Open python console: import platform. platform.architecture()[0] it should display the '64bit' or '32bit' according to your platform. Alternatively ( in case of OS X binaries ): import sys. sys.maxsize > 2**32. # it should display True in case of 64bit and False in case of 32bit. edited Mar 13, 2023 at 7:05.
This will tell you whether you are running a 32-bit or 64-bit version of Python. 1.2 Checking from inside a script using sys.maxsize attribute.
