My question is: How can I read the content of a memory address in python? example: ptr = id(7) I want to read the content of memory pointed by ptr. Thanks.

推荐答案

看看 ctypes.string_at .这是一个例子.它转储Python 3整数的原始数据结构.希望您只是在做练习.没有理由使用纯Python做到这一点.

Have a look at ctypes.string_at. Here's an example. It dumps the raw data structure of a Python 3 integer. Hopefully you're only doing this as an exercise. No reason to do this with pure Python.

from ctypes import string_at
from sys import getsizeof
from binascii import hexlify
a = 0x7fff 
print(hexlify(string_at(id(a), getsizeof(a))))

输出

b'02000000d8191e1e01000000ff7f'
