Intro

IOTA is a revolutionary new transactional settlement and data integrity layer for the Internet of Things. It’s based on a new distributed ledger architecture, the Tangle, which overcomes the inefficiencies of current Blockchain designs and introduces a new way of reaching consensus in a decentralized peer-to-peer system. For the first time ever, through IOTA people can transfer money without any fees. This means that even infinitesimally small nanopayments can be made through IOTA. - From the docs

Sounds pretty cool! And I think it has potential to overcome some existing blockchain issues. I wanted to try out some development using Python and IOTA Python. It took a bit of work getting started but once you know the steps it's pretty easy so I thought I'd share what I did.

Setup Dev Environment

It's always good practise to develop using a virtual environment so I started in a clean dir and ran:

Question	BOLT	GRID
Is the token tied to a product usage, i.e. does it give the user exclusive access to it, or provide interaction rights to the product?	Yes, Provides access to Grid+ energy.	Yes, 1 GRID token = 500 kWh at the wholesale price.
Does the token grant a governance action, like voting on a consensus related or other decision-making factor?	No	No
Does the token enable the user to contribute to a value-adding action for the network or market that is being built?	Yes, Selling generated electricity on a p2p network.	No
Does the token grant an ownership of sorts, whether it is real or a proxy to a value?	Yes, Ownership of energy.	Yes, Ownership of wholesale energy.
Does the token result in a monetizable reward based on an action by the user (active work)?	Yes, Any revenue earned by a customer from selling electricity is earned in BOLT tokens instead of fiat and is stored on the Agent.	No
Does the token grant

Question	STORM
Is the token tied to a product usage, i.e. does it give the user exclusive access to it, or provide interaction rights to the product?	Yes, 'Makers' are required to pay for posts in STORM tokens
Does the token grant a governance action, like voting on a consensus related or other decision-making factor?	No
Does the token enable the user to contribute to a value-adding action for the network or market that is being built?	Yes. Bolts can be used to boost Players access to tasks.
Does the token grant an ownership of sorts, whether it is real or a proxy to a value?	No
Does the token result in a monetizable reward based on an action by the user (active work)?
