强制等待

from time import sleep
sleep(5)

隐性等待

driver.implicitly_wait(10)

我们等待元素已经加载出来了，但页面还没有加载完，需要继续等待页面加载完才能执行下一步操作。

显性等待

from  selenium.webdriver.support.wait import WebDriverWait
from selenium.webdriver.support import expected_conditions as ECfrom selenium.webdriver.common.by import  By
wait = WebDriverWait(driver, 10, 0.5)wait.until(EC.presence_of_element_located((By.ID, 'KW')))
loc = ("xpath", "//*[@text='允许']")
e = WebDriverWait(driver, 1, 0.5).until(EC.presence_of_element_located(loc))e.click()
