常用日期方式

from datetime import datetime
import time

#python里使用time模块来获取当前的时间

print (time.strftime("%H:%M:%S"))    ##24小时格式 :21:45:33
print (time.strftime("%H-%M-%S"))    ##24小时格式 :21-50-01

print (time.strftime("%I:%M:%S"))  ## 12小时格式 :09:45:33
print (time.strftime("%I-%M-%S"))  ## 12小时格式 :09-49-33
#--------------------------------------------------------------------------

## dd/mm/yyyy格式

print (time.strftime("%d/%m/%Y"))   #:27/02/2020
print (time.strftime("%Y/%m/%d"))   #:2020/02/27
print (time.strftime("%Y-%m-%d"))   #:2020-02-27

#--------------------------------------------------------------------------

print (time.strftime("%Y-%m-%d-%I-%M-%S"))   #:2020-02-27-09-51-02

print(type(time.strftime("%Y-%m-%d-%I-%M-%S")))  #:<class 'str'>

#--------------------------------------------------------------------------
print(datetime.now())      #:2020-02-27 21:51:36.752944

print(time.asctime())      #Thu Feb 27 21:51:36 2020

#--------------------------------------------------------------------------

cur=datetime.now()

print(cur.year)  #:2020

print(cur.month)  #:2

print(cur.day)  #:27

print(cur.hour)  #:21

print(cur.minute)  #:56

print(cur.second)  #:5

#--------------------------------------------------------------------------
