Python中超过1个字节对象的相同内存地址

如果内存地址参考1内存的字节，则如果我将元素附加到该列表，则如何表示“ 139754451527680”的内存地址保持不变？

为了澄清，我了解数组/列表的元素是元素位置的指示

。大于1个字节对象？

如果我们在谈论8个字节对象，只是（内存地址 * 8）吗？

import sys
a = 1
sys.getsizeof(a)  # 28 bytes (24 bytes int overhead; 4 bytes integer value)
id(a)             # 9788960  ---> 28 memory slot / memory addresses????

原文

If a memory address references 1 byte of memory, how does the memory address of say '139754451527680' for an empty list stay the same if I append elements to that list?

To clarify, I understand that elements of an array/list are pointers to the elements location, etc...

My question is specific to if the memory address is the address of 1 byte of memory, how does the address 'get calculated' for larger than 1 byte objects?

Is it just the (memory address * 8) if we are talking about an 8 byte object?

import sys
a = 1
sys.getsizeof(a)  # 28 bytes (24 bytes int overhead; 4 bytes integer value)
id(a)             # 9788960  ---> 28 memory slot / memory addresses????
