>>> import datetime, time
>>> time = time.strftime("%H:%M:%S:%MS", time.localtime())
>>> print time
'00:21:38:20S'

最快的方法是：

>>> import time
>>> time.strftime("%Y%m%d")
'20130924'

now（）的属性可用于获取python中的当前时间：

# importing datetime module for now()
import datetime
    
# using now() to get current time
current_time = datetime.datetime.now()
    
# Printing attributes of now().
print ("The attributes of now() are : ")
    
print ("Year : ", end = "")
print (current_time.year)
    
print ("Month : ", end = "")
print (current_time.month)
    
print ("Day : ", end = "")
print (current_time.day)
    
print ("Hour : ", end = "")
print (current_time.hour)
    
print ("Minute : ", end = "")
print (current_time.minute)
    
print ("Second : ", end = "")
print (current_time.second)
    
print ("Microsecond : ", end = "")
print (current_time.microsecond)

import datetime
date_time = str(datetime.datetime.now()).split()
date,time = date_time

date将打印日期，time将打印时间。

import datetime

todays_date = datetime.date.today()
print(todays_date)
>>> 2019-10-12

# adding strftime will remove the seconds
current_time = datetime.datetime.now().strftime('%H:%M')
print(current_time)
>>> 23:38

如果您只希望当前时间戳以毫秒为单位（例如，测量执行时间），也可以使用“timeit”模块：

import timeit
start_time = timeit.default_timer()
do_stuff_you_want_to_measure()
end_time = timeit.default_timer()
print("Elapsed time: {}".format(end_time - start_time))
