On a 32-bit system, it would return 4 bytes. On a 64-bit system, it would return 8 bytes. So the following would return 32 if you're running 32-bit python and 64 if you're running 64-bit python: Python 2. import struct;print struct.calcsize("P") * 8 Python 3. import struct;print(struct.calcsize("P") * 8)
24 sie 2011 · I'm running python 2.6 on Linux, Mac OS, and Windows, and need to determine whether the kernel is running in 32-bit or 64-bit mode. Is there an easy way to do this? I've looked at platform.machine(), but this doesn't work properly on Windows.
9 kwi 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.
One simple way of checking if Python is running 32-bit or 64-bit is by using the python -c command. Open a terminal window and type python -c 'import struct; print(struct.calcsize("P") * 8)' (without the quotes). This will tell you whether you are running a 32-bit or 64-bit version of Python.
26 paź 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
5 mar 2020 · If you run this in a 32 bit process on 64 bit Windows, PROCESSOR_ARCHITEW6432 is 'AMD64' and PROCESSOR_ARCHITECTURE is 'x86'. So this really tests for a 64 bit PROCESS, not the OS. – nerdfever.com
You can also run the below python script to check if python is 32 or 64-bit version. # First import struct module. >>> import struct >>> # Return 64 means 64-bit version, return 32 means 32-bit version. >>> version = struct.calcsize("P")*8 >>> >>> print(version) 64
