sys.getsizeof(obj) 但他不计算object instance的attribute value的大学,因为都是reference 它调用的实际是magic function:__sizeof__(self) 写个程序,计算一下各种对象的大小:classA(object):passclassB:passforxin(None, 1, 1L, 1.2,'c', [], (), {}, set(), B, B(), A, A()):print"{0:2...
} Object { string name int memory_usage } Object--|{sys.getsizeof()}|- sys Object--|{asizeof.asizeof()}|- asizeof 通过以上步骤和代码示例,你应该能够了解如何在Python中查看对象的内存占用。这将有助于你更好地优化程序性能,提高代码的运行效率。
应该增加其引用计数以传递所有权给调用者returnPy_BuildValue("O",new_obj);// 在这里,Py_BuildValue会自动增加引用计数// 当你从函数内部删除一个传入的参数时,减少引用计数voidsome_c_function(PyObject*obj){// 使用完 obj 后Py_DECREF(obj);}
