HomeBackend DevelopmentPython Tutorialpython使用datetime模块计算各种时间间隔的方法

本文实例讲述了python使用datetime模块计算各种时间间隔的方法。分享给大家供大家参考。具体分析如下:

python中通过datetime模块可以很方便的计算两个时间的差,datetime的时间差单位可以是天、小时、秒,甚至是微秒,下面的代码就演示了datetime模块在计算时间差时的强大功能

# -*- coding: utf-8 -*-
#!/usr/bin/env python
import datetime
#datetime一般的时间计算
d1 = datetime.datetime(2013, 8, 05,15,50)
d2 = datetime.datetime(2013, 8, 4,21,9,0,0)
d3 = datetime.timedelta(microseconds=5000)
print u'相差:%s微秒'%(d1-d2).microseconds
print u'相差:%s秒'%(d1-d2).seconds
print u'相差:%s天'%(d1-d2).days
print u'时间间隔:%s微秒'%d3
#时区转换,当前系统所在时区+1
d = datetime.datetime.now()
d = d + datetime.timedelta(seconds=3600)
print d
print d.ctime()

输出结果如下:

相差:0微秒
相差:67260秒
相差:0天
时间间隔:0:00:00.005000微秒

Python vs. C  : Understanding the Key DifferencesPython vs. C : Understanding the Key DifferencesApr 21, 2025 am 12:18 AM

Python and C each have their own advantages, and the choice should be based on project requirements. 1) Python is suitable for rapid development and data processing due to its concise syntax and dynamic typing. 2)C is suitable for high performance and system programming due to its static typing and manual memory management.

Python vs. C  : Which Language to Choose for Your Project?Python vs. C : Which Language to Choose for Your Project?Apr 21, 2025 am 12:17 AM

Choosing Python or C depends on project requirements: 1) If you need rapid development, data processing and prototype design, choose Python; 2) If you need high performance, low latency and close hardware control, choose C.
