Python Incorrectly Detects 32-bit System On Windows 8.1 64-bit

PS C:\Users\************> C:\Python27\python.exe Python 2.7.15 (v2.7.15:ca079a3ea3, Apr 30 2018, 16:30:26) [MSC v.1500 64 bit (AMD64)] on win32 Type 'help', 'copyright', 'credi

Solution 1:

win32 doesn't necessarily mean your windows is a 32bit system, It means you are on windows operating system, And it is just left there for historical reasons. And the properties on your This PC are enough to confirm it is 64bit windows. There is no win64 btw.

The line you are looking for is this, [MSC v.1500 64 bit (AMD64)] - Meaning it was built with MSVC compiler for 64-bit

and to more reliably check for if your interpreter is running as 32bit or 64bit try this,

import sys
print(sys.maxsize > 2**32) # must return TRUE for64bit
