/usr/lib/test?
gene@lathe:/usr/lib/python2.6$ locate lib/test
/opt/libreoffice3.5/program/python-core-2.6.1/lib/idlelib/testcode.py
/usr/lib/pymodules/python2.6/launchpadlib/testing

/usr/lib/pymodules/python2.6/launchpadlib/tests/test_launchpad.pyc

There are half a dozen or more branches of the python tree that claim to 
have test things, but the universal answer is:

gene@lathe:/usr/lib/python2.6$ cd /usr/share/pyshared/numpy/lib/tests
gene@lathe:/usr/share/pyshared/numpy/lib/tests$ python -m test -uall
/usr/bin/python: test is a package and cannot be directly executed

I have installed several more python 'likely suspects' but have not changed 
a thing in the results.

python-daemon

[n8felton]

Hello all. Got a question for anyone out there that is willing to help. Looking 
to make a Python Daemon, Google searches lead me to 
http://pypi.python.org/pypi/python-daemon. My question is 2 part. 1) pip 
install python-daemon downloads version 1.6, but the site states that 1.5.5 is 
the latest version. Anyone know why this is? 2) With python-daemon having been 
last uploaded in 2010, is anyone aware if there is a better implementation for 
python daemons, or is this still considered current?

The author of the python-daemon package I believe is Ben Finney, 
who sometimes posts here.  Sadly, I think he is a member of a group 
of people here who say they filter out and ignore all messages posted 
from Google Groups (which would include yours and mine).  

If you get no other good answers here, you could try emailing him
directly at ben+pyt...@benfinney.id.au, which is the address on 
a recent post from him.

Or you could repost from other than GG if you don't mind being a 
tool of someone else's political agenda.

Trying to make a basic Python score counter in a game... will not count.

[Darrien Glasser]

Hey guys, I'm working on a Python rock paper scissors (lizard spock) game, and 
the beginning is complete. After I finished it, I thought, "You know what? I 
think I can make this even better, and add a score counter." And so I did.

The problem is that it doesn't seem to actually keep track of score. In fact it 
always keeps the score at 0 for both players. It's fully functional otherwise, 
but it's bothering me that I can't get it to work. 

Currently using Windows Python 32 bit v2.6.8

If you are keeping the score in 'winx 'and 'winy' then you are adding
one to the the values but not saving the results.

I think you want 

  winx = winx + 1

or more concisely,

  winx += 1

ANNOUNCE: pyparsing 1.5.7/2.0.0

[Paul McGuire]

With the release of version 2.0.0/1.5.7, pyparsing has now officially switched 
to Python 3.x support as its default installation environment. Python 2.x users 
can install the latest 1.5.7 release. (If you're using easy_install, do 
"easy_install pyparsing==1.5.7".)

I'm taking this opportunity to do some minor API tweaking too, renaming some 
operators and method names that I got wrong earlier (the old operators and 
methods are still there for now for compatibility, but they are deprecated to 
be removed in a future release):

- Added new operator '<<=', which will eventually replace '<<' for 
  storing the contents of a Forward(). '<<=' does not have the same
  operator precedence problems that '<<' does.

- 'operatorPrecedence' is being renamed 'infixNotation' as a better
  description of what this helper function creates. 'operatorPrecedence'
  is deprecated, and will be dropped entirely in a future release.

Several bug-fixes are included, plus several new examples, *and* an awesome 
example submitted by Luca DellOlio, for parsing ANTLR grammar definitions and 
implementing them with pyparsing objects.

I changed it so that it said winx += 1 etc. and it doesn't seem to save it. I 
also tried pulling the variables from the loop and making them global variables 
at the top.

The latter game me a traceback error when printing out the results. Any ideas?

Put this on top of your function:

global winx, winy


PS. Why did you put those delays in?  They are useless.

I figured it would be too much for the person playing the game. Getting 
attacked with lines of text and all. Although it is a pain developing with it.

And by the way, works perfectly now. Thanks for your help.

I was actually thinking of making a simple rock paper scissors game so I
went ahead and cobbled it together, using a design with a class and
generally a structured approach.. It keeps the scores, too, and you can
set both players to be AI, or one to be AI, or both to be humans:

https://github.com/pythonbyexample/PBE/blob/master/code/rockpaper.py

(it needs python3 but can be easily changed to work with python2.x)

That seems to be a problem with a certain class of users that have
adopted Pastebin, not a problem with the site itself.  What do you
hope to accomplish by boycotting Pastebin for actual code pastes?
Even if the site were to cease to exist tomorrow, what is to stop the

The comment by genbattle in the above link is an important one, I
think. The last time I used pastebin was for Pike code - does any
competing site have Pike support?

http://pastebin.com/UNTj642Y

I don't understand the idea behind the boycott. Are people worried
about the longevity of linked-to content, in the event that pastebin
should, as you say, cease to exist tomorrow? Or is it that some won't
click a pastebin link in case it's abusive? This isn't the sort of
abuse that can compromise your computer.

More courteous would be to NOT post an unsolicited email to a poster's
address gleaned (by someone else) from a mailing list, but to look for
contact details in the package itself. I haven't looked, so it may
well be that there are none, but if there's an official contact point
for the package, that would be a very good start.

If your post is swallowed by someone's twit filter, that probably
means that you're doing something twittish. Switching to direct mail

The contents of a twit filter can be just as good an indication
of a twit reader as a twit poster.

And as was pointed out the last time this subject came up, no,
other clients do not "have all the same benefits" [as GG].

Thanks for describing your system, and for using plain text in your message.

But the program you supplied is missing quite a bit, starting with the
imports.  And you say nothing at all about the error you get.

You should include a full traceback of whatever error you're getting,
along with information about how you got there.

I don't see any place there which is dealing with unicode, except for
the part which is commented out.  Hard to get an error on those lines.

Why Isn't Multiple Inheritance Automatic in Python?

[Nick M . Daly]

If you're short on time, the subject's all you need to read.  It seems
like it would always be the right thing to do, when the sub-class
specifically requests it.

It's very unlikely that multiple inheritance would go horribly wrong, as
long as classes adopt class-specific argument naming conventions.
However, ever since bug 1683368 [0] was fixed, it's now impossible to
cleanly create arbitrary inheritance trees.  The only reason I can't
just take anybody's code and plop it into my inheritance tree is because
Python demands that each class specifically opts in to MI though
mechanisms like the following:

1: class Foo(object):
2: def __init__(self, foo_bar, *args, **kwargs):
3: if Foo.__mro__[1] != object:
4: super().__init__(*args, **kwargs)
5: 
6: self.bar = foo_bar

Lines 3 and 4 are required because Foo might fall at the beginning or
the middle of in the inheritance tree: we can't know ahead of time.

>From my perspective, it'd be lovely if init methods implicitly accepted
*args and **kwargs while implicitly sending them off to the next class
in the MRO as the first call.  This would make the previous example
semantically equivalent to:

1: class Foo(object):
2: def __init__(self, foo_bar):
3: self.bar = foo_bar

Granted, that's probably too excessive and implicit for most folks to be
comfortable with, even though that's obviously the behavior a user
intends when they write code like:

1: class Baz(Foo, Bar):
2: def __init__(self):
3: super().__init__(foo_bar=1, bar_quote="Give me another!")

Fundamentally, I don't care if Foo or Bar explicitly handle being
composed into the inheritance tree.  They can be composed correctly
(they can do what the user is asking) in most obvious and simple cases,
and it'd be fine by me even if we threw errors in complex situations
(like overlapping argument names in init methods).

So, would it be a good idea to:

1. Undo the fix to bug 1683368, making multiple inheritance easier?

2. Make MI implicit, when subclasses try to use it?

Thanks for your time,
Nick

If anyone's interested, I've simplified the code further by making use
of my TextInput utility class; I've also made the game into a tutorial,
it can be found here:

http://lightbird.net/larks/rockpaper.html


The updated full code is really tiny (it requires utils.py which is
linked at the top of tutorial):


import sys
from random import choice as randchoice
from time import sleep

from utils import TextInput

players= 'XY'
ai_players = 'Y'
moves  = "rps"
wins   = ("rp", "sr", "ps")   # choice on the right side wins
status = "%5s %3d %5s %3d moves: %s %s"
pause_time = 0.3


class RockPaperScissors(object):
def run(self):
self.textinput = TextInput("(r|p|s)")
scores = [0, 0]

while True:
choice1, choice2 = (self.get_move(p) for p in players)

if choice1 != choice2:
winplayer = 1 if (choice1+choice2 in wins) else 0
scores[winplayer] += 1

print(status % (players[0], scores[0], players[1], 
scores[1], choice1, choice2))

sleep(pause_time)

def get_move(self, player):
if player in ai_players : return randchoice(moves)
else: return self.textinput.getval()


if __name__ == "__main__":
try  : RockPaperScissors().run()
except KeyboardInterrupt : pass

What happens when you do use UTF-8?

What do you mean, "use UTF-8"?


To learn about Unicode, start here:

http://www.joelonsoftware.com/articles/Unicode.html

If that helps you solve the problem, excellent. If not, please come back 
with your questions, but first read this:

http://www.sscce.org/

As given, we cannot answer your question easily, or at all, because we 
cannot run your code. It gives indentation errors, you don't tell us what 
modules you're using, and you haven't reduced the example down to the 
critical parts that demonstrate the failure.

All you've said is the exact same things that have already been said,
including that not everyone will see your post if you use Google
Groups. Why use something that unnecessarily restricts your audience,
when non-restrictive posting methods work just fine?

Anyway. This debate isn't going away; I have no strong side in it, I'm
just informing people of the fact that posting from GG will reduce
your potential response sources.

Hi,

If a tag is not already set you can create it with pyexiv2.

Example:
--
self.data = pyexiv2.ImageMetadata(img.jpg)
self.data.read()

tag = "Exif.Image.ImageWidth"
try:
self.data[tag].value = sizes[0]
except:
self.data[tag] = pyexiv2.ExifTag(tag, sizes[0])

How do you know? Between javascript and flash, just about any browser 
could be vulnerable to just about any website. You might implicitly trust 
Pastebin, but you can't possibly *know* that the site won't do bad 
things. It wouldn't be the first time that even a reputable website got 
hacked by somebody who used it to deploy malware.

But that's not why I dislike Pastebin. I argue against Pastebin because:

1) Longevity of the content. Your question is going to be around for 
much, much longer than your pastebin. People searching for help will 
click through to the pastebin and find the code is gone. It is really 
frustrating to (say) search for the solution to a problem, and find that 
the answer is given in an expired pastebin.


2) When you ask for help via email, you shouldn't assume that the people 
reading have access to the web. Perhaps they have email access, but all 
or part of the web is blocked to them. Perhaps they are reading email on 
a mobile device and don't mind paying to download a couple of KB of 
email, but draw the line at (potentially) hundreds of KB of a web page 
plus associated images, unnecessary javascript, web bugs, advertisements, 
etc. Or maybe they just don't want the context switch:

"I'm reading email right now, I'll click the link later..."

Email is a push technology. A pastebin is a pull technology. Whenever you 
require your audience to actively go and get content, you're cutting your 
audience by some fraction.

I am aware that it is irrational and silly, but for me it also has to do 
with a sense of fairness. I'm prepared to spend tens of minutes, or 
sometimes even an hour or more, solving somebody else's problem for no 
benefit except a sense of accomplishment. But ask me to click on a 
pastebin to find out what that question is, and I'm all "Why should I 
have to go out of my way to find out what your question is? You're asking 
me to do you a favour, and you're making me work to find out what the 
favour is??? Fuck you!"

But maybe that's just me :-)

I'm not saying "never use a paste bin". I think it probably makes lots of 
sense to use one in IRC, where it is inappropriate to paste more than a 
line or two of code at once, and the conversation is already ephemeral. 
But in a Usenet or email forum, I think it is almost always inappropriate 
to use paste bins. If your code is too large to paste directly in the 
body of your email, chances are it is too large to expect people to debug 
for you. But you can try adding it as an attachment (.py, not .doc), and 
only if you can't do that for some reason, then maybe a paste bin is 
appropriate.

I keep saying them because people like you keep saying (in
effect) that there is no difference in clients (in terms
of usability, convenience, setup effort and other factors
that vary on a person-by-person basis.)  I even wrote that 
above, right in the post you're replying to:
 
  >> no, other clients do not "have all the same benefits"

and yet you respond that other "posting methods work just fine"
Again, that may be true for you and your definition of "fine", 
and maybe even for many people but it is not true for everyone,

As you say, all this has been said before and if you need to 
refresh your memory, please see the list archives, the thread, 
"Simple Question regarding running .py program" around nov 14.

I didn't say that. The first twit filter I met was when my dad put
*his own* address into it, to avoid downloading the posts he'd sent
(on a modem, that was significant). And that was the most normal thing
to do, twitting yourself :)
