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.
Oct 26, 2022 · In this article, we are going to see how to check if the Python shell is executing in 32bit or 64bit mode. 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.
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.

- Where to Go from Here?
In some environments such as macOS or some Linux versions, you may not see the number of bits in the output. You can manually output this using the sys.versioninformation.
You can also calculate it manually in a small two-liner Python script: The output is either "32" or "64"depending on whether you run a 32-bit or 64-bit Python version: 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....
Enough theory. Let’s get some practice! Coders get paid six figures and more because they can solve problems more effectively using machine intelligence and automation. To become more successful in coding, solve more real problems for real people. That’s how you polish the skills you really need in practice. After all, what’s the use of learning th...
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.
It’s a common question, especially when you’re working with different operating systems or trying to debug compatibility issues. Understanding the Problem The architecture of your Python shell, whether it’s 32-bit or 64-bit, determines the size of integers, pointers, and other data types.

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 ...
