Re: [Pythonmac-SIG] machine architecture 32/64 with Python 2.6 on Snow Leopard?
I looked into the code for platform.architecture(), and it basically
runs the file command on /usr/bin/python. If the output contains
the string 64-bit, it will return 64bit as the first tuple. So it
depends on what real question you are trying to answer, because in
SnowLeopard, /usr/bin/python is a wrapper program that does all the
versioning, reading preference files, etc, and is independent of the
real python executable: /System/Library/Frameworks/Python.framework/
Versions/2.6/Resources/Python.app/Contents/MacOS/Python.
Testing sys.maxint answers the question whether the current python in
running in 32 or 64-bit mode. platform.architecture() just tells if
the wrapper is capable of running 64-bit (it will run 64-bit by
default on 64-bit architectures, but could actually be running 32-bit,
either by choice or on 32-bit only hardware), and doesn't say anything
about the real python executable.

Hmmm. So what's the pythonic way of getting i386 vs. x86_64?
{'32bit': 'i386', '64bit': 'x86_64'}[platform.architecture()[0]]
seems so complicated that there should be a routine for it in sys or
platform.
I don't know the official way, but what I do is:
% python -c 'import sys;print sys.maxint'
9223372036854775807
% env VERSIONER_PYTHON_PREFER_32_BIT=1 python -c 'import sys;print

You could also use other test I've seen:
def arch():
import ctypes
return {4: i386, 8: x86_64}[ctypes.sizeof(ctypes.c_size_t)]

If you run the CLI 'uname -m' on any Intel Mac, it always has returned
i386. So all it really means is 'Intel'.
