Python自定义函数计算给定日期是该年第几天的方法示例

本文实例讲述了Python自定义函数计算给定日期是该年第几天的方法。分享给大家供大家参考，具体如下：写一个函数，计算给定日期是该年的第几天．满足闰年的条件：闰年是公历中的名词，能被4整除但不能被100整除，或能被400整除的年份即为闰年。闰年(LeapYear)是为了弥补因人为历法规定造成的年度天数与地球实际公转周期的时间差而设立的。补上时间差的年份为闰年。闰年共有366天（1-12月分别为31天，29天，31天，30天，31天，30天，31天，31天，3

关于myEclipse连接数据库的配置!

下面以mysql举例说明：首先要确保myEclipse插件安装正确。然后点击window->preferences->myEclipse->DatabaseExplorer->Drivers->MySQLConnector/JDriver点击Edit。如下图:Name不需要修改，ExampleURL将主机名和数据库名加上即可,然后点击ExtraClassPath选项卡->点击new将mysql的最新驱动加入进来点点确定即可。如下图:这时回到preferen

测试的基本理论与方法

这些文字是公司一次培训所用的PP资料，觉得讲得很有道理，真正好的软件就必须要这样做，所以抄录了一些记载在自己的Blog上面。一、对软件测试的误解1.如果发布出去的软件有质量问题,那是软件测试人员的错.2.软件测试技术要求不高,至少比编程容易多了3.软件测试随便找一个能力差的人就能做.4.软件测试是测试人员的事,与开发人员无关.5.设计-实现-测试,软件测试是开发后期的一个阶段二、如何理解软件测试软件测试是一种有效的提高软件质量的手段,但即使在投入上有所保证

归结与演绎

1、应用归结之前，wff（合式公式）必须是一个范式或标准形式。范式有三种主要类型：1）合取范式。如：(P1∨P2....)∧(Q1∨Q2...)∧(Z1∨Z2...)2）子句。全子句形式的表达式通常如下：(表示A1,A2,...An全真是，B1，。。。Bn中至少有一个为真)A1,A2,...An->B1,B2,.....Bn3）HORN子句子集。PROLOG使用HORN子句，只允许一个头:A1,A2,....An->B用PROLOG可以写成：B:A1,A2
