By default,persist-queueusepickleobject serialization module to support object instances. Most built-in type, likeint,dict,listare able to be persisted bypersist-queuedirectly, to support customized objects, please refer toPickling and unpickling extension types(Python2) <https://docs.python.org/2/...
5.2 Python解释器里面的main函数首先初始化Python解释器(例如初始化builtin模块,也就是我们直接用的list/dict/None等变量),执行必要的编译操作(把Python代码编译成字节码),然后开始执行Python字节码 5.3 执行结束后,Python调用自己的exit函数销毁Python解释器(比如销毁其中的全部Python变量),其中的最后一步是调用操作系统的...
The mechanism used by the CPython interpreter to assure that only one thread executes Python bytecode at a time. This simplifies the CPython implementation by making the object model (including critical built-in types such as dict) implicitly safe against concurrent access. Locking the entire inte...

First, we need to make sure that RabbitMQ will never lose our queue. In order to do so, we need to declare it as
importqueue defconsumer(name): print("--->starting eating baozi...") whileTrue: new_baozi=yield print("[%s] is eating baozi %s"%(name,new_baozi)) #time.sleep(1) defproducer(): r=con.__next__() r=con2.__next__() n=0 ...
