One way is to look at sys.maxsize as documented here: $ python-32 -c 'import sys;print("%x" % sys.maxsize, sys.maxsize > 2**32)' ('7fffffff', False) $ python-64 -c 'import sys;print("%x" % sys.maxsize, sys.maxsize > 2**32)' ('7fffffffffffffff', True) On Windows, run the same commands formatted as follows:

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:
You can detect whether Python is running as a 64-bit application or a 32-bit application by checking the value of the sys.maxsize attribute. In a 64-bit Python environment, sys.maxsize will be equal to 9223372036854775807, whereas in a 32-bit Python environment, it will be equal to 2147483647.
