This means that the driver would check the readiness of a target element at a 2-second interval. The polling begins again if the previous attempt fails. The wait ends once the target element is available, allowing other testing activities. Python has a polling2 module that is used to wait ...

Python asyncio.wait_for用法及代码示例 用法: coroutine asyncio.wait_for(aw, timeout) 等待awawaitable 以超时完成。 如果aw是协程,它会自动安排为任务。 timeout可以是None或浮点数或 int 等待的秒数。如果timeout是None,则阻塞直到未来完成。 如果发生超时,它会取消任务并引发asyncio.TimeoutError。
1.until里面有个lambda函数,这个语法看python文档吧 2.以百度输入框为例 三、元素消失:until_not() 1.判断元素是否消失,是返回Ture,否返回False 备注:此方法未调好,暂时放这 四、参考代码: # coding:utf-8 from selenium import webdriver from selenium.webdriver.support.wait import WebDriverWait ...
