If you are on tight budget and depend so much on Python, I'm afraid you should either: a. grow your budget b. try another language For what I know, I wouldn't touch Arduino unless I really had to. The reason for this, I have been spoiled by machines, of which the smallest I wanted to touch had 3mb of ram. Arduinos, with their ram in kilobytes at best, don't qualify as interesting from my point of view. Also, I don't think they are so much attractive price-wise. I would rather buy myself a Beagle Bone, like this one: http://www.adafruit.com/products/513 http://beagleboard.org/bone However, if all that you want is flip some leds, this is huge overkill. For led flipping, Arduino sounds ok, just not with Python-as-we-like-it. Maybe some pseudoPython can be had on it. Myself, I would rather go with one of Arduino's supported languages or assembly. Or Forth. If you land among embedded systems, it's better to speak embeddish or you will feel uncomfortable.

Complete Python implementations (CPython, PyPy, IronPython, Jython) will have stronger requirements than minimal / incomplete implementations. As for CPython, it needs a C compiler, decent POSIX support, a 32-bit CPU at least, and realistically you won't do much with at least 8 MB RAM. We actually have a buildbot which regularly tests building and running of CPython on an ARM machine: http://www.python.org/dev/buildbot/all/buildslaves/warsaw-ubuntu-arm It's a Cortex A8 with 1GB RAM, though, so I don't know if it's in your range (but 1GB is not needed at all, except that it's nice when running the full regression test suite).

It sounds like I can run one on 300mA @ 5V. For my application, I'll have about 10 A-h available at 12V (motorcycle battery). Assuming (mumble, cough, cough) 75% down-conversion efficiency, 120 W-h @ 12V gets me 90 W-h @ 5V, which is 18 A-h, or 60 hours of operation. Of course, I've got to run some other stuff too, but I don't think the Raspberry Pi is going to blow my power budget. In any case, the dirt-cheap price makes it really attractive.

Early orders have been filled, more are being filled, but there is a huge backlong and therefore a long wait if you waited til now to order. If you want one right away, at least as of a week or so ago they were going for $200-ish on ebay. The Raspberry Pi is not really appropriate for a low powered portable application anyway, because of relatively high power requirements compared to an 8 bitter without all that media playback stuff. The Beaglebone (www.beagleboard.org) is slightly higher end than the RPi and runs Python nicely, though it faces the same issues. I think a microcontroller (AVR, MSP430 etc) is a better fit for the OP's application than anything big enough to run Python.

Rasberry Pi is available, some have arrived, mine will arrive on Monday or Tuesday (I'm talking about UK here). I think getting python to run on an arduino device would be quite a lot of effort even if it's possible.

The Arduino uses an 8-bit micro-controller, so probably not. (The ARM emulator based port of Linux probably doesn't meet your performance requirements.) I think you may need to either wait for the Rasberry Pi to become generally available or increase your budget. You should also consider whether any of these devices have Python bindings to interface with their GPIO pins. If not you'll probably have to end up writing some C code anyways.

No. YOu want a 32-bit platform with an OS and perhaps 1 meg of memory. And by the time you port Python to it unless it's there already, you may as well have just written your application in C. If you want something even cheaper than an Arduino, look at the TI Launchpad. But you can't program that in Python either. There is a standalone interactive Forth for it, if that's of any interest: http://www.somersetweb.com/4E4th/EN.html There are some fairly cheap ARM boards around that could run Python, but they will be battery hungry compared to a Launchpad or Arduino, and again, may not be worth the porting hassle if there's not an already-done Python port. Lua might be another scripting language of interest (www.lua.org). Sort of the same idea as Python, not quite as nice, but smaller and easier to embed. I think it wants around 50-100k of ram, still way out of the Arduino range. -- http://mail.python.org/mailman/listinfo/python-list

By some measures, it's an expensive way to get mail access, but I'd much rather give Panix $100 than take advantage of any of the free mail services who does who-knows-what with my mail. Not to mention that I get access to such private newsgroups as panix.nytel.abuse. -- http://mail.python.org/mailman/listinfo/python-list
Smallest/cheapest possible Python platform?
What's the smallest/cheapest/lowest-power hardware platform I can run Python on today? I'm looking for something to use as a hardware controller in a battery-powered device and want to avoid writing in C for this project. Performance requirements are minimal. I need to monitor a few switches, control a couple of LEDs and relays, and keep time over about a 30 minute period to 1/10th second accuracy. Nice-to-have (but not essential) would be a speech synthesizer with a vocabulary of maybe 50 words. The Rasberry Pi certainly looks attractive, but isn't quite available today. Can you run Python on an Arduino? Things like http://www.embeddedarm.com/products/board-detail.php?product=TS-7250 are more than I need, and the $129 price probably busts my budget. -- http://mail.python.org/mailman/listinfo/python-list

You need a GUI framework. My suggestion would be to install PySide, which is a QT wrapper that includes a Webkit component. The other option is to use PyObjC to build a Cocoa GUI but then you're restricted to Mac OS X only. -- http://mail.python.org/mailman/listinfo/python-list

Automatically caching computationally intensive variable values?
I am working with a few corpora included in nltk-data with NTLK
(http://nltk.org/) to figure out certain algorithms.
So my code would generally be something of the style:
import re, nltk, random
from nltk.corpus import reuters
def find_test_and_train_data():
return [fileid for fileid in reuters.fileids() if
re.match(r"^training/", fileid)], [fileid for fileid in
reuters.fileids() if re.match(r"^test/", fileid)]
def generate_random_data(train_and_test_fileids):
random.seed(348) ; random.shuffle(train_and_test_fileids[0])
return train_and_test_fileids[0][2000:],
train_and_test_fileids[0][:2000]
def fileid_words(fileid):
return [word.lower() for line in reuters.words(fileid) for word
in
line.split() if re.match('^[A-Za-z]+$', word)]
if __name__ == '__main__':
train_fileids, dev_fileids =
generate_random_data(find_test_and_train_data())
train_data=fileid_words(train_fileids)
dev_data=fileid_words(dev_fileids)
So if I run it into an interactive interpreter I can then perform
tasks on `train_data`, `dev_data` and their corresponding fileids
without repopulating the variables (a very time consuming task, e.g.:
this takes 7 minutes to run each time).
However, I want to be able to write it into a .py file so that I can
save statistically interesting algorithms.
I could do this by double-typing, e.g.: when I get a function working
in the interpreter I then copy+paste it into the .py file, but this is
quite inefficient and I lose out on my IDEs' features.
Are there any IDEs or Python modules which can automatically keep the
Python script running in memory, or store the value of a variable—such
as `test_data`—in a db?
Thanks for all suggestions

What I'm doing myself on Windows is deciding which version of Python I want to be the default, and install that from the msi normally (including "register extensions" options). I then proceed to add its install location to my %PATH%. After which I install additional Python versions but *without* selecting "register extensions" otherwise they will overwrite the registry associations. I have about 5 different versions coexisting peacefully in c:\python26 c:\python27 c:\python27-64, c:\python32 and c:\python33 (with python27 being the default and only c:\python27 added to %PATH%) In the IDE I'm using (PyCharm) you can trivially switch the Python version it will use for your project. > Thank you! > > Uli > > PS: Dear lazyweb, is there any way to teach VC8 some syntax highlighting > for Python? http://pytools.codeplex.com/ perhaps?
