accounting module

abcFinance is an implementation of an double entry book keeping system

Initialize the accounting system with, the name of the residual_account:

accounts = AccountingSystem('equity')

Create stock and flow account:

accounts.make_stock_account([‘cash’, ‘claims’]) accounts.make_flow_account([‘expenditure’])

In order to book give a list of credit and debit tuples. Each tuple should be an account and a value:

accounts.book(
    debit=[('cash', 50), ('claims', 50)],
    credit=[('equity', 100)])

get balance gives you the balance of an account:

assert accounts[‘cash’].get_balance() == (s.DEBIT, 50)

Balance sheet

accounts.book(debit=[(‘expenditure’, 20)], credit=[(‘cash’, 20)])

assert accounts.get_total_assets() == 80, accounts.get_total_assets()

accounts.print_profit_and_loss() print(‘–’) accounts.make_end_of_period()

accounts.print_profit_and_loss()

accounts.print_balance_sheet()

assert accounts[‘equity’].get_balance() == (s.CREDIT, 80)
