Encode HTML CDATA name token
Hi,
ID and NAME tokens must begin with a letter ([A-Za-z]) and may be
followed by any number of letters, digits ([0-9]), hyphens ("-"),
underscores ("_"), colons (":"), and periods ("."). [1]
Is there a encoder / decoder in Python that can convert arbitrary text
to and from this encoding in an readable manner?
base64 is not readable:
In [31]: base64.encodestring("/TEST")
Out[31]: 'L1RFU1Q=\n'
quopri does not encode for example "/".
In [25]: quopri.encodestring("/test")
Out[25]: '/test'
Anything else?

If you actually wanna fold the T, you need to snip off the cap and
reverse it, per this diagram:

120 of them, 60 folded left, 60 folded right, all of volume 1/24, make
the volume 5 rhombic triacontahedron.
http://www.rwgrayprojects.com/synergetics/s09/figs/f86419.html
If you blow up the volume by 3/2, to 7.5, the radius becomes phi /
sqrt(2) -- what we're showing with Decimals.
The reason this seems unfamiliar is the unit of volume is the
tetrahedron formed by any four equi-radiused balls in inter-tangency.

Re: [Edu-sig] teaching python using turtle module
Hello Brian,
I think the most natural use of the if statement (using turtle
graphics) occurs in recursive functions drawing trees,
fractals and the like. This is well known from Logo, where
recursion is the canonical way of doing repetitions. (But
note, that Logo has tail recursion optimizaton!)
If you are not yet ready to use recursion with your students,
probably many of the problems coming to your mind that need
the examination of conditions can be solved better by using
a conditional loop (i. e. a while -loop in Python) than by
using mere if statements.
That is not the case however, if you have to perform actions in
the body of a loop, that depend on the current situation.
I did a quick search in my repository of examples and found
a fairly short and simple script that demonstrates, what I mean:
a drunken turtle collecting coins (or whatever) on its random walk.
# Python script using turtle graphics
from turtle import Screen, Turtle
from random import randint
s = Screen()
s.setup(560,560)
s.title("A drunken turtle collecting ...")
s.tracer(False)
writer = Turtle(visible=False)
writer.penup()
writer.goto(0, -275)
coins = []
for i in range(-4,5):
for j in range(-4, 5):
if i == j == 0:
continue
c = Turtle(shape="circle")
c.color("", "orange")
c.shapesize(0.5)
c.goto(40*i, 40*j)
coins.append(c)
s.tracer(True)
DRUNKENNESS = 45
t = Turtle(shape="turtle")
t.color("black","")
points = 0
while abs(t.xcor()) < 200 and abs(t.ycor()) < 200:
t.forward(5)
t.right(randint(-DRUNKENNESS, DRUNKENNESS))
found = None
for c in coins:
if t.distance(c) < 10:
found = c
break
if found:
found.hideturtle()
coins.remove(found)
t.shapesize(1+points/5., outline=1+points)
points += 1
writer.write("{0} points".format(points),
align="center", font=('Arial', 24, 'bold'))
## End of script
You can see a screenshot of a run of this script here:
http://www.dropbox.com/gallery/2016850/1/TurtleCollector?h=6b370a
The script could be expanded in several ways, e. g. for
doing statistical investigations or examinig how the
result depends on different parameters like drunkenness etc.
Or you distribute the coins randomly ... Does that alter
the average "harvest"?
Just a suggestion ...

Hello,
I was just playing with the turtle module, and thought it was an
interesting way to augment the introduction to python (I teach college
students, who haven't had any programming). It's a great way to
introduce functions, for-loops, and general program structures.
After a bit of playing, I realized that I couldn't think of many
examples which use turtle with conditional structures (if- and while-
statements), or functions that return values, as opposed to
"procedures" like:
def square(length):
forward(length)
right(90)
forward(length)
right(90)
forward(length)
right(90)
forward(length)
right(90)
If-statements could possibly be used with some sort of random behavior
(if rand()<0.5 ...). Are there any other situations, using turtle,
that these structures would be natural?

It didn't form 2.5 to 2.6 (at least not intentionally). But with the

more in Python 3.x.
More info.
Yes, there is no tracer attribute...when the object is created.
But watch this (Python 3.1):
import turtle
tooter = turtle.Turtle()
tooter.tracer
Traceback (most recent call last):
File "", line 1, in
tooter.tracer
AttributeError: 'Turtle' object has no attribute 'tracer'
tooter.hideturtle()

Now, after setting hide, speed, update, a tracer exists.
No,
>>> import turtle
>>> turtle.tracer
>>> help(turtle.tracer)
Help on function tracer in module turtle:
tracer(n=None, delay=None)
Turns turtle animation on/off and set delay for update drawings.
Optional arguments:
n -- nonnegative integer
delay -- nonnegative integer
If n is given, only each n-th regular screen update is really
performed.
(Can be used to accelerate the drawing of complex graphics.)
Second arguments sets delay value.)
Example:
>>> tracer(8, 25)
>>> dist = 2
>>> for i in range(200):
fd(dist)
rt(90)
dist += 2
>>>
The reason for this is, that the turtle module (the new one as well as
the old one) has a vers special design: The methods of class Turtle are
also available as functions (which are in fact methods calls of an
anonymous turtle). The same holds for the methods of TurtleScreen.
The intention behind this design is that you can use the module in an
OOP way as well as with procedural programming (especially for beginners).
When using objects I normally use
from turtle import Turtle, Screen
screen = Screen()
# that creates singleton object, the screen the turtle acts on
and I create as many turtles as I need from the Turtle class
So turtle.tracer() doesn't make sense anymore
Is that supposed to happen? That explains why there was no error
when I set the turtle attribute instead of the screen attribute.
You do not 'set the turtle attribute', you call the tracer function of
the turtle module
And, of course, setting the turtle attribute accomplishes nothing,
as actual tracing is controlled by the screen attribute as you say.
Among them is the tracer method, which in fact does not control single
turtle objects but all the turtles on a given screen.
So there is an icompatibility beween 2.6 and 3.x
But as far as I have understood, this doesn't concern the problem
reported by mensator.
Only that the problem is hidden when tracing is off, as the nhops
variable is never evaluated when trace is off.
Nevertheless I'd like to see a working Python 2.5 version of your script.

I hadn't noticed because I usually have tracing turned off (tracing
off
takes 3-4 seconds, tracing on takes 6-7 minutes).
In 3.1, tracing is now a screen attribute, not a turtle atribute.
I have no idea why

I'd like to help with your problem but I'd much better be
able to analyze it, if I had a version of your script,
which works as you intended with Python 2.5 and the old
turtle module. Could you please post it?
(The one you posted below uses some commands of the
turtle 2.6 module which are not present in 2.5, so it
doesn't run with Python 2.5)
Regards,

Had to change to
tooter = turtle.Turtle()
tooter.screen.tracer(False) # tracer now a screen attribute
to turn tracing off in 3.1.
Naturally, having tracing on caused my program to crash. The 2.6
version
seemed to work, but only because turning off tracing as a turtle
attribute
works in 2.6.
So I turned it back on and it crashed too.
2.5 worked okay.
The reason is that code in turtle.py was chabged from
v2.5
if self._drawing:
if self._tracing:
dx = float(x1 - x0)
dy = float(y1 - y0)
distance = hypot(dx, dy)
nhops = int(distance)
to
v3.1
if self._speed and screen._tracing == 1:
diff = (end-start)
diffsq = (diff[0]*screen.xscale)**2 + (diff[1]
*screen.yscale)**2
nhops = 1+int((diffsq**0.5)/(3*(1.1**self._speed)
*self._speed))
Unfortunately, that calculation of nhops is illegal if diffsq is
an .mpf (gmpy
floating point). Otherwise, you get
Traceback (most recent call last):
File "K:\user_python26\turtle\turtle_xy_Py3.py", line 95, in

nhops = 1+int((diffsq**0.5)/(3*(1.1**self._speed)*self._speed))

So when using gmpy, you have to convert the .mpz to int before calling

Suppose you have your data given as a dictionary:

'd':(15,20),
'e':(18,23)}
Then the following not particularly elegant

algorithm will solve your problem:
def values(key):
return set(range(data[key][0], data[key][1]+1))
keys = list(data.keys())
result = []
while keys:
k = [keys[0]]
keys = keys[1:]
v = values(k[0])
for l in keys[:]:

v.update(values(l))
k.append(l)

A text editor would be a good feature for future versions. Regarding the naming of functions: I named them in the way that seemed best to me. You seem not to agree, you like the way your functions are named better, and there's little point in arguing over which convention is truly better. The convention I chose is the one that seemed ideal to me. I did consider naming the functions the same way you did for consistency, but I decided not to compromise the quality of PythonTurtle just to be compatible with a module that my users may not even use. That's the advantage of not developing for the standard library. In fact those elementary commands you use were present already in the old turtle module. When I decided to extend the old turtle module a primary requirement was that it remains 100% compatible to the old one. New versions of a module in the standard library must not break code of previous users of that module. In short: I did not name these functions but I had to use the names that already were there. Nevertheless I'd prefer left and right over turn even today, especially for kids as I argued before. Regards, Gregor It would be certainly a good thing if one had a similar environment using Tkinter, preferably also as part of the standard distribution of Python accompanying the turtle module.

I agree that it shouldn't be difficult; The question is whether someone will step up and do it.

Hi Ram, that's indeed a nice starting point for kids to doing turtle graphics, although currently it seems to implement only a very small subset of Python's turtle module's capabilities, even less than those of the old turtle module (that shipped with Python upto 2.5). Moreover I have to complain that you decided to use different commands for the turtle's actions - go instead of forward, turn instead of left and right etc. First I think left and right are more intuitive than turn as they do not need negative angles as arguments, which might matter for young children. Also I cannot see the advantage of cammands like visible() or invisible() over showturtle() and hideturtle() But second even kids - when learning how to program - will arrive at a point where it's no more problem to use an editor like IDLE so they could easily switch to Python's turtle module. That would be even easier if they had not to learn a new command set. Moreover a learning environment like PythonTurtle needs something like an editor - at least a simple one - in order to create programs that can be run repeatedly. Coding, that's creating programs - not only issuing a sequence of cammands interactively.

ANN: Python's turtle module: collection of examples + demoViewer
Hi all, A few days ago I've created a repository of turtle graphics demos/applications, that use Python's new turtle module. You can find it at at google code: http://python-turtle-demo.googlecode.com There are two versions of the collection: one for use with Python 3.1 and one for use with Python 2.5 / 2.6. The latter contains a *** backport of version 1.1 of the turtle module *** *** (from Python 3.1) to Python 2.5 / 2.6 *** Among others it contains all the examples I have demonstrated at Pycon 2009 and at EuroPython 2009. Moreover it contains the demoViewer (which is also in the source distribution of CPython) that lets you select the examples via a menu, display their source code and execute them in parallel. If you are interested to amend some of these examples, add some explanatory material or contribute additional examples, please tell me so I could add you as a committer to the project. I'd be glad to expand the repository whith interesting examples and applications using the turtle module. If you have questions concerning the examples, feel free to ask here or ask me directly via my email-address. I hope this collection will prove to be useful.

do not understand the source of the problem. I do not try to pickle
an instancemethod directly. The dict does apparently contains only

Please come to Vienna and learn the local slang. You would be surprised how beautiful and expressive a language mixed up of a lot of very different languages can be. Same for music. It's the secret of success of the music from Vienna. It's just a mix up of all the different cultures once living in a big multicultural kingdom.

That is highly domain and customer specific individual logic, that the costumer knows best. (For example variation logic of window and door manufacturers) He has to understand the code, so that he can verify it's correct. We are in fact developing it together. Some costumers even are coding this logic themselves. Some of them are not fluent in English especially not in the computer domain. Translating the logic into a documentation is a waste of time if the code is self documenting and easy to grasp. (As python usually is) But the code can only be self documenting if it is written in the domain specific language of the customer. Sometimes these are words that are not even used in general German. Even in German different customers are naming the same thing with different words. Talking and coding in the language of the customer is a huge benefit.

I would recommend to drop the support team and the management that even considers this. This PEP is not a technical question. Technically it would no change much.

jython: user-defined modules
Dear all, I hope my question is here in the right place... What I want to achieve is a communication between Java and Python. We have a pretty strong framework of existing python scripts and modules. Now I want to use jython in order to faciliate the communication between another Java framework. But I`m currently stuck with jython: Trying to import the user-defined python modules, these cannot be found. I read a lot about the jython registry and I setup a $HOME/.jython file where I created a python.path=... resource, however, when I start the jython command line and type print python.path then this property is not found. Passing it with the -D option does not work as well, or maybe I`m too confused to make it work anyway? Any help would be great!

Webprogr: Link with automatic submit
Hi,
As I am no expert web programmer I thought I'd better ask the experts if
there is a simpler or better solution to my problem than the one I am
thinking of. (using TurboGears)
The problem
---
I have a form. Ok. you can submit, validate it etc.
Now I have a link on that form to another page.
What I want is that the form gets automatically submitted and validated
before the browser follows the link. If the validation has errors the
link should not be followed.
My solution
---
1. client side solution
First I thought I just make a little javascript function like this:
function xy(url) {
document.form.submit();
parent.location=url;
}
The problem is that submit works ansynchronisly. I do not get a return
code to decide if to follow the url or not. Furthermore the form does
not get submitted if there is the line parent.location=url; .
2. server side solution
I thought of including a hidden field and include directives for my
controller method to raise the redirection if no validation errors are
there.
function xy(url) {
document.form.hiddenfield.value = "redirect_to: " + url;
document.form.submit();
}
@expose
def mycontroller(self, *args, **kwargs):
#do the usual saving stuff
if hasattr(kwargs, 'hiddenfield'):
#parse the JSON or mini-langage and do the redirection, when no
#validation errors
As there might be more other directives necessery for client-server
communciation I thought of setting the hiddenfield value to JSON or a
self made mini-language and parse this in the controller.
Is this a good solution?
Are there any other options?

Interpretation of UnhandledException.rpt
Hi, in a windows server python application I receive once a week suddenly and not reproducible the following error. UnhandledException.rpt file: //=== Exception code: C090 FLT_INVALID_OPERATION Program: C:\Python24\python.exe Date: 6/ 6/2006 14:36:13 (MM/DD/ HH:MM:SS) Fault address: 00E9ADF0 01:00019DF0 C:\in4\inforCOM\Prod\InforDbCOM_Server.dll Registers: EAX:012BDAA0 EBX:012ADF50 ECX:B0D6 EDX:012BDAA0 ESI:012ADF50 EDI:0096A8C0 CS:EIP:001B:00DC4DC7 SS:ESP:0023:0021EF4C EBP:02E91EF0 DS:0023 ES:0023 FS:003B GS: Flags:00010212 Call stack: Address Frame 00DC4DC7 02E91EF0 0001:3DC7 C:\Python24\DLLs\psycopg.pyd 2D36302D 36303032 *** Exception while writing report! *** Do I read this correct, that the problem is in the InforDbCOM_Server.dll?

I also had to set the paths for the imports and current directory
manually (why?). This worked for me:
#!y:/python24-win32/python24.dll
import sys
import os
sys.path =
["","y:\\","y:\\python24-win32\\lib\\site-packages","y:\\python24-win32\\DLLs","y:\\python24-win32\\lib","y:\\python24-win32\\lib\\plat-win","y:\\python24-win32\\lib\\lib-tk","y:\\python24-win32",
"y:\\python24-win32\\lib\\site-packages\\win32",
"y:\\python24-win32\\lib\\site-packages\\win32\\lib",
"y:\\python24-win32\\lib\\site-packages\\Pythonwin",
"Y:\\python24-win32\\python24.zip","y:\\python24-win32"]
os.chdir("y:\\")
import hobel300
5. I also had to copy all required dlls from the c:\winnt directory (for
example pywintypes24.dll) into the current directory.
Thanks for this solution, works great, did not know that you can run
python programs even without a python installation on the local machine!
Nice!

Install libraries only without the program itself
Hi, My application is a client/server in a LAN. I want to keep my programs .py files on a central File Server serving all clients. The clients should load those over the LAN every time they start the program since I expect that they are rapidly changing and I dont want to update each client seperatly. On the clients there should only be python and the necessary libraries and third party modules (sqlobject etc.) installed. How do I make a setup script that only installs the necessary things, without the program itself. Is there a tool for that? -- Servus, Gregor http://www.gregor-horvath.com -- http://mail.python.org/mailman/listinfo/python-list
