Interesting.... a Python altcoin would be odd. There are some things I think would be hard to convert from C++ to Python though.
Hi! Thanks for your answer 
Yes, of course it will be a hardwork, but as I said, well documented can be a good tool for learning!
Also, the idea is inplement the core funcrions first. I don't want to create another monster code.
Can be something similar to Arionum coin (www.arionum.con) but in Python instead PHP...
