from selenium import webdriver

from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support import expected_conditions as EC
import os

Game_Pin = input('Enter your PIN: ')
NickNAME = input('Enter your nickname: ')
driver = webdriver.Chrome(executable_path=r"C:\WebDriver\bin\chromedriver.exe")

def Enter_Press(driver):
    driver.find_element_by_xpath("//*[contains(text(), 'Enter')]").click()

def OK_GO(driver):
    driver.find_element_by_xpath("//*[contains(text(), 'OK, go!')]").click()


def Kahoot_Spammer(Game_Pin, NickNAME, driver):
    driver.get('https://kahoot.it/')
    driver.maximize_window() #For maximizing window
    driver.implicitly_wait(2) #gives an implicit wait for 2 seconds

    game_pin = driver.find_element_by_xpath("//*[@id='inputSession']")
    game_pin.send_keys(Game_Pin)
    Enter_Press(driver)

    driver.implicitly_wait(2)
    Name = driver.find_element_by_xpath("//*[@id='username']")
    Name.send_keys(NickNAME)
    OK_GO(driver)




Kahoot_Spammer(Game_Pin, NickNAME, driver)

这就是代码。它应该打开chrome浏览器并导航到Kahoot.it网站。然后拿出你给它的信息，然后把它放进去。它适用于进入游戏的第一部分，但是一旦它创建了你的昵称，它就无法检测到OK，go！按钮。

driver.find_element_by_xpath("//*[contains(text(), 'OK, go!')]").click()

我已经检查了按钮，但似乎找不到要在上面的代码中放置什么。有什么想法吗？

这是源代码。

在初始化implicitly_wait时，只需将声明为一次。要显式等待指定的秒数，可以使用time.sleep()，尽管更实用的解决方案是使用Selenium的WebDriverWait动态等待元素出现/可单击。
