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

嘿家伙，我正在尝试为该网站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 更改为数字，则一切正常。但是一旦我放入变量 i 它就不起作用，非常感谢任何帮助！

【解决方案1】：

而不是这个：

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()

嘿，谢谢你的回答，但遗憾的是这个错误代码发生了：UnboundLocalError: local variable 'range' referenced before assignment
查看更新的代码 1，它在我的本地工作
range 用于for i in range(length):
嘿，谢谢你的回复，问题是我必须按下按钮（查看个人资料），这样我才能访问电话号码，而不仅仅是名字和姓氏。
不，您在帖子中没有提到这一点。还有你的代码长度是多少？
