__init__() 接受 2 个位置参数，但使用 WebDriverWait 和 expected_conditions 给出了 3 个作为 element_to_be_clickable 和 Selenium Python [英] __init__() takes 2 positional arguments but 3 were given using WebDriverWait and expected_conditions as element_to_be_clickable with Selenium Python

问题描述

我看到了类似的问题，但就我而言，我的代码中甚至没有init"函数.如何解决这个问题呢?问题在于 (EC.element_to_bo_clickable)

I saw similar questions but in my case there is not even "init" function in my code. How to solve this problem? The problem is with line (EC.element_to_bo_clickable)

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

driver = webdriver.Chrome(executable_path="C:Chromedriverchromedriver.exe")
driver.implicitly_wait(1)
driver.get("https://cct-103.firebaseapp.com/")

element = WebDriverWait(driver, 1).until
(EC.element_to_be_clickable(By.CLASS_NAME, "MuiButton-label"))

element.click()

推荐答案

根据定义，element_to_be_clickable() 应该在 tuple 中调用，因为它不是 函数 而是一个 class，其中初始化器只期望 implicit self 之外的 1 参数:

According to the definition, element_to_be_clickable() should be called within a tuple as it is not a function but a class, where the initializer expects just 1 argument beyond the implicit self:

class element_to_be_clickable(object):
    """ An Expectation for checking an element is visible and enabled such that you can click it."""
    def __init__(self, locator):
        self.locator = locator

    def __call__(self, driver):
        element = visibility_of_element_located(self.locator)(driver)
        if element and element.is_enabled():
            return element
        else:
            return False

所以而不是:

element = WebDriverWait(driver, 1).until(EC.element_to_be_clickable(By.CLASS_NAME, "MuiButton-label"))

您需要(添加额外的括号):

You need to (add an extra parentheses):

element = WebDriverWait(driver, 1).until((EC.element_to_be_clickable(By.CLASS_NAME, "MuiButton-label")))
