gentoo.cn,您好！ 我想这个东西大概估一下就好了。如果想严格控制，还不如做成扩展库来的方便呢。用C或其它可以对内存控制的语言编一个扩展库，在python中再进行调用好了。毕竟不会要求，什么东西都考虑内存吧。只有在关键的地方才会考虑吧。 ======= 2004-08-10 16:38:23 您在来信中写道：======= >一般来说，使用python, java这样有gc的程序时不用关心内存分配（memory killer) >但是，有的应用场合可能你需要关心object的大小 >比如：类似于Zope这样的Object容器里的Cache, 太大的Object不要放到Cache里来 > >抑或，有个叫pythonOS的东东里可能也需要哦。 > >limodou wrote: > >>Zoom.Quiet,您好！ >> >> 也不至于要细到要知道内存大小。 >> >>======= 2004-08-10 15:54:28 您在来信中写道：======= >> >> >> >>>Hollo limodou: >>> >>> 不能说不关心哪？！ >>>Python 在嵌入设置中也有移植的！性能的追求是一切语言不能忽略的是也乎，不过 Python 以另外的方式来完成，当然也有提高的余地，有忐者可以开始探险哪！？ >>> >>> >>>/******** [2004-08-10]15:52:50 ; limodou wrote: >>> >>>limodou> tocer,您好！ >>> >>>limodou> 因为使用Python根本不关心这个。不要总把C/C++里的概念在Python中使用，因为它们根本就不一样。 >>> >>>limodou> ======= 2004-08-10 15:33:00 您在来信中写道：======= >>> >>> >>> >>>>>没想到这么难解决 >>>>> >>>>>----- Original Message ----- >>>>>From: "gentoo.cn" <gentoo.cn at 126.com> >>>>>To: <python-chinese at lists.python.cn> >>>>>Sent: Tuesday, August 10, 2004 12:53 PM >>>>>Subject: Re: [python-chinese] 如何测量一个变量或者常量在内存中的大小 >>>>> >>>>> >>>>> >>>>> >>>>>>找到一个相关的讨论 >>>>>>http://www.egenix.com/mailman-archives/egenix-users/2002-November/000156.html >>>>>> >>>>>>gentoo.cn wrote: >>>>>> >>>>>> >>>>>> >>>>>>>我的意思是：是不是可以通过计算一个Object的Struct来猜测这个Object的大小？ >>>>>>>比如c='a', string="abcd" >>>>>>>那么c的类型是1c, string的类型是4c >>>>>>>calcsize('c')=1 >>>>>>>calcsize('L')=4 >>>>>>>也就是说一个数值型的对象占用4Bytes内存空间，一个字符型对象占用1Bytes内存 >>>>>>>空间？ >>>>>>>对于string="abcd"这个对象，类型是4c所以占用4Bytes内存空间？ >>>>>>>不知道Python如何考虑对齐的（也许他最小的单位是1Bytes所以都是8bit的倍数， >>>>>>>这样就对齐了？） >>>>>>> >>>>>>>大家都来讨论讨论啊。 >>>>>>> >>>>>>> >>>>>>> >>>>>>>limodou wrote: >>>>>>> >>>>>>> >>>>>>> >>>>>>> >>>>>>> >>>>>>>>gentoo.cn,您好！ >>>>>>>> >>>>>>>> >>>>>>>> >>>>>>>> >>>>>>那个不是内存的大小吧。而是对应的struct的大小。因为在python中都是对象，而不仅仅是数据结构。不知道:你想知道内存大小有什么用？ >>>>>> >>>>>> >>>>>>>>======= 2004-08-10 11:05:42 您在来信中写道：======= >>>>>>>> >>>>>>>> >>>>>>>> >>>>>>>> >>>>>>>> >>>>>>>> >>>>>>>> >>>>>>>>>import struct >>>>>>>>>struct.pack >>>>>>>>>struct.calcsize ?
