接受 1 个位置参数，但使用 Selenium Python 给了 2 个错误

Question

您好，我试图点击网站上的男性按钮：https://fs2.formsite.com/meherpavan/form2/index.html?1537702596407 但它给了我错误：

TypeError: element_to_be_clickable() takes 1 positional argument but 2 were given.

代码是

from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC


driver=webdriver.Chrome(executable_path="D:\ChromeDriverExtracted\chromedriver")
driver.get("https://fs2.formsite.com/meherpavan/form2/index.html?1537702596407")

WebDriverWait(driver, 2).until(EC.element_to_be_clickable(By.XPATH, "//type[@name='RESULT_RadioButton-7_0']")).click()

Answer 1

这是一个你应该传递的元组，

EC.element_to_be_clickable((By.XPATH, "//type[@name='RESULT_RadioButton-7_0']")))

Answer 2

您需要在element_to_be_clickable() 中传递一个元组，如下所示：

EC.element_to_be_clickable((By.XPATH, "//type[@name='RESULT_RadioButton-7_0']"))

但是，您的工作代码行将是：

WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//label[@for='RESULT_RadioButton-7_0']"))).click()

浏览器快照：

此外，selenium4 以下行：

webdriver.Chrome(executable_path="D:\ChromeDriverExtracted\chromedriver") 

现在与DeprecationWarning 关联如下：

DeprecationWarning: executable_path has been deprecated, please pass in a Service object

所以你需要传递一个 Service 类的实例作为参数，你的有效代码块将是：

from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC

s = Service('D:\ChromeDriverExtracted\chromedriver.exe')
driver = webdriver.Chrome(service=s)
driver.get("https://fs2.formsite.com/meherpavan/form2/index.html?1537702596407")
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//label[@for='RESULT_RadioButton-7_0']"))).click()
