If it doesn't slow down the distrib() implementation (i.e. only a sort() before returning), then perhaps the order of the results (if splitting on only one divider) should be assured, and selected with a keyword argument, defaulting to descending order. If the results of distrib() are unsorted, most applications using the method (again in the case of a single divider) will implement the same boilerplate to sort in ascending or descending order after each call. distrib_multiple() could be a separate method, to support a list of dividers mentioned in option 3. I think support for multiple dividers should be in there somehow, since it will be kind of tricky for most library users to implement a correct one on their own if they have a need. |

This is an easily understood example of why the distrib() method will be
necessary for Currency objects. It hadn't really sunk in until Raymond
mentioned pymoney's missing '/' operator on python-dev.
Something like the 1-into-3 example should always be prominently mentioned
in the documentation, as well as the docstring for distrib(). It should
probably also appear in some sort of exception message when a user tries
to use division with a Currency object.
It would also be useful to show for comparison a correct and efficient
distrib() for Decimal objects. If the recommendation is to convert to
Decimal when doing averages and other risky/lossy math, then it would be
good to show the cannonical Decimal distrib() function in convenient
location in the pymoney docs.
A distrib() function should not be added to stdlib decimal, obviously.

FWIW, I think that pymoney should consider a system of abstract multiple currencies if the goal is an eventual PEP and inclusion into the python stdlib. Hardcoding even relatively static ISO standards data into python stdlib seems like a backward compatibility headache in the making. It would seem like an add-on library will be necessary for any non-trivial application *using* pymoney currency features, so maybe the data should reside there, keeping the currency-neutral portion of pymoney-proper as small as possible. Perhaps an XML or YAML file format containing ISO and other concrete currency data could be shared among Python, Perl, PHP and Ruby. This shared data would be encoded into python source when pymoney(-addon) releases are made. |

Per my original suggestion, here are some mappings of ISO country code to ISO currency code. If anyone is planning pymoney's API design, they may provide a useful experimental tool, or a starting point for more refined mappings. I'm not the right person to comment on the utility of these types of mappings, I generally only work with local USD currency. I just thought I'd follow through on my initial idea and see what multicurrency people come up with after looking it over.

Per my original suggestion, here are some mappings of ISO country code to ISO currency code. If anyone is planning pymoney's API design, they may provide a useful experimental tool, or a starting point for more refined mappings. I'm not the right person to comment on the utility of these types of mappings, I generally only work with local USD currency. I just thought I'd follow through on my initial idea and see what multicurrency people come up with after looking it over. (also attached as file currencymappings.py, probably merge into pymoney_dat.py) # Map of ISO country codes to ISO currency codes # Only use official, currently published standards data # User applications may substitute own mapping for unusual # or time-dependent historical currency use per locale. # Initial data from: # http://europa.eu.int/comm/translation/currencies/entable1.htm # TODO:

People: News from the second day of the sprint. * Added and changed some attributes to the context: beautifiers for fancy formatted printing. * Changed the behaviour of str(): it now behaves like .formatted_str() without any arguments. To get the plain string of the currency's value, call Currency.value(). * Worked a lot cleaning the PEP, and corrected a lot of English mistakes. * Defined the behaviour of distrib() and implemented its test cases. For more references, see the updated PEP (please do the update, don't see it in the web because it take time to refresh). I want to thank specially to John Pinner, Rob Collins, Joe Wrigley and Didier Gouillaume for participating in the first Money sprint! .

OK. We was forgetting another issue here. Some people don't want the
distribution to be to the cent, dime, or whatever, but to a specific
value.
So, here is what I think will be pretty much the final version of
distrib(). Take a look to the examples, because my idea is to include
them as test cases. Please send other examples if you feel that is
good to test other corners of the problem.
----------------------
distrib(nparts=3DNone, proportions=3DNone, LSV=3DNone)
You can call distrib() with nparts XOR proportions. You can not callit
with both of them, neither with none of them. In any case, you also can
pass LSV.
If you call it with ``nparts`` (an integer or something that can be
int()'ed), the system will distribute the amount in that quantity of
parts, in the same proportion::
>>> Currency(1).distrib(nparts=3D3)
(Currency('0.33'), Currency('0.33'), Currency('0.34'))
>>>
>>> Currency(1).distrib(nparts=3D7)
(Currency('0.15'), Currency('0.14'), Currency('0.15'), Currency('0.14'),
Currency('0.14'), Currency('0.14'), Currency('0.14'))
If you call it with ``proportions`` (a tuple or something that can be
tuple()'d; and in each position of the tuple, a Decimal or something
that could be Decimal()'ed), the system will distribute the amount
regarding those proportions::
>>> Currency(1).distrib(proportions=3D[1,2])
[Currency("0.33"), Currency("0.67")]
>>>
>>> Currency(3).distrib(proportions=3D[2,1,3,3])
[Currency("0.66"), Currency("0.33"), Currency("1.01"), Currency("1.00")]
``LSV`` means "least significant value, and is the value to which the
system will aproximate the finals results. The default is
``10**(-dec_places)``, so if you have ``dec_places=3D2``, ``LSV`` will be
``0.01`` (which is what we used in the examples above). It must be a
Decimal or something that can be Decimal()'ed.
>>> Currency(1).distrib(nparts=3D3, LSV=3DDecimal("0.1"))
(Currency('0.40'), Currency('0.30'), Currency('0.30'))
>>>
>>> Currency(1).distrib(nparts=3D7, LSV=3D"0.05")
(Currency('0.15'), Currency('0.10'), Currency('0.15'), Currency('0.15'),
Currency('0.15'), Currency('0.15'), Currency('0.15'))
>>>
>>> Currency(1).distrib(proportions=3D[1,2], LSV=3D"0.2")
[Currency("0.40"), Currency("0.60")]
>>>
>>> Currency(3).distrib(proportions=3D[2,1,3,3], LSV=3DDecimal("0.15"))
[Currency("0.60"), Currency("0.30"), Currency("1.05"), Currency("1.05")]
This is needed (at least) in Sweden, where they're used to round to 50
cents when dealing with coins.

Heck, I'd even thought about combining 1) 3) and 2) somewhow but decided to not write about it ;-) (I can imagine a situation when I want to explicitly distribute the RS, but well, don't have a strong use-case actually, just an imagination).

Is it possible to have a combination of 1) and 3), with 1) being
a special case of 3)? That is, something along the lines of:
def distrib(self,nparts=None,proportions=None):
if nparts:
return self._real_distrib([1] * nparts)
return self._real_distrib(proportions)

We've been thinking yesterday how the Currency's distrib method should
work. We figured out three posibilities, but we're not be able to
choose a winner.
The basic idea is to distribute a Currency amount between different
parts, and being sure that you're not losing information (well, money,
;). But we saw three methods of doing it:
1. Returning the different currencies, splitting almost equally::
>>> Currency(1).distrib(3)
[Currency("0.33"), Currency("0.33"), Currency("0.34")]
>>> Currency(1).distrib(7)
[Currency("0.14"), Currency("0.14"), Currency("0.14"),
Currency("0.14"), Currency("0.15"), Currency("0.15"),
Currency("0.14")]
The order of the results is not assured. The difference between
max(results) and min(results) will be only one Less significant Digit.
2. Returning the almost exact part, with the rest (a kind of divmod()
but not to integers)::
>>> Currency(1).distrib(3)
(Currency("0.33"), Currency("0.01"))
>>> Currency(1).distrib(7)
(Currency("0.14"), Currency("0.02"))
If with the original value OV splited in N parts, it returns the
division and the rest (DV, RS), the following applies: DV * N + RS =3D
OV
3. Returning the different currencies, splitting differently::
>>> Currency(1).distrib([1,2])
[Currency("0.33"), Currency("0.67")]
>>> Currency(3).distrib([2,1,3,3])
[Currency("0.66"), Currency("0.33"), Currency("1.01"), Currency("1.00")=
]
The rest of the better-possible-division will be assigned to the
greatest(s) value(s) of the result.
What do you think?

People:
News from the first day of the sprint.
* We'll have two structures to keep the ISO currency information, the
first one will be:
{..., CurrCode : (CurrName, CurrNumber), ... }
from ISO 4217, and the second will be:
[..., (CountryCode, CountryName, CurrCode), ....]
from ISO 4217 and ISO 3166. John Pinner is actually building these two
structures (lot of work!), to be sure that this is OK.
* The curr_type default will be None, and it will not be mandatory to
configure it before start using the module.
* I created in CVS the test_money.py file, for the test cases, and
filled with a loooot of test cases.
* Put a create_currency() method in the context. The idea is to be
able to create a currency object directly from the context (using the
settings of that context and not the in-current-thread one).
* We defined the arithmetic operations in which it'll be allowed to
use Currency.
For more references, see the updated PEP (please do the update, don't
see it in the web because it take time to refresh).
Thanks!

I proposed originally that we have a structure, after parsing the ISO list = at http://www.iso.org/iso/en/prods-services/popstds/currencycodeslist.html?pri= ntable=3Dtrue like the following: {..., "ARS": ("ARGENTINA", "Argentine Peso", "032"), ... } Darek Suchojad noted that the first code, as different countrys have the exactly same currency, will be reapeated (which is a problem as we're using a dictionary), so he proposed: {..., "ARS": (("ARGENTINA", "Argentine Peso", "032"),), ... "USD": (("AMERICAN SAMOA", "US Dollar", "840"), ("BRITISH INDIAN OCEAN TERRITORY", "US Dollar", "840"), ... ), ... } Jeff Kowalczyk went a step further and suggested a new denomination for currencies, just to make them univocal, proposing the following structure (note how he flattened the structure). { ..., "AS-USD" : ("AMERICAN SAMOA", "US Dollar", "840"), "IO-USD" : ("BRITISH INDIAN OCEAN TERRITORY", "US Dollar", "840"), "US-USD" : ("UNITED STATES", "US Dollar", "840"), ..., } This brings the need of another structure, to map the original currency string to the invented ones, something like { ..., "USD":("AS-USD", "IO-USD", "US-USD"), ...} I have issues with the three structures proposed so far: 1. Mine: Clearly wrong! The currency string is repeated and we can not use it as a dictionary key. 2. Darek's: Don't like the not-flat property 3. Jeff's: Brings another layer of complexity: How do you choose (as a developer) and how do you predict (as user) the inserted two letters? Before chosing one, keeping proposing others, or discuss the actual ones, I think that we must focus in specifying what we need: 1. What information we want in the structure (or structures) 2. The standard source of that information 3. How we want to access that information Then, we could specify the structure/s that we'll use. So, start shooting! :) Regards, .

My personal opinion is that distrib() shoould not assure order. If you =
want
some order, order it, :p
What it should specify is that there won't be more than one LSN (less
significant number) between the min() and max() result of distrib.

Hm, did you really mean *random* here? Couldn't it be simply
implementation-dependent?
Perhaps something along the lines of:
distrib(amount, n[, sorted=False[, descending=False]])
Returns amount distributed into n parts as uniformly as possible.
Optional argument sorted indicates that the result should be sorted
(in ascending order by default). If sorted is given and not False,
and optional fourth argument descending is not False, the result
will be returned in descending order.
If sorted is False or omitted, the order of returned parts is
implementation-dependent.
Two caveats.
1. "as uniformly as possible" is vague, and while I can create some
testcases and I *know* that
>>> Currency(1).distrib(7)
should return
(Currency('0.15'), Currency('0.15'), Currency('0.14'),
Currency('0.14'), Currency('0.14'), Currency('0.14'),
Currency('0.14'))
I'm not sure how to express it in a manner that would leave no
doubts.
2. sorted is a builtin in 2.4

Both yes. It should say Decimal, and it should say ROUND_HALF_EVEN. =

"Rounded" means that you lost some digits, but those digits are zero. =
We
don't want an exception there:
>>> getcontext()
Context(prec=3D2, rounding=3DROUND_HALF_EVEN, Emin=3D-999999999, =
Emax=3D999999999,
capitals=3D1, flags=3D[Inexact, Rounded], traps=3D[Inexact, Overflow,
InvalidOperation, DivisionByZero])
>>> Decimal("5.0") + Decimal("5.0")
Decimal("10")
"Inexact" means that you lost some digits, and those digits matter:
>>> Decimal("5.1") + Decimal("5.2")
Traceback (most recent call last):
...
Inexact: Changed in rounding

The latter. And it must be defined if the bigger ones will be at the
beggining, at the end, or in random places in the structure (I'm not
choosing one of the options, but we must define which we'll choose and =
then
use it).

Hi,
I'm sending two files, which are an attempt to implement my current
understanding of the PEP. They're not finished (Currency.distrib
and DefaultContext.distrib methods are still to be written, I also need
to add more tests) and I'm not really sure that all of those
if context is None:
context = getcontext()
checks in almost all of Currency methods are needed, but the PEP clearly
says that "Definitely the idea is not to get a context per Currency value.".
Hm, I'm not sure, perhaps changing it to something like
def __add__(self, other, context=None):
""" Returns self + other.
"""
result = Currency(Decimal.__add__(self,other,context or getcontext()))
return context._round_to_dec_quant(result)
would be better?
I haven't also touched ISO-4217 and/or ISO-3166 tables at all, because
it's still unclear how should they look like.
I'm not an threading guy, so getcontext() and setcontext() methods
should be taken special care of (though I simply copy&pasted them
from decimal module).
Anyway, it's an attempt, I hope it will be useful, but feel free to
tell me it's a crappy code :-)

PS. I'm not submitting it to the sf.net patch tracker, should I?
