比如浏览器驱动的Chrome_driver，声明他是WebDriver类，要使用WebDriver类，需导入其所属包

from selenium.webdriver.remote.webdriver import WebDriver
from selenium.webdriver.remote.webelement import WebElement
 
def __init__(self,Chrome_driver:WebDriver):
self.driver =Chrome_driver
 
def input(self,ele:WebElement,value):
ele.clear()
ele.send_keys(value)
