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.
Apr 16, 2015 · While it may work on some platforms, be aware that platform.architecture is not always a reliable way to determine whether python is running in 32-bit or 64-bit. In particular, on some OS X multi-architecture builds, the same executable file may be capable of running in either mode, as the example below demonstrates.
The term “win32” is often used to refer to the programming interface for the Microsoft Windows operating system, and it has been maintained for compatibility reasons even in 64-bit versions of Windows. Even though you have a 64-bit version of Python installed on a 64-bit Windows instance, the reference to “win32” is used to indicate ...
2 days ago · Using Python on Windows — Python 3.13.0 documentation. 4. Using Python on Windows ¶. This document aims to give an overview of Windows-specific behaviour you should know about when using Python on Microsoft Windows. Unlike most Unix systems and services, Windows does not include a system supported installation of Python.
Apr 9, 2024 · You can use the same approach to check if the Python interpreter is running 32-bit or 64-bit from inside a script. The sys.maxsize > 2**32 expression returns True if the Python interpreter runs as 64-bit and False if it runs as 32-bit. This is the approach that the documentation recommends. The sys.maxsize attribute returns an integer that is ...
Sep 10, 2021 · Here’s the explanation of the arithmetic approach to calculate the Python bit version: The struct module converts data between Python values and C structs using Python bytes objects. The string argument "P" represents a generic pointer in C. Here’s the gist: a pointer has 4 bytes on a 32-bit system, and 8 bytes on a 64-bit system.

How to Check if the Running Python or OS Is 64-Bit. To check if the Python interpreter is 64-bit the official documentation suggests: >>> import sys. >>> is_64bits = sys.maxsize > 2**32. >>> is_64bits. True. Note that a 32-bit Python interpreter can be installed on a 64-bit operating system. To find out if the operating system is 64-bit, use ...
