Ok, I closed my PR 11186 which modified architecture() to only return struct.calcsize('P') if the executable argument is equal to sys.executable.

> 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.

I see the platform module as a module to get info about the operating system and Python, but it seems like I misunderstood the purpose of the specific case of the architecture() function.

I propose a small addition to the doc to avoid confusion:
