ERLANG和PYTHON互通实现过程详解

最近开发Erlang,对其字符串处理能力无言至极,于是决定把它和python联合起来,打造一个强力的分布式系统,等将来需要系统级开发时,我再把C++/C组合进来.首先参考了Erlang官方文档和http://blog.developers.api.sina.com.cn/?tag=erlang以及http://kazmier.net/computer/port-howto/.研读了将近24个小时,才终于完全把问题解决.起名为town，town在英文里表示集

讲解Python中if语句的嵌套用法

可能有这样一种情况，当你想检查其他条件后一个条件解析为真。在这种情况下，可以使用嵌套的if结构。在嵌套的if语句结构，可以在一个if...elif...else结构里面可有另外一个if...elif...else结构。语法：嵌套if...elif...else结构的语法可以是：ifexpression1:statement(s)ifexpression2:statement(s)elifexpression3:statement(s)elsestateme

python实现进程间通信简单实例

本文实例讲解了python实现两个程序之间通信的方法，具体方法如下：该实例采用socket实现，与socket网络编程不一样的是socket.socket(socket.AF_UNIX,socket.SOCK_STREAM)的第一个参数是socket.AF_UNIX而不是socket.AF_INET例中两个python程序s.py/c.py要先运行s.py基于fedora13/python2.6测试，成功实现！s.py代码如下：#!/usr/bin/env

Python3基础之条件与循环控制实例解析

本文实例形式讲解了Python3的条件与循环控制语句及其用法，是学习Python所必须掌握的重要知识点，现共享给大家供大家参考。具体如下：一般来说Python的流程控制语句包括：if条件语句、while循环语句、for循环语句、range函数以及break、continue、pass控制语句。这些语句在Python中的语义和在其他语言中基本是一样的，所以这里就只说它们的用法。一、if语句if语句是最常用的条件控制语句，Python中的一般形式为：if条件一

手机游戏中的闪烁

昨日等车无聊时，打开手机，玩起了自己做的一款手机游戏。突然想起以前写代码的趣事。记得当时写代码写到天昏地暗，突然遇到瓶径，如何解决闪烁问题。也许是长时间写代码的原因，大脑有点缺氧，百思居然不得其解。于是上网查找，居然无解...仔细一想，网上既然无解。那只有两种可能：要么就是太简单，不是问题；要么就是太复杂无人能解。显然不是后者...悲剧，难道我一向自负的天资出卖了我就在这时。停电了...我恍然大悟，原来我把简单的事情弄复杂了，闪烁其实没有那么复杂。setv

TextInput、RadioButton、CheckBox、Combobox组

一。TextInput组件就是文本输入框，参数有1。editable,默认是true,为文本可编辑，false,为输入文本不可编辑。2。password,是否为密码字段，默认为false,不是，如果为true时，是密码字段。3。text就是要填的文本字段。二。RadioButton组件就是单选框，就是在某个问题的一组答案中，只有一个被选中，参数有组名称等，具体：1。data:就是输入RadioButton组件实例的label值。2。groupName:组名
