8.4. Datetime Current

datetime.date() - Date
datetime.time() - Time
datetime.datetime() - Date and time

8.4.1. SetUp

>>> from datetime import date, time, datetime

8.4.2. Current Datetime

datetime.now() - current date and time

Create datetime object with current date and time:

>>> x = datetime.now()
>>>
>>> print(x)
2000-01-02 03:04:05.000006

8.4.3. Current Date

date.today() - current date

Create date object with current date:

>>> x = date.today()
>>>
>>> print(x)
2000-01-02

8.4.4. Current Time

There is no time.now()

There is no time.now(), but you can get current time from datetime.now():

>>> x = datetime.now().time()
>>>
>>> print(x)
03:04:05.000006
