显式等待有什么举例吗?

from selenium import webdriver

from selenium.webdriver.common.byimport By

from selenium.webdriver.support.ui import WebDriverWait

from selenium.webdriver.support import expected_conditions as EC

browser=webdriver.Chrome()

browser.get('https://www.taobao.com/') 

wait=WebDriverWait(browser10)

input =wait.until(EC.presence_bf_element_located((ByID'q)))

button=wait.until(EC.elementto_be_clickablel((ByCSSSELECTOR.'btn-search'))) 

print(input, button)
