[ANN]: Python module to distribute computations for parallel execution
Hello, I would like to announce dispy (http://dispy.sourceforge.net), a python framework for distributing computations for parallel execution to processors/cores on single node to many nodes over the network. The computations can be python functions or programs. If there are any dependencies, such as other python functions, modules, classes, objects or files, they are also distributed as well. The results of each computation, output, error messages and exception trace, if any, are made available to client program for further processing. Popular map/reduce style programs can be easily developed and deployed with dispy. There is also an implementation of dispy, called discopy, that uses asynchronous I/O and coroutines, so that discopy will scale efficiently for large number of network connections (right now this is a bit academic, until it has been tested with such setups). The framework with asynchronous I/O and coroutines, called asyncoro, is independent of dispy - discopy is an implementation of dispy using asyncoro. Others may find asyncoro itself useful. Salient features of dispy/discopy are: * Computations (python functions or standalone programs) and its dependencies (files, python functions, classes, modules) are distributed automatically. * Computation nodes can be anywhere on the network (local or remote). For security, either simple hash based authentication or SSL encryption can be used. * A computation may specify which nodes are allowed to execute it (for now, using simple patterns of IP addresses). * After each execution is finished, the results of execution, output, errors and exception trace are made available for further processing. * If callback function is provided, dispy executes that function when a job is finished; this feature is useful for further processing of job results. * Nodes may become available dynamically: dispy will schedule jobs whenever a node is available and computations can use that node. * Client-side and server-side fault recovery are supported: If user program (client) terminates unexpectedly (e.g., due to uncaught exception), the nodes continue to execute scheduled jobs. If client-side fault recover option is used when creating a cluster, the results of the scheduled (but unfinished at the time of crash) jobs for that cluster can be easily retrieved later. If a computation is marked re-entrant (with 'resubmit=True' option) when a cluster is created and a node (server) executing jobs for that computation fails, dispy automatically resubmits those jobs to other available nodes. * In optimization problems it is useful for computations to send (successive) provisional results back to the client, so it can, for example, terminate computations. If computations are python functions, they can use 'dispy_provisional_result' function for this purpose. * dispy can be used in a single process to use all the nodes exclusively (with JobCluster - simpler to use) or in multiple processes simultaneously sharing the nodes (with ShareJobCluster and dispyscheduler). dispy works with python 2.7. It has been tested on Linux, Mac OS X and known to work with Windows. discopy has been tested on Linux and Mac OS X. I am not subscribed to the list, so please Cc me if you have comments.

Re: Automatic Type Conversion to String
Could it be that you missed the fact that strings are immutable? That means that you can't change the content of the object once it is initialized. In particular, it means that you e.g. have to override __new__ instead of __init__, because the content is already fixed when the latter is called. Uli Yes, that's what I missed, and it explains why I found examples of str inheritance using __new__. I think this might end up being a puzzle I poke at for awhile. Also, I discovered that the attempt to create a Path class goes back to 2006, where it created a lot of discussion and was finally shelved: http://www.python.org/dev/peps/pep-0355/ A significant part of the problem seems to be that there was no inheritance from str at the time, so maybe a lot of the issues they ran into could be solved now. -- http://mail.python.org/mailman/listinfo/python-list

Python to Combine Multiple Excel Worksheets into One Worksheet
Hello, I have one single Excel file with many separate worksheets, and for work I need to combine all these separate worksheets into one single worksheet (I am not worried about formatting, as the format is the same in each sheet, nor am I worried about Excel's row limit). Essentially, I am looking for a way to append the data in one sheet to the bottom of the sheet that proceeds it. What would be the best way to do this, and how would I go about doing it? Can it be done simply with the xlwt, xlrd, and xutils modules, or (as I was thinking) do I need to convert the sheets to separate csv files, then append the separate csv files, and then write the completed file back into .xls format? Or perhaps something else? As I am really only a Python beginner, any and all help is very much appreciated. Thank you in advance!! -- http://mail.python.org/mailman/listinfo/python-list

Welcome to the mailing list.
Some fundamentals, please:
1) give python version os
2) copy/paste the code, don't retype it. You have lots of typos which
would cause syntax errors, not xxx has no attribute yyy. And please
don't use 1 column indents; they're illegible. 4 spaces is a good
number, recommended in a large number of places, including pep8.
3) copy/paste the whole error, including traceback. Without it in this
case, we're forced to guess where the problem might be, and that must be
somewhere else in the program, since the only write() attribute you've
quoted here are on f.write() calls, and f is only set to a file object,
not a string object. There are lots of ways in the code you don't show,
where you might confuse the system, such as redefining open.
Now to your questions:
A) Since you don't show n, it could very well be 0 or negative, in which
case the inner loop would never execute.
B) Since you don't have correct indentation, it's possible the actual
program closes the file inside the inner loop, in which case it might
execute just once, then get an exception. not the one you quote, but
whatever.
C) Depending on how you run this program, perhaps the file isn't getting
flushed when you get your error, so you just think the output didn't happen.
D) BTW, i don't see any prints, but perhaps that's a minor point. You
might think of file.write() as printing to a file. Sort of.

Stand-Alone Python Executable Skeletons
I've recently been looking into different options to package python code into stand-alone executables, with tools like Py2EXE and PyInstaller, but I'm left feeling a little lost.

It feels like they could be a lot simpler, or that I could put in some preliminary work to make it easier for my needs in the long run. I'm hoping someone can help me pick the best option. What I would love to do (or know if it is possible) is have a set of executables, for Linux, Windows, and OS X, with a Zip archive appended to the end of them. I know the zip archive at the end of an executable works with EXE and ELF binaries, but does it work for whatever OSX uses (I have no mac machines, currently)? I'd like to build these three empty stand-alone python executables, setup such that they'll run any main.py sitting at the top level of the archive. After this, building for all three platforms would just be a matter of copying the empty versions and dumping the project into it. I'm leaning on doing this with PyInstaller being the easiest. Am I headed in the right direction? Ideally, these empty stand-alones could be distributed for use by others without any tools required to use them other than a zip utility. -- Read my blog!

You could also eliminate some repetition in the deal method by putting
the suit lists in a local dict:
suits = {'S': self.spades, 'H': self.hearts,
'D': self.diamonds, 'C': self.clubs}
for card in cards:
suits[DECK[card][SUIT]].append(DECK[card][RANK])
Another comment I had at first was that instead of creating the pack
list, which is just a list of indexes into DECK, you could shuffle and
deal the DECK list directly. But then I realized that the indirection
allows you to easily sort the cards in the desired order, so that
should be left alone.

code quality, adherence to standards and so forth. The code is
at:
All the .append()s seem a little unpythonic to me. I'd just set
it up with
CONDITIONS = [
[...],
...
]
And since you're not modifying it, I'd even use tuples (or named
tuples):
CONDITIONS = (
(Dealer North, Neither vulnerable),
...
)
I'd also take advantage of iterable-unpacking to do something
like the following in your Player.deal() method:
for card in cards:
suit, rank = DECK[card]
{
'S': self.spades,
'D': self.diamonds,
'C': self.clubs,
'H': self.hearts,
}[suit].append(rank)
(that fixed dictionary might even be hoisted out for reuse
elsewhere).
Additionally, if you import this as a module rather than running
it directly, there's no north, south, ... in your module
namespace (they're only defined in the if __name__ ... section)
so it will fail.
There are some other structural decisions that I might reconsider
too:
- just shuffling the deck, rather than shuffling indexes into
that deck
- there seems to be a lot of redundancy in the drawing code, but
I'm not sure how I'd reduce that
- assigning to internal rank-named lists seems a little redundant
to me. In my (non-bridge) card-playing history, and tinkering
with small programs like this to simulate card-games, I usually
just give a player the cards and then leave the sifting/sorting
to the display algorithm
- I see Ian's email came in as I was typing this and agree with
his method of defining CONDITIONS with the caveat that it doesn't
keep the same order as yours (I seem to recall bridge had some
odd rules about that order)

Looks pretty nice overall. To reduce repetition, I would have
constructed the CONDITIONS list by iteration like you did the DECK list,
something like:
DEALERS = [Dealer North, Dealer East, Dealer South, Dealer West]
VULNERABILITIES = [
Neither vulnerable, North-South vulnerable,
East-West vulnerable, Both vulnerable,
]
CONDITIONS = [(d, v) for d in DEALERS for v in VULNERABILITIES]
You could also eliminate some repetition in the deal method by putting
the suit lists in a local dict:
suits = {'S': self.spades, 'H': self.hearts,
'D': self.diamonds, 'C': self.clubs}
for card in cards:
suits[DECK[card][SUIT]].append(DECK[card][RANK])
Another comment I had at first was that instead of creating the pack
list, which is just a list of indexes into DECK, you could shuffle and
deal the DECK list directly. But then I realized that the indirection
allows you to easily sort the cards in the desired order, so that should
be left alone.
Thank you very much indeed, Ian.
Your second suggestion has opened my eyes; it had not even occurred to me
that the value element of a dictionary entry could be a list. Just
shows me how much I have to learn! Isn't Python great?
As to your first suggestion though, I am having some difficulty. Note
that the vulnerability rotates; i.e. CONDITIONS[4] is not the same as
CONDITIONS[0].
Is there a better way of doing it than a simple list.append()?
Thanks again.

Re: format a measurement result and its error in scientific way
On Wed, Feb 15, 2012 at 5:18 PM, Daniel Fetchinson
fetchin...@googlemail.com wrote:
Hi folks, often times in science one expresses a value (say
1.03789291) and its error (say 0.00089) in a short way by parentheses
like so: 1.0379(9)
One can vary things a bit, but let's take the simplest case when we
only keep 1 digit of the error (and round it of course) and round the
value correspondingly. I've been searching around for a simple
function that would take 2 float arguments and would return a string
but didn't find anything although something tells me it's been done a
gazillion times.
What would be the simplest such function?
Well, this basically works:
def format_error(value, error):
... precision = int(math.floor(math.log(error, 10)))
... format = %%.%df(%%d) % max(-precision, 0)
... return format % (round(value, -precision),
... int(round(error / 10 ** precision)))
...
format_error(1.03789291, 0.00089)
'1.0379(9)'
Note that math.floor(math.log(error, 10)) may return the wrong
decimal precision due to binary floating point rounding error, which
could produce some strange results:
format_error(10378929, 1000)
'10378900(10)'
So you'll probably want to use decimals instead:
def format_error(value, error):
value = decimal.Decimal(value)
error = decimal.Decimal(error)
value_scale = value.log10().to_integral(decimal.ROUND_FLOOR)
error_scale = error.log10().to_integral(decimal.ROUND_FLOOR)
precision = value_scale - error_scale
if error_scale 0:
format = %%.%dE % max(precision, 0)
else:
format = %%.%dG % (max(precision, 0) + 1)
value_str = format % value.quantize(decimal.Decimal(10) ** error_scale)
error_str = '(%d)' % error.scaleb(-error_scale).to_integral()
if 'E' in value_str:
index = value_str.index('E')
return value_str[:index] + error_str + value_str[index:]
else:
return value_str + error_str
format_error(1.03789291, 0.00089)
'1.0379(9)'
format_error(103789291, 1000)
'1.03789(1)E+08'
I haven't tested this thoroughly, so use at your own risk. :-)

Ian

[issue13598] string.Formatter doesn't support empty curly braces {}
Nick Coghlan ncogh...@gmail.com added the comment: One potential problem with the simple approach to fixing this is that up until now, string.Formatter has been thread safe. Because all the formatting state was held in local variables and passed around as method arguments, there was no state on the instance object to protect. Now, this only applies if you start using the new feature, but it should be noted in the documentation and What's New that you need to limit yourself to accessing each formatter instance from a single thread. It's also enough for me to say no, not in a maintenance release. Adding two attributes also seems unnecessary, and the pre-increment looks strange. Why not: In __init__: auto_field_count = 0 Then as the auto numbering checking, something like: auto_field_count = self.auto_field_count if field_name: if auto_field_count 0: # Can't switch auto - manual auto_field_count = -1 elif auto_field_count 0: # Can't switch manual - auto else: field_name = str(auto_field_count) self.auto_field_count += 1 (Alternatively, I'd ask the question: why do we prevent mixing manual numbering and explicit numbering anyway?
