使用time.strftime（）：

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

方法1：从系统datetime获取当前日期和时间

datetime模块提供用于操作日期和时间的类。

密码

from datetime import datetime,date

print("Date: "+str(date.today().year)+"-"+str(date.today().month)+"-"+str(date.today().day))
print("Year: "+str(date.today().year))
print("Month: "+str(date.today().month))
print("Day: "+str(date.today().day)+"\n")

print("Time: "+str(datetime.today().hour)+":"+str(datetime.today().minute)+":"+str(datetime.today().second))
print("Hour: "+str(datetime.today().hour))
print("Minute: "+str(datetime.today().minute))
print("Second: "+str(datetime.today().second))
print("MilliSecond: "+str(datetime.today().microsecond))

输出将如下

Date: 2020-4-18
Year: 2020
Month: 4
Day: 18

Time: 19:30:5
Hour: 19
Minute: 30
Second: 5
MilliSecond: 836071

方法2：如果网络可用，则获取当前日期和时间

urllib包帮助我们处理url，即网页。这里我们从网页收集数据http://just-the-time.appspot.com/并使用包日期解析器从网页解析日期时间。

密码

from urllib.request import urlopen
import dateparser

time_url = urlopen(u'http://just-the-time.appspot.com/')
datetime = time_url.read().decode("utf-8", errors="ignore").split(' ')[:-1]
date = datetime[0]
time = datetime[1]

print("Date: "+str(date))
print("Year: "+str(date.split('-')[0]))
print("Month: "+str(date.split('-')[1]))
print("Day: "+str(date.split('-')[2])+'\n')

print("Time: "+str(time))
print("Hour: "+str(time.split(':')[0]))
print("Minute: "+str(time.split(':')[1]))
print("Second: "+str(time.split(':')[2]))

输出将如下

Date: 2020-04-18
Year: 2020
Month: 04
Day: 18

Time: 14:17:10
Hour: 14
Minute: 17
Second: 10

方法3：从机器的本地时间获取当前日期和时间

Python的时间模块提供了一个函数，用于从称为localtime（）的历元起经过的秒数获取本地时间。ctime（）函数将从epoch开始经过的秒数作为参数，并返回表示本地时间的字符串。

密码

from time import time, ctime
datetime = ctime(time()).split(' ')

print("Date: "+str(datetime[4])+"-"+str(datetime[1])+"-"+str(datetime[2]))
print("Year: "+str(datetime[4]))
print("Month: "+str(datetime[1]))
print("Day: "+str(datetime[2]))
print("Week Day: "+str(datetime[0])+'\n')

print("Time: "+str(datetime[3]))
print("Hour: "+str(datetime[3]).split(':')[0])
print("Minute: "+str(datetime[3]).split(':')[1])
print("Second: "+str(datetime[3]).split(':')[2])

输出将如下

Date: 2020-Apr-18
Year: 2020
Month: Apr
Day: 18
Week Day: Sat

Time: 19:30:20
Hour: 19
Minute: 30
Second: 20

这就是我最终要做的：

>>>from time import strftime
>>>strftime("%m/%d/%Y %H:%M")
01/09/2015 13:11

此外，该表是选择适当格式代码以按照您想要的方式格式化日期的必要参考（来自Python“datetime”文档）。

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。

获取当前日期时间属性：

import datetime

currentDT = datetime.datetime.now()

print ("Current Year is: %d" % currentDT.year)
print ("Current Month is: %d" % currentDT.month)
print ("Current Day is: %d" % currentDT.day)
print ("Current Hour is: %d" % currentDT.hour)
print ("Current Minute is: %d" % currentDT.minute)
print ("Current Second is: %d" % currentDT.second)
print ("Current Microsecond is: %d" % currentDT.microsecond)


#!/usr/bin/python
import time;

ticks = time.time()
print "Number of ticks since "12:00am, Jan 1, 1970":", ticks

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)
