Guys, please read the doc-string of the platform.architecture() function (or ask the person who wrote most of the module). It clearly refers to inspecting a specific executable and only uses the Python interpreter as default.

The running process can provide some sane defaults, but is not necessarily using the same values as the given executable.

The function does not support multi-architecture executables. This is simply out of scope for the function.

Victor: AFAIK, I still own this module, so if you want to deprecate something, please ping me first.
