Account Balances in Human Readable Format - Python

[litepresence]

get named balances returns an asset id without its human readable name....
and an amount - without the location of its decimal point!

this is kind of thing makes neckbeard itchy

Code: [Select]

["database","get_named_account_balances",["abc123", [] ]]
-----------------------------------------------------------
[{'asset_id': '1.3.0', 'amount': 12019967}, {'asset_id': '1.3.1382', 'amount': 100}, {'asset_id': '1.3.1578', 'amount': 100000000}, {'asset_id': '1.3.2419', 'amount': 500000}, {'asset_id': '1.3.2841', 'amount': 12000}, {'asset_id': '1.3.2931', 'amount': 10000}, {'asset_id': '1.3.3248', 'amount': 2580000}, {'asset_id': '1.3.3261', 'amount': 1000}, {'asset_id': '1.3.3279', 'amount': 10000}, {'asset_id': '1.3.3389', 'amount': 1000000000}, {'asset_id': '1.3.3431', 'amount': 1000}, {'asset_id': '1.3.3530', 'amount': 100000000}, {'asset_id': '1.3.3540', 'amount': 100000000}, {'asset_id': '1.3.3830', 'amount': '25000000000'}]

we can fix this... so get asset details

which is another api call and gives us "precision"; location of decimal, and the asset "symbol"; ie OPEN.BTC or BTS


but then we have to merge those dictionaries and they do not contain a common key; one has "asset_id" the other "id"

grrr

every call for what the asset is called and where its decimal point goes also contains bit of spam for every shitcoin donated to your account, on every bot tick, which brings in a huge page of asset banner ads like this silliness:

Code: [Select]

'{"main":"WARNING, DANGER, RED-ALERT, PANIC! PANIC! PANIC!\\n\\nYOU HAVE BEEN INFECTED,\\n\\nZOMBIES HAVE BEEN RELEASED! \\n\\nZombies are going to appear from nowhere & infest your portfolio,\\nSome zombies will come from your friends and family,\\nAND YES there are even some sickos out there that will want to buy Zombies too :s\\n\\n\\nThese VILE undead human corpses have risen, The Mission, BURN Zombies :)\\nHelp FILL THE POOL, Zombies are BURNED when there sent to the pool.\\n\\n\\nDisclaimer: NO REAL ZOMBIES WILL BE HURT IN THE CREATION OF THIS TOKEN ;)","short_name":"Zombies",

be thankful you're not on data plan!

nonetheless, hocus pocus account balances:
