the module nameA.Bdesignates a submodule namedBin a package namedA. Just like the use of modules saves the authors of different modules from having to worry about each other’s global variable names, the use of dotted module names saves the authors of multi-module packages...
The effect of a singleton is usually better implemented as a global variable inside a module. Class decorators are less common than function decorators. You should document these well, so that your users know how to apply them.Caching Return Values...

Notice that the only non-static name in the hello.c example C file is the initialization function. Python calls this function by name after loading the object file, so its name must be a C global and should generally be of the form initX, where X is both the name of the module in ...
(static) global variables, or when the extension manipulates its module's dictionary after its initialization. It is possible to insert objects created in one sub-interpreter into a namespace of another sub-interpreter; this should be done with great care to avoid sharing user-defined functions,...
Restore the thread state from the local variable. 具体到实际代码如下: PyThreadState*_save;_save=PyEval_SaveThread();#该接口返回线程状态并释放GIL...DosomeblockingI/Ooperation...PyEval_RestoreThread(_save); 从这里可以看出,全局解释器锁是用来保护一个全局变量,该全局变量指向线程的状态数据。

如果class定义中不存在__metaclass__的话,Python将会寻找MODULE级别的__metaclass__。如果存在的话鸠进行与前述相同的操作。但是只有我们定义的class没有继承任何类的情况下,Python才会在MODULE级别寻找__metaclass__。或者说,只有当该类是一个旧类的情况下,Python才会在MODULE级别寻找__metaclass__。(关于新类和旧...
