When you use the raise statement in Python to raise (or throw) an exception, you signal an error or an unusual condition in your program. With raise, you can trigger both built-in and custom exceptions. You can also include custom messages for more clarity or even re-raise exceptions to...
You can specify callbacks during initialization by passing them to a State object constructor, in a state property dictionary, or add them later.For convenience, whenever a new State is added to a Machine, the methods on_enter_«state name» and on_exit_«state name» are dynamically ...

选项 作用-c cmd 在命令行直接执行python代码。如python -c'print "hello world"'。-d 脚本编译后从解释器产生调试信息。同PYTHONDEBUG=1。-E 忽略环境变量。-h 显示python命令行选项帮助信息。-i 脚本执行后马上进入交互命令行模式。同PYTHONINSPECT=1。-O 在执行前对解释器产生的字节码进行优化。同 PYTHONOPTIM...
本文主要分享一下博主在学习wxpy 的过程中开发的一个小程序。博主在最近有一个监控报警的需求需要完成,然后刚好在学习wxpy 这个东西,因此很巧妙的将工作和学习联系在一起。 博文中主要使用到的技术设计到Python,Redis,以及Java。涉及到的技术看似很多,但是主要的语言是基于Python进行开发的。

为了实现一个可修改的集合,程序员必须另外重写这个类的add方法(否则会抛出不支持运行异常UnsupportedOperationException),迭代器方法返回的迭代器必须另外实现它的remove方法。 The programmer should generally provide a void (no argument) and Collection constructor, as per the recommendation in the Collection interface...
