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.
2 days ago · On 64-bit Windows with both 32-bit and 64-bit implementations of the same (major.minor) Python version installed, the 64-bit version will always be preferred. This will be true for both 32-bit and 64-bit implementations of the launcher - a 32-bit launcher will prefer to execute a 64-bit Python installation of the specified version if available.
Oct 26, 2022 · The following Python script can be used to determine whether the Python shell is executing in 32bit or 64bit mode. The code was compiled successfully and it gave the result. Method 1: Using Platform Packages. Here we are going to use platform packages to get the mode of or the os. architecture() methods from the platform packages return the ...
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 gist: a pointer has 4 bytes on a 32-bit system, and 8 bytes on a 64-bit system. The calcsize() function calculates the number of bytes for the pointer and multiplies it with 8 because 4*8 = 32 for a 32-bit system and 8*8 = 64 for a 64-bit system. Thus, struct.calcsize("P") returns your “Python Bit Version”. Where to Go From Here?

You can determine whether your Python interpreter is running in 32-bit or 64-bit mode by checking the value of the sys.maxsize attribute. In a 64-bit Python interpreter, sys.maxsize will be a large positive number, while in a 32-bit Python interpreter, it will be a smaller positive number. Here's how to check it:
