Question

I have problem with pygame and python 3 in ubuntu 12.10. When i tried load an image i got this error:

pygame.error: File is not a Windows BMP file

But in python 2.7 all works fine.
I use code from http://inventwithpython.com/chapter19.html

Sorry for my poor English.

Answer 1

The Ubuntu released repo specifically shows Python 2.7 as a dependency of PyGame 1.6.1 which is the current version in the Ubuntu Released repo. It may just be the only version of Python supported by the package.

To see this info yourself try apt-cache depends python-pygame.
