Python提供了多个内置模块用于操作日期时间,像calendar,time,datetime。datetime模块用于是date和time模块的合集,他内部重新封装了time模块,相比于time模块,datetime模块的接口则更直观、更容易调用。 datetime模块定义了两个常量:datetime.MINYEAR和datetime.MAXYEAR,分别表示datetime所能表示的最小、最大年份。 其中:MINYEAR...
date.today():返回一个表示当前本地日期的date对象;date.fromtimestamp(timestamp):根据给定的时间戮,返回一个date对象;datetime.fromordinal(ordinal):将Gregorian日历时间转换为date对象;(Gregorian Calendar :一种日历表示方法,类似于我国的农历,西方国家使用比较多,此处不详细展开讨论。) 使用例子: date提供的实例方...
Python的time和datetime模块提供了时间日期工具, python中的时间有4种表示方式: datetime obj time obj/tuple posix timestamp timestring time 时间相关的操作,时间有三种表示方式: 时间戳 1970年1月1日之后的秒,即:time.time() 格式化的字符串 2014-11-11 11:11, 即:time.strftime('%Y-%m-%d') 结构...

Python'sdatetimemoduleis great: It hasordinalandtimestampas absolute values, anddateanddatetimeas nominal ones for the Gregorian calendar. The only issue istimedelta: It is really an absolute delta, so basically the same asdate1.toordinal() - date2.toordinal()ordt1.timestamp() - dt2.timest...

Nowadays, a lot of applications are time-sensitive and hence require effective date and time management. Python provides many libraries to handle this task, and one of the most effective is Pendulum. Pendulum inherits from its parentDateTimelibrary with a more intuitive interface. The library offers...
