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。

时区的当前时间

from datetime import datetime
import pytz

tz_NY = pytz.timezone('America/New_York') 
datetime_NY = datetime.now(tz_NY)
print("NY time:", datetime_NY.strftime("%H:%M:%S"))

tz_London = pytz.timezone('Europe/London')
datetime_London = datetime.now(tz_London)
print("London time:", datetime_London.strftime("%H:%M:%S"))

tz_India = pytz.timezone('Asia/India')
datetime_India = datetime.now(tz_India)
print("India time:", datetime_India.strftime("%H:%M:%S"))

#list timezones
pytz.all_timezones

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)

使用日期时间：

>>> import datetime
>>> now = datetime.datetime.now()
>>> now
datetime.datetime(2009, 1, 6, 15, 8, 24, 78915)
>>> print(now)
2009-01-06 15:08:24.789150

对于没有日期的时钟时间：

>>> now.time()
datetime.time(15, 8, 24, 78915)
>>> print(now.time())
15:08:24.789150

要保存键入，可以从datetime模块导入datetime对象：

>>> from datetime import datetime

然后删除前缀datetime。从以上所有方面来看。

首先从datetime导入datetime模块

from datetime import datetime

然后将当前时间打印为“yyyy-mm-dd hh:mm:ss”

print(str(datetime.now())

要只获取形式为“hh:mm:ss”的时间，其中ss代表完整的秒数加上所用的秒数，只需执行以下操作即可；

print(str(datetime.now()[11:])

将datetime.now（）转换为字符串，得到的答案格式与我们习惯的常规DATES AND TIMES格式相似。

使用time.strftime（）：

>>> from time import gmtime, strftime
>>> strftime("%Y-%m-%d %H:%M:%S", gmtime())
'2009-01-05 22:14:39'
