hello, :) this is just a bit of amusement, i'll post my current question in another thread... please don't critique my style or lack of classes/objects in the code yet - i'm way too new. :) my current project is at: https://salsa.debian.org/ant-guest/gfpoken-in-python/ https://salsa.debian.org/ant-guest/gfpoken-in-python/tree/next i'm using pyglet (most recent version) and gtk... the amusing bit: working on my git next branch... in my_sprite.py if i take the self out of on_animation_end parentheses i get this error message: TypeError: The 'on_animation_end' event was dispatched with 0 arguments, but the handler 'on_animation_end' at /home/me/src/salsa/ngfp/my_sprite.py:23 is written with 0 arguments. 0 <> 0 !!!!! :) songbird
