Python 64-bit can't load 32-bit libraries without some heavy hacks running another Python, this time in 32-bit, and using IPC. If you have to load DLLs that you compile yourself, you'll have to compile them to 64-bit, which is usually harder to do (specially if using MinGW on Windows).
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)
1 dzień temu · Four Python 3.13 installers are available for download - two each for the 32-bit and 64-bit versions of the interpreter. The web installer is a small initial download, and it will automatically download the required components as necessary.
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.
Python comes in both 32- and 64-bit editions. Which one should you choose, and what difference will it make?
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.
10 wrz 2021 · The output is either "32" or "64" depending on whether you run a 32-bit or 64-bit Python version: # Output: # "32" for a 32-bit installation, or "64" for 64-bit. 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.
