AttributeError: ‘method_descriptor‘ object has no attribute ‘today‘

错误：AttributeError: ‘method_descriptor’ object has no attribute ‘today’
出错代码：

yesterday = datetime.date.today() - datetime.timedelta(days=1)
yesterday_timestamp = int(time.mktime(yesterday.timetuple())) * 1000

导入原句：

from datatime import *

按提示改成：

import datetime

解决。
