From Game Maker to Python

I use Game Maker for creating simple (and not simple) 2D games for Windows. I really love it. It's easy to use, it's powerfull and it allows me to create games very fast. But now I know about Python. Python is my new love. I would like to create games using Python now. I would like to have something like Game Maker but with Python inside. Googling "python game engines", I've found these ones: 1) PyGame 2) Cocos2D 3) Blender 4) Python-Ogre Maybe I'm wrong, but I've found that: 1) PyGame is not more powerfull (for Windows) than Game Maker. And the last realese was in 2009. 2) Cocos2D is usually used for creating mobile games with C# and Java. It's not more powerfull than Game Maker too. 3) Blender is 3D engine. Don't think it is a easier way to create 2D games than Game Maker. 4) Python-Ogre -- same as Blender. So, what would you recommend me?
