当我输入简单代码时:

import datetime
datetime.utcnow()

,我收到错误信息:

Traceback (most recent call last):
  File "<pyshell#1>", line 1, in <module>
    datetime.utcnow()
AttributeError: 'module' object has no attribute 'utcnow'

但是python的文档utcnow就在这里:https://docs.python.org/library/datetime.html#datetime.datetime.utcnow.为什么utcnow我的电脑无法正常工作？谢谢!
