个网站上的每个人刮取名字和姓氏、电话：https://www.healthgrades.com/family-marriage-counseling-directory。我希望（l.4）按钮适应变量（I）。如果我手动将i改为一个数字，一切都会正常工作。但是，一旦我把它放在变量中，它就不起作用了，非常感谢任何帮助

与此相反：

range = driver.find_element_by_xpath("(//a[@class = 'button'])[i]").click()

这样做：

range = driver.find_element_by_xpath(f"(//a[@class = 'button'])[{i}]").click()

更新1:

driver = webdriver.Chrome(driver_path)
driver.maximize_window()
driver.implicitly_wait(50)
driver.get("https://www.healthgrades.com/family-marriage-counseling-directory")

for name in driver.find_elements(By.CSS_SELECTOR, "a[data-qa-target='provider-details-provider-name']"):
  print(name.text)

leng = len(driver.find_elements(By.CSS_SELECTOR, "a[data-qa-target='provider-details-provider-name']"))
for i in range(leng):
  driver.find_element_by_xpath(f"(//a[text()='View Profile'])[{i}]").click()
