How do I change the datetime type to the datetime type?

Write datetime.datetime.date(). Returns the datetime.date object that stores the same year, month, and day as datetime.datetime.

Usually

mydatetime = datetime.datetime.now()
mydate = mydatetime.date()

#If you shorten it,
mydate = datetime.datetime.now().date()

However, if you only want to find out today's date, you can use the datetime object without it datetime.date.today() I don't mind just using it.
