There are 2 methods to check if python is 32 or 64-bit version on windows. 1.1 Method 1. Input the keyword cmd in the Windows OS Type here to search text box.
There are different ways of checking the bit-ness of your Python interpreter, such as using the python -c command, sys.maxsize attribute, Windows-specific approach, avoiding platform.architecture method on macOS, and using struct.calcsize() method.
Apr 9, 2024 · Use the python -c "import sys; print(sys.maxsize > 2**32)" command to check if Python is running as 32-bit or 64-bit. The command will return True if Python is running in 64-bit and False if it's running in 32-bit.
Oct 24, 2024 · The simplest way to check if your Python installation is 32-bit or 64-bit is by using the built-in sys module. Here’s how you can do it: import sys. if sys.maxsize > 2**32: print("This is a 64-bit version of Python.") else: print("This is a 32-bit version of Python.")
Nov 6, 2019 · Check if Python interpreter is 32 or 64 bit. 32-bit Python binaries can run on 64-bit OS. To precisely detect if the operating system is 64-bit or 32-bit, check if Python itself is 32-bit to avoid falsely detecting a 64-bit OS as 32 bit. This check is just for the Python interpreter.
