Prices: Python price handling for humans

Money:

from prices import Money
a = Money(10, \'USD\')
a += Money(20, \'USD\')
a.value
# Decimal(\'30\')
a = a.quantize()
a.value
# Decimal(\'30.00\')
a = Money(\'5.00\', \'JPY\')
a.quantize()
a.value
# Decimal(\'5\')

Taxed money:

from prices import Money, TaxedMoney
p = TaxedMoney(net=Money(20, \'EUR\'), gross=Money(30, \'EUR\'))
p.net
# Money(\'20\', \'EUR\')
p.gross
# Money(\'30\', \'EUR\')
p.tax
# Money(\'10\', \'EUR\')
p = p.quantize()
p.net
# Money(\'20.00\', \'EUR\')

Taxed ranges:

from prices import Money, TaxedMoney, TaxedMoneyRange
price1 = TaxedMoney(Money(1, \'USD\'), Money(1, \'USD\'))
price2 = TaxedMoney(Money(10, \'USD\'), Money(10, \'USD\'))
pr = TaxedMoneyRange(price1, price2)
pr.min_price
# TaxedMoney(net=Money(\'1\', \'USD\'), gross=Money(\'1\', \'USD\'))
pr.max_price
# TaxedMoney(net=Money(\'10\', \'USD\'), gross=Money(\'10\', \'USD\'))
price3 = TaxedMoney(net=Money(5, \'USD\'), gross=Money(5, \'USD\'))
price3 in pr
# True
pr = pr.quantize()
pr.min_price.net
# Money(\'1.00\', \'USD\')

Taxes:

from decimal import Decimal
from prices import Money, TaxedMoney, TaxedMoneyRange, flat_tax
p = TaxedMoney(Money(\'1.99\', \'GBP\'), Money(\'1.99\', \'GBP\'))
p = flat_tax(p, Decimal(\'0.23\'))
p = p.quantize()
p.gross
# Money(\'2.45\', \'GBP\')

While protecting you from all sorts of mistakes:

from prices import Money
Money(10, \'USD\') < Money(15, \'GBP\')
# ValueError: Cannot compare amounts in \'USD\' and \'GBP\'

from prices import Money, TaxedMoney
price1 = TaxedMoney(Money(5, \'BTC\'), Money(5, \'BTC\'))
price2 = TaxedMoney(Money(7, \'INR\'), Money(7, \'INR\'))
price1 + price2
# ValueError: Cannot add amount in \'BTC\' to \'INR\'
