import datetime.datetime as dt为什么报错？

Question

我是想把import datetime.datetime 作为一个类来使用的，报错了。请指导，谢谢

import datetime.datetime as dt
today_date=dt.now()
print(today_date)

错误：Traceback (most recent call last):
File "E:/pythontest/report_mail.py", line 2, in <module>
ModuleNotFoundError: No module named 'datetime.datetime'; 'datetime' is not a package

import datetime
today_date=datetime.datetime.now()
print(today_date)
