datetime.date(2020, 3, 12)

 

 

# 访问日期

datetime.date(2020, 3, 12)

>>> datetime.date.today().year

2020

>>> datetime.date.today().month

3

>>> datetime.date.today().day

12

 

 

>>> datetime.date.today().__getattribute__("year")

2020

>>> datetime.date.today().__getattribute__("month")

3

12

 

# 返回星期几

# 周一到周日，1到7

>>> datetime.date.today().isoweekday()

4

 

# 周一到周日，0到6

>>> datetime.date.today().weekday()

3

 

 

 

 

# 日期的格式化

>>> datetime.date(2020,3,13).isoformat()

'2020-03-13'

 

>>> datetime.date(2020,3,13).__str__()

'2020-03-13'

 

 

>>> datetime.date(2020,3,13).ctime()

'Fri Mar 13 00:00:00 2020'

 

>>> datetime.date(2020,3,13).strftime("%Y-%d-%m")

'2020-13-03'

 

>>> datetime.date(2020,3,13).__format__("%Y-%d-%m")

'2020-13-03'

 

 

# 时间操作 time

 

# 同时操作时间和日期

>>> datetime.datetime.now().__str__()

'2020-03-12 10:30:21.929071'

 

>>> datetime.datetime.now().isoformat()

'2020-03-12T10:30:30.457183'

 

>>> datetime.datetime.now().ctime()

'Thu Mar 12 10:30:38 2020'

 

>>> datetime.datetime.now().strftime("%Y-%d-%m %H-%M-%S")

'2020-12-03 10-31-47'

 

>>> datetime.datetime.now().__format__("%Y-%d-%m %H-%M-%S")

'2020-12-03 10-32-10'

 

# 两个时间点的差值

(a + datetime.timedelta(hours = 8)).ctime()

 

 

>>> a = datetime.datetime.now()

>>> b = datetime.datetime.now()

 

>>> (a - b).days

-1

 

>>> (a - b).seconds
