Package: ud-py-moneyed
Customized fork ofhttp://github.com/limist/py-moneyedwhich adds
ability to extend the coreMoneyclass.The need to represent instances of money frequently arises in software
development, particularly any financial/economics software.  To
address that need, the py-moneyed package provides the classes of
Money and Currency, at a level more useful than just using Python’s
Decimal class, or ($DEITY forbid) the float primitive.  The package is
meant to be stand-alone and easy to either use directly, or subclass
further.  py-moneyed is BSD-licensed.Some of the py-moneyed code was first derived from python-money
available via this URL:http://code.google.com/p/python-money/Because
that Google Code version has been inactive since May 2008, I forked it
and modified it for my needs in 2010. Compared to python-money, major
changes here in py-moneyed include separating it from Django usage,
tightening types handling in operators, a complete suite of unit
tests, PEP8 adherence, providing a setup.py, and local currency
formatting/display.UsageOn to the code! The Money class is instantiated with:An amount which can be of type int, string, float, or Decimal.
It will be converted to a Decimal internally. Therefore, it is best
to avoid float objects, since they do not convert losslessly
to Decimal.A currency, which usually is specified by the three-capital-letters
ISO currency code, e.g. USD, EUR, CNY, and so on.
It will be converted to a Currency object.For example,frommoneyedimportMoneysale_price_today=Money(amount='99.99',currency='USD')You then use Money instances as a normal number. The Money class provides
operators with type checking, matching currency checking, and sensible
dimensional behavior, e.g. you cannot multiply two Money instances, nor can you
add a Money instance to a non-Money number; dividing a Money instance by another
results in a Decimal value, etc.The Currency class is provided with a complete dictionary of ISO 4217
currencies data, each key (e.g. ‘USD’) mapping to a Currency instance
with ISO numeric code, canonical name in English, and countries using
the currency.  Thanks to the python-money developers for their
(possibly tedious) data-entry of the ISO codes!All of these are available as pre-built Currency objects in themoneyedmodule.You can also pass in the arguments to Money as positional arguments.
So you can also write:>>>frommoneyedimportMoney,USD>>>price=Money('19.50',USD)>>>price19USD>>>price.amountDecimal('19.50')>>>price.currencyUSD>>>price.currency.code'USD'FormattingYou can print Money object as follows:>>>frommoneyed.localizationimportformat_money>>>format_money(Money(10,USD),locale='en_US')'$10.00'TestingUnit-tests have been provided, and can be run withtox(recommended)
or just py.test.If you don’t have tox installed on your system, it’s a modern Python
tool to automate running tests and deployment; install it to your
global Python environment with:sudo pip install toxThen you can activate a virtualenv (any will do - by design tox will
not run from your globally-installed python), cd to the py-moneyed
source directory then run the tests at the shell:cd where/py-moneyed-source/is
toxIf you do not have all versions of Python that are used in testing,
you can usepyenv. After installing pyenv, install the additional
pluginpyenv-implict.The py-moneyed package has been tested with Python 2.6, 2.7, 3.2, 3.3
and PyPy 2.1.FutureFuture versions of py-moneyed may provide currency conversions or
other capabilities, dependent on feedback and usage.
