想要了解PyInt_Type的相关信息,我们可以打开intobject.c,并找到如下内容: PyTypeObject PyInt_Type = { PyObject_HEAD_INIT(&PyType_Type) 0, "int", sizeof(PyIntObject), 0, (destructor)int_dealloc, /* tp_dealloc */ (printfunc)int_print, /* tp_print */ 0, /* tp_getattr */ 0, /* ...
Return the “identity” of an object. This is an integer which is guaranteed to be unique and constant for this object during its lifetime. Two objects with non-overlapping lifetimes may have the sameid()value. CPython implementation detail:This is the address of the object in memory. ...

面向对象的程序设计:核心是对象二字,(要理解对象为何物,必须把自己当成上帝,上帝眼里世间存在的万物皆为对象,不存在的也可以创造出来。面向对象的程序设计好比如来设计西游记,如来要解决的问题是把经书传给东土大唐,如来想了想解决这个问题需要四个人:唐僧,沙和尚,猪八戒,孙悟空,每个人都有各自的特征和技能(这就是...
转:http://www.cnblogs.com/Lvkun/archive/2012/03/01/python_object_memory_usage.html Python 对象内存占用 (github地址) 之前写的脚本中,需要估计程序的内存占用,所以简单研究下Python各种对象在内存中占用大小。 本人对 Python 一直处在使用的阶段,没有进行深入研究。所以有什么错误还请指出,欢迎交流。
