How to determine machine architecture in Python? [duplicate]

Question

I'm wondering how to find the architecture of the machine python is running on and save it to a string. The only other example I've been able to find works only on Windows, and doesn't even detect the proper architecture if it's Windows on Arm. Any solutions would be greatly appreciated.

Thanks,
NullUsxr

What have you tried? Have you seen docs.python.org/3/library/platform.html? — Iain Shelvington

It gives the wrong architecture type when ran on arm. The output of the universal command is ('64bit', ''), despite my system architecture being aarch64. — NullUsxr

Have you explored all the functions in the module? platform.machine() or platform.processor() seem like they might give you what you want? — Iain Shelvington

platform.machine() surprisingly returns the correct value of 'arm64'! Thank you! — NullUsxr

Do any of the answers on Is there a reliable way to determine the system CPU architecture using Python? or How can I return system information in Python? help? or How to collect current architecture in Python 3, in a way that is portable across Linux, Windows and MacOS? ? — Peter Cordes

import platform
print(platform.system())

According to https://docs.python.org/3/library/platform.html#platform.system it says the function would "Returns the system/OS name, such as 'Linux', 'Darwin', 'Java', 'Windows'. An empty string is returned if the value cannot be determined."

Good idea, though it doesn't tell me if 'Darwin' or 'Windows', etc. is 32-bit, 64-bit, aarch64 and so on. Using platform.architecture(executable=sys.executable, bits='', linkage='') from the same source as yours, also returns an invalid value if on the aarch64 architecture.
