Python如何通过变量ID得到变量的值

from _ctypes import PyObj_FromPtr
 
def di(obj_id):
    """ 通过变量ID 得到变量的值"""
    return PyObj_FromPtr(obj_id)
 
if __name__ == "__main__":
    i = {"j":99,"name":"jack"}
    var_id = id(i)
    print(var_id)
    print (di(var_id))

import ctypes
 
value='hello world' #定义一个字符串变量
address=id(value) #获取value的地址，赋给address
get_value=ctypes.cast(address, ctypes.py_object).value #读取地址中的变量
print(get_value)
