Why is Python 2.7 in 32 bit mode?

hash(X) is 32 bit

a=array.array("L")
a.append(1)
len(a.tostring()) == 4

Python 2.5 was in 64 bit mode.

This makes my migration much harder :(

Is there a plan to support Python 2.7 in 64bit mode?

Cheers,

Thanks a lot for the reply.

Is there an issue about it?

Or how do you know that Google knows
about it and is going to change it?

I'm sorry, I skipped the comment section
and didn't see that Guido commented it.

Thanks a lot for the help.

Maybe you still want to star the issue...

That bug is unrelated to the subject of this thread (but we are aware of it).

Hi Andrin,

No, sorry. The Python 2.7 was compiled in 32-bit mode by design and we
don't plan on supporting a 64-bit Python 2.7 build.

Cheers,
Brian

There are various technical reasons that we aren't in a position to detail.

So this is what the old Celeron 600 machines Google used to have are
used for.

Ok, good to know it was an informed
decision and it will stay this way.

Bye Bye 64bit, I liked you.

Cheers,
