class TestCase(object): def __init__(self): self.driver = webdriver.Chrome() self.driver.get('http://www.baidu.com') self.driver.maximize_window() sleep(3) def test_id(self): element = self.driver.find_element(By.ID, 'kw').send_keys('yuanshen') sleep(3) self.driver.find_element(By.ID, 'su').click() sleep(10) self.driver.quit() if __name__ == '__main__': case = TestCase() case.test_id() 运行后为什么会打开两个百度窗口

python安装跟你一样的版本，为什么没有find-element-by-id 这个方法

老师，为什么我的编辑器不能自动联想呢，没有设置低电量，用的3.10的版本

老师我这边会一直校验图片的要怎么操作

from selenium import webdriver driver = webdriver.chrome() driver.maximize_window() 我的Pycharm环境 driver. 输入 m 没有自动提示出 maximize_window()这个方法

老师，你好！ 听完您第8课的讲解之后，我对最后一个知识点还有一点不太理解的地方。我不太清楚重新定义一个方法get_element(driver, *loc)有什么好处？ from selenium import webdriver from selenium.webdriver.common.by import By def get_element(driver, *loc): e = driver.find_element(*loc) return e if __name__ == '__main__': driver = webdriver.Chrome() driver.get('http://baidu.com') loc = (By.ID, 'kw') loc2 = (By.ID, 'su') get_element(driver, *loc).send_keys('selenium') get_element(driver, *loc2).click() 如果不额外定义一个方法，我在if __name__ == '__main__':代码里，直接使用driver.find_element(By.ID, 'kw').send_keys('selenium')的话，感觉代码会更少些。 from selenium import webdriver from selenium.webdriver.common.by import By if __name__ == '__main__': driver = webdriver.Chrome() driver.get('http://baidu.com') driver.find_element(By.ID, 'kw').send_keys('selenium') driver.find_element(By.ID, 'su').click() 老师能帮忙解答一下吗？谢谢！

老师，我元素定位时候报错。不知道是啥错误，能帮我看看嘛 element = self.driver.find_element_by_id('kw') AttributeError: 'TestCase' object has no attribute 'driver'

老师，使用linktext元素定位之后就反复出现下面这个错误： ConnectionRefusedError: [WinError 10061] 由于目标计算机积极拒绝，无法连接。

def get_element(driver, *loc): e = driver.find_element(*loc) return e 想问下自己定义一个类， driver.find_element中为什么不用加value就能够执行，value不是必填的参数吗
