Now Python shines xD

I wish there was a tool like cloc that could check the complexity of the implementation (e.g. like radon, but for multiple languages)

Why did you remove the alternative implementation 01_Acey_Ducey/python/acey_ducey_oo.py ? I see no reason why we should not have those? I think it is a good idea to have multiple different implementations!

[coding-horror]

oh my bad -- let's put the alternate back in if we can? I also think it's OK to have a few different implementations, but only if people feel that there's a good rationale for the different implementation, other than "mine is different"? There definitely should be comments in the alternate implementation explaining why it exists.
