I recently installed Python 3.1 and the Pygame module for Python 3.1 When I type import python in the console I get the following error:
Traceback (most recent call last): File "<pyshell#2>", line 1, in <module> import pygame File "C:\Python31\lib\site-packages\pygame\__init__.py", line 95, in <module> from pygame.base import * ImportError: DLL load failed: %1 is not a valid Win32 application.
It could be due to the architecture of your OS. Is your OS 64 Bit and have you installed 64 bit version of Python? It may help to install both 32 bit version Python 3.1 and Pygame, which is available officially only in 32 bit and you won't face this problem.
I see that 64 bit pygame is maintained here, you might also want to try uninstalling Pygame only and install the 64 bit version on your existing python3.1, if not choose go for both 32-bit version.
