问题描述
我有一个计划中的项目，我想拥有的一点信息是 reference 在Python中占用了多少内存. AFAIK，Python中的引用与指针相同，我猜想它的大小与32位或64位指针相同(但我可能错了).
I have a project that I am planning, and one bit of information I'll want to have is how much memory a reference takes up in Python. AFAIK, a reference in python is the same as a pointer, and I am guessing that it would be the same size as a 32bit or 64bit pointer (but I could be wrong).
任何人都可以帮我解决这个问题，这样我就不必继续猜测了吗?
Could anyone clear this up for me, so that I don't have to go on guesswork?
推荐答案
在评论中，我和SuperBiasedMan进行了讨论. Python中引用的大小与CPU的字大小相同.因此，在32位python版本上为4个字节，在64位python版本上为8个字节.
This was answered in the comments through a discussion between me and SuperBiasedMan. The size of a reference in Python is the same as the word size for the CPU. So, it's 4 bytes on a 32bit build of python, and 8 bytes on 64bit python.
