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.
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.
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 ...
In this article, we will explore different ways of checking if Python is running 32-bit or 64-bit, as well as the reliability and recommendation of using sys.maxsize > 2**32 expression. 1.1 Using python -c command. One simple way of checking if Python is running 32-bit or 64-bit is by using the python -c command.

Since there are 8 bits in a byte, we multiply this value by 8 to get the total number of bits. Then we compare this value to 64 to determine whether the Python interpreter is running in 64-bit mode or not. Note that this method only works if you are running Python 2. In Python 3, the long type has been removed, so this method will not work.
