Python有静态对象、堆栈对象和堆对象吗？

Question

来自编程语言语用学，斯科特

Object lifetimes generally correspond to one of three principal storage allocation mechanisms, used to manage the object’s space:

1. Static objects are given an absolute address that is retained throughout the program’s execution.

2. Stack objects are allocated and deallocated in last-in, first-out order, usually in conjunction with subroutine calls and returns.

3. Heap objects may be allocated and deallocated at arbitrary times. They require a more general (and expensive) storage management algorithm.

C语言有静态对象、堆栈对象和堆对象。在

Python有静态对象、堆栈对象和堆对象吗？在

我看到了in another postCPython分配堆上的所有对象。这是否意味着Python中的所有对象都是堆对象？在

但是Python也有静态方法。Python中的静态方法是静态对象吗？在

谢谢。在

Answer 1

Python对象大多是堆对象，但是在CPython中有一些特殊的PyObject singleton值在C中是static，但这是实现细节。例如，通常的内置类型具有静态存储持续时间。据我所知，没有堆栈（Python）对象。在

静态存储持续时间与静态方法完全无关。在
