Some more work on an Ethereum (classic) accounting tool

So, I've hacked some more on the tool I'm building for accounting purposes.

I guess since the last time I've posted on it, there are mainly two things I've been working on, one is valuation of crypto currency, the other is correctness of generated CSVs.

I've followed a simple principle when it comes to valuation of the crypto currency; and that is, first in, first out. Other options could be first in, highest value out, or first in, lowest value out.

It looks like in Norway, there is also the option of first in, whichever you want out; meaning you can receive crypto, and for tax purposes, choose which crypto currency you sell first. Which could be useful for tax purposes, to increase or decrease the tax owed due to dealings with crypto currency.

But it's a bit to keep track of, and I think I've gotten most of it done.

Another part however, is making sure the values in the CSV / Spreadsheet are correct, and I noticed that somewhere along the line of transactions, the account balance was off, compared to the state in etherscan.io for example. So I started looking, and figured out that it was due to a transaction that was registered, but didn't complete, because it ran out of gas. The max fee to complete the transaction was too low.

But as the transaction is still registered, you still have to pay the gas fee, so for that transaction, the value of the crypto transferred to another account is zero, and the gas fee still needs to be deducted.

You can see more about this on the go-ethereum issue tracker

https://github.com/ethereum/go-ethereum/issues/24768

there is also information in the commit:

https://github.com/morphex/ethereum-classic-taxman/commit/1a...

I think this shows, really well, how good Python integrates with the command line, and how easy it is to get something done in Python. A handful of changed lines, and it is possible to manually exclude a set of comma-separated transactions.

Of course this is also due to knowledge of how Python works, but yes, a great scripting and prototyping language Python is.
