mcpython -
based on python for minecraft server by http://pinet.rouviere.free.fr/index.html
based on the package mcpi developed by Martin O'Lannon @martinohanlon for the Raspberry Juice Mod, modified by @sprouviere, and further modified by @lasteamlab.
In the mcpi and raspberry juice setup you used block.BLOCKTYPE.id to reference blocks.
With this setup you will use "BLOCKNAME" from this list:
