方法三：结合WebDriverWait和expected_conditions判断
from selenium import webdriver
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.support.ui import WebDriverWait
def is_element_exsist2(driver, locator):
'''\r\n 结合WebDriverWait和expected_conditions判断元素是否存在,
每间隔1秒判断一次，30s超时，存在返回True,不存返回False
:param locator: locator为元组类型，如("id", "yoyo")
:return: bool值，True or False
'''
try:
WebDriverWait(driver, 30, 1).until(EC.presence_of_element_located(locator))
return True
except:
return False
if __name__ == '__main__':
loc1 = ("id", "yoyo") # 元素1
print(is_element_exsist2(driver, loc1))
