    这是一个创建于 570 天前的主题,其中的信息可能已经有所发展或是发生改变。

    代码如下

    from selenium import webdriver
    
    import time
    # 打开浏览器
    #driver = webdriver.Chrome()
    driver = webdriver.Firefox()
    #driver = webdriver.Edge()
    # 设置浏览器最大化
    driver.maximize_window()
    # 设置隐式等待
    driver.implicitly_wait(3)
    # 打开网页
    driver.get("http://www.baidu.com")
    

    出现的错误

    语法没有问题,应该是 Selenium 或者 Webdriver 版本问题,建议卸载重装
