I don't think that will satisfy the OP. Apparently, he wants to find
out that the system is "running on 64bit" even when the interpreter is a
32-bit build executable ("what python was built on").
I don't think Python supports querying that information in general
(i.e. "is the microprocessor supporting a 64-bit address space, even
if the current process, and perhaps the current operating system
only uses a 32-bit address space?")
It is possible to answer that question with Python in a
platform-specific manner, but the answer is more difficult than a
single yes/no:
- is the processor capable of executing 64-bit code?
- is the operating system kernel operating the processor in 64-bit
mode?
- does the operating system support 64-bit user-space applications?
(in some OSX and Solaris releases, the answer to this question
was no, even though the answer to the previous question was yes,
IIRC)
- does the Python binary support 64-bit mode?
- is the Python binary running in 64-bit mode?
(again, this may vary from the previous question, in case of
fat (universal) binaries)
Whether any of these questions are of interest, and which of them
the OP wanted to ask, I don't know.

Martin
