You can use the account_info method to retrieve all account information including assets created by the account. The assets created lives under "thisassettotal" in the account info json.
from algosdk import algod
# set up client using your credentials
algod_client = algod.AlgodClient("<algod_token>", "<algod_address>")
# retrieve account info
account_info = algod_client.account_info("<ADDRESS>")
# retrieve all assets created by this account
assets_created = account_info.get("thisassettotal")
# this returns a dictionary keyed by the asset ID. Asset IDs are ordered - the higher the ID the more recently it was created - so if you want the latest created asset, pick the max ID.
last_created_asset = max([int(id) for id in assets_created.keys()])
# get asset info for latest created asset
asset_info = assets_created.get(str(last_created_asset))
print(asset_info)
I’ve added a note to add this to the docs as well.
