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)

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.
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:
To check whether Python is 64-bit or 32-bit on your system, you can use the following Python code: import sys if sys.maxsize > 2**32: print("Python is running as 64-bit") else: print("Python is running as 32-bit")
