ANN: matplotlib-0.80

[John Hunter]

matplotlib is a 2D graphics package that produces plots from python
scripts, the python shell, or embeds them in your favorite python GUI
-- wx, gtk, tk, fltk and qt.  Unlike many python plotting alternatives
is written in python, so it is easy to extend.  matplotlib is used in
the finance industry, web application servers, and many scientific and
enginneering disciplines.  With a large community of users and
developers, matplotlib is approaching the goal of having a full
featured, high quality, 2D plotting library for python.

A lot of development has gone into matplotlib since the last major
release, which I'll summarize here.  For details, see the notes for
the incremental releases at http://matplotlib.sf.net/whats_new.html. 

Improvements since 0.70

 -- contouring: 

Lots of new contour funcitonality with line and polygon contours
provided by contour and contourf.  Automatic inline contour
labeling with clabel. See
http://matplotlib.sourceforge.net/screenshots.html#pcolor_demo

 -- QT backend
Sigve Tjoraand, Ted Drain and colleagues at the JPL collaborated
on a QTAgg backend

 -- Unicode strings are rendered in the agg and postscript backends.
Currently, all the symbols in the unicode string have to be in the
active font file.  In later releases we'll try and support symbols
from multiple ttf files in one string.  See
examples/unicode_demo.py

 -- map and projections

A new release of the basemap toolkit -  See
http://matplotlib.sourceforge.net/screenshots.html#plotmap

 -- Auto-legends

The automatic placement of legends is now supported with
loc='best'; see examples/legend_auto.py.  We did this at the
matplotlib sprint at pycon -- Thanks John Gill and Phil! Note that
your legend will move if you interact with your data and you force
data under the legend line.  If this is not what you want, use a
designated location code.

 -- Quiver (direction fields)

Ludovic Aubry contributed a patch for the matlab compatible quiver
method.  This makes a direction field with arrows.  See
examples/quiver_demo.py

 -- Performance optimizations

Substantial optimizations in line marker drawing in agg

 -- Robust log plots

Lots of work making log plots just work.  You can toggle log y
Axes with the 'l' command -- nonpositive data are simply ignored
and no longer raise exceptions.  log plots should be a lot faster
and more robust


 -- Many more plotting functions, bugfixes, and features, detailed in
the 0.71, 0.72, 0.73 and 0.74 point release notes at
http://matplotlib.sourceforge.net/whats_new.html

[ANN] pylint 0.6.4

[Sylvain Thénault]

Hello all,

I'm pleased to announce a new release of PyLint. This release mainly
fixes multivalued options bug and a systematic crash with python 2.2.
Users should also use the latest logilab's common library (0.9.3).


What's new ?

* allow to parse files without extension when a path is given on the
  command line (test noext)

* don't fail if we are unable to read an inline option  (e.g. inside a
  module), just produce an information message (test func_i0010)

* new message E0103 for break or continue outside loop (close #8883,
  test func_continue_not_in_loop)

* fix bug in the variables checker, causing non detection of some
  actual name error (close #8884, test
  func_nameerror_on_string_substitution)

* fix bug in the classes checker which was making pylint crash if
  object is assigned in a class inheriting from it (test 
  func_noerror_object_as_class_attribute)

* fix problem with the similar checker when related options are
  defined in a configuration file

* new --generate-man option to generate pylint's man page (require the
  latest logilab.common (= 0.9.3)

* packaged (generated...) man page


What is pylint ?


Pylint is a python tool that checks if a module satisfy a coding
standard. Pylint can be seen as another pychecker since nearly all
tests you can do with pychecker can also be done with Pylint. But
Pylint offers some more features, like checking line-code's length,
checking if variable names are well-formed according to your coding
standard, or checking if declared interfaces are truly implemented,
and much more (see http://www.logilab.org/pylint/ for the complete
check list). The big advantage with Pylint is that it is highly
configurable, customizable, and you can easily write a small plugin to
add a personal feature.

The usage it quite simple :

$ pylint mypackage.mymodule


This command will output all the errors and warnings related to the
tested code (here : mypackage.mymodule), will dump a little summary at
the end, and will give a mark to the tested code.

Pylint is free software distributed under the GNU Public Licence.

ANN: numarray-1.3.0

[Todd Miller]

Release Notes for numarray-1.3.0

Numarray is an array processing package designed to efficiently
manipulate large multi-dimensional arrays.  Numarray is modelled after
Numeric and features c-code generated from python template scripts, the
capacity to operate directly on arrays in files, arrays of heterogeneous
records, string arrays, and in-place operation on memory mapped files.

I. ENHANCEMENTS

1. Migration of NumArray.__del__ to C (tp_dealloc).  Overall
performance.

2. Removal of dictionary update from array view creation improves
performance of view/slice/subarray creation.  This should e.g. improve
the performance of wxPython sequence protocol access to Nx2 arrays.
Subclasses now need to do a.flags |= numarray.generic._UPDATEDICT to
ensure that dictionary based attributes are inherited by views. 
NumArrays no longer do this by default.

2. Modifications to support scipy.special.

3. Removal of an unnecessary getattr() from ufunc calling sequence.
Ufunc performance.

II. BUGS FIXED / CLOSED

1179355 average() broken in numarray 1.2.3
1167184 Floating point exception in numarray's dot()
1151892 Bug in matrixmultiply with zero size arrays
1160184 RecArray reversal
1156172 Incorect error message for shape incompatability
1155538 Incorrect error message when multiplying arrays

See
http://sourceforge.net/tracker/?atid=450446group_id=1369func=browse
for more details.

III. CAUTIONS

This release should be backward binary compatible with numarray 1.1.1
and 1.2.3.

 I'm not quite sure of your question but with the second style you're not
 attempting to change the original list but make a copy. That's perfectly
 easy to do in Python as it is. The exampmle is a cautionary one about
 changing the list on which you are iterating.

For reasons that are beyond me widgets do not increase the reference count

elsewhere, e. g. into the App instance, to prevent it from being
garbage-collected when the image1 variable goes out of scope.

If that works for you and your users, fine - the main point of this

Because I stumbled across the same 'feature' just recently, I think it's
good to give a reference...

From http://tkinter.unpythonic.net/wiki/Images

Something that seems to bite every new Tkinter programmer at least
once: you've loaded a PhotoImage, applied it to a Button, Label, or
other widget, and nothing shows up - because you referenced the image
only via a local variable, so it went out of scope and got deleted
before the widget ever appeared. The usual solution is to store a
reference to the image as an attribute of the widget that is to display it.

You might just call this a bug in Tkinter, but the reality isn't quite
that simple... Tk images are not first-class objects: when you apply one
to a widget, you do not in any sense pass a reference to the image.
Instead, you just pass a name, which Tk looks up in an internal table of
defined images (from which images can only be deleted manually). From
Tkinter, passing a PhotoImage as a parameter actually only sends the
str() of the image object to the Tcl side: this is just a string, the
randomly-generated name assigned when the object was created. No
reference to the image itself means no reference counting means no
way for the Python side to be notified when the image is truly no longer
used. If Tkinter didn't delete images when no Python reference to them
existed, they would be unavoidable memory leaks.

Inelegant

[Dan]

I've just begun playing with Python, and so far I like what I see.
It's a very elegant language.  But I've found something that's, well,
a bit ugly.  Maybe someone can point out to me where I'm wrong.

If you use triple quotes to define a string, then the newlines are
implicitly included.  This is a very nice feature.  But if you're
inside a function or statement, then you'll want the string to be
positioned along that indentation.  And the consequences of this is
that the string will include those indentations.

For example:

def SomeFunction()
   if SomeCondition:
  MyString = 
  
  The quick brown fox
  
  print MyString

The output will be:

  The quick brown fox

But what you really want is:

The quick brown fox

The way around it is to write the function thus:

def SomeFunction()
   if SomeCondition:
  MyString = 

The quick brown fox

  print MyString

But that's just ugly.  It seems to me that the string should be
interpreted with the edge along the indentation line, not from the
start of the line.  But that would probably create other problems.

Yeah, it's definitely a wart.  So much so that recent Python

 from textwrap import dedent

Why attach a license that is not operative. That doesn't make sense
to me and will IMO just create confusion.

Because it's not your code. The tiny obligation that you have to satisfy 
is to say that some of the code comes from someone else and is available 
under such-and-such a license. That's it. You can keep the code hidden, 
you can charge whatever you like for it, but you have to attribute it 
properly. Open source licenses don't get much less restrictive than this.
 
 
 Well maybe this is a semantic problem. I wouldn't use the word attach
 here.

 Fair enough. The license text is included *for reference*, not because 
 it is *the* license for the derived work. In fact, it *can't* be the 
 license of the derived work because you are not the PSF.

 So what I seem obligated to do, is 1) Mentioning this came
 from the python distribution and 2) explain where this distribution can
 be attained and under what license.

 The minimum is:

 1) Put the copyright notice in.
 2) Reference a copy of the PSF License. (Practically speaking, a URL 
 will probably do.)
 3) List the modifications you made.
 4) Put your copyright notice in and whatever terms you want to apply.

Of course, IANAL and TINLA, so if you want real legal advice instead of 
advice from random newsgroup bums like myself, you should talk to a lawyer.
 
 
 Well if it comes so far I have to consult a lawyer I'd rather not publish
 it in the first place.

 Then take the (free) advice that you asked for.

 The only reason I'm concerned is that this is to be part of a tutorial

 You can't *quite* go that far if you are deriving code from Python, but 
 it's about as close as you can get. You still have those light 
 restrictions about attribution and notification of changes.

I'm not sure I follow. As far as I understand, I can license the result
however I see fit, as long as I go by the conditions for using the

 I see this as my contribution to the communities who has provided me

 otherwise to find out how to contribute legally, that is a hurdle
 I'm reluctant to take.

 You could take a look at what other people are doing. Most of us here 
 are writing and releasing software derived from Python, legally so and 
 without complication.

I would do that if I were just writing code I thought others could

with the same kind of license I found in the product I took some

Do you know the (apparently dead) project named e:doc? You can find it here:
http://members.nextra.at/hfbuch/edoc/
It's a kind of word processor that can produce final documents to various 
formats using backends, and one of the backends is for LaTeX.
It's written in Perl, but with Perl::Tk as a tool-kit, so it is quite close to 
Tkinter. There may be some ideas to steal from it.

Re: Compute pi to base 12 using Python?

 Now you've got me curious.  Why would an artist want the first 3003
 digits of pi to the base 12?

[Dick]
 He says,
 Do you know how I can get base12 pi?
 Because the chromatic scale is base12.

The problem is the encoding of the Text

For exampel i get 'f³r' but i want 'für'  (maybe reader with only an english

Supercomputer and encryption and compression @ rate of 96%

Take a document then or a 3D matrix document change it two random or

like a piece of paper then having the 1 and 0 add each other or the
0,1's canceling each other out 1+0=0 and 0+1=1 1+1=1 0+0=0 if you gave
the folds addresses like on a spread sheet there would be no math.
First A 1-24  would fold to k 1-24 down.(See Example A )  Then at F1-24
down two k 1-24 ( See example B )  If you written a very long letter
and then change it two binary code it would look like this.
   123456789.24

   123456789.24

   123456789...
 j.010101010101 Then from j-12 to j-1

   123456
 j.010101   Then from j-6 to j1

   123
 j.010  Then from j-3 to j1

   12
 j.01Then from j-2 to j1


 j.0 Then you would have
 1 bit to transfer over the
 Internet
The bit sent would be 0 and the key code would be F1-24,k 1-24,
I 1-24,K 1-24,j24,j1,j12,j1,j6,j1,j3,j1,j2,j1 and would unzip or be new
encryption you could encrypt or compress 100 terabits down to 1 bit of
information. Now if you take this idea from my web site you could make
this allot more complex and unbreakable. Data encryption 360 degrees
rotation document 90 degrees and encrypt on every angel then 45 degrees
change it two binary code do it again and again and fold it over like a
piece of paper then having the one's and zero cancel each other out. In
theory you could send a 100 terabit program to someone's computer and
have it unzip and run and install or make
A computer processor like the new 64 bit AMD have the bit unzip into a
large ram drive and buffer use one half of the 64 bit processor decode
the message and the main 64 bit run the numbers. Another way of doing
this is to have a parallel computers with using one of the processes
run the compressed 1 bit of information give the uncompressed a address
on the ram drive to change and not even go threw the processor and then
with different information on each machine compare and run statistics
on information on a 45 tflops supercomputer and turn that 45 tflops
computer into a 1 bit = 100,000 terabits to infinite as long as you
have the ram for storage! with my calculations 45 tflops wouldn't
matter any more it would be how much data you have on a 32bit operating
system changing that to a 1 bit system it would be 32 * 45tflops would
= 1440 tflops   Matter moves so fast that it intergreats and
deintergreats faster then any speed we can see it like water from a
hose at real close speed it moves in  lines.

Yeah, it's definitely a wart.  So much so that recent Python

This string will have the leading

I never liked any of the solutions that demand bracketing the string with 
expression brackets,
but I just had an idea ;-)

  class Dedent(object):
 ... def __init__(self, **kw): self.kw = kw
 ... def __add__(self, s):
 ... lines = s.splitlines()[1:]
 ... margin = self.kw.get('margin', 0)*' '

 ... return '\n'.join([line[mnow:] and margin+line[mnow:] or '' for

Normally you wouldn't pass **kw in like this,
you'd just write
 mystring = Dedent()+\

or

 mystring = Dedent(margin=3)+\

but  I wanted to control the print. Note the the first line, unless you escape 
it (ugly there)
is zero length and therefore has zero margin, which subverts the other 
shifting, so I just drop that line.
You have to live with the backslash after the + as payment for preferring not 
to have parentheses ;-)

  def foo(**kw):
 ... mystring = Dedent(**kw)+\
 ... 
 ... This makes

Thanks for looking John. For that I should take a little time to explain.
I tried to rename the variables, some of them were four words long. I 
got a couple of the renames wrong. Sorry.

Regarding 'works'. I meant that with a text file of four lines the code 
completed. With my desired size 11000 lines it didn't complete within 
the limits of my patience. I didn't try any other size.

Also I perhaps wrongly use the newsgroup threads paradigm in trying to 
restart my query with extra information (that turned out a little faulty).

Luckily the other branches yielded fruit.

PIL pilfont.py

Hi.

I tried to convert a bdf file using pilfont.py script. Instead producing
pretty font images, it complained like following.

**

gulim24.bdf...
Traceback (most recent call last):

Gulim is a korean font with KSX encoding.
The script worked fine with a ntimb08.bdf. So I suspect the script
doesn't like non-latin

Can anybody help me?

BTW, my previous problem with truetype() was solved. Some ttf files work and

A better idea when roughing out functions and classes is to insert a 
docstring describing what the function is going to do. That way you don't 
have to use 'pass' at all, and you don't have to remember to remove 
anything when you later add code. Alternatively use 'raise 
NotImplementedError' to tell you at runtime if you hit any such functions.

'convenient place to put a break when testing' implies you test by stepping 
through with a debugger. You should consider writing unit tests as a way of 
reducing the amount of debugging you need to do.

[ANN] pylint 0.6.4

[Sylvain Thénault]

Hello all,

I'm pleased to announce a new release of PyLint. This release mainly
fixes multivalued options bug and a systematic crash with python 2.2.
Users should also use the latest logilab's common library (0.9.3).


What's new ?

* allow to parse files without extension when a path is given on the
  command line (test noext)

* don't fail if we are unable to read an inline option  (e.g. inside a
  module), just produce an information message (test func_i0010)

* new message E0103 for break or continue outside loop (close #8883,
  test func_continue_not_in_loop)

* fix bug in the variables checker, causing non detection of some
  actual name error (close #8884, test
  func_nameerror_on_string_substitution)

* fix bug in the classes checker which was making pylint crash if
  object is assigned in a class inheriting from it (test 
  func_noerror_object_as_class_attribute)

* fix problem with the similar checker when related options are
  defined in a configuration file

* new --generate-man option to generate pylint's man page (require the
  latest logilab.common (= 0.9.3)

* packaged (generated...) man page


What is pylint ?


Pylint is a python tool that checks if a module satisfy a coding
standard. Pylint can be seen as another pychecker since nearly all
tests you can do with pychecker can also be done with Pylint. But
Pylint offers some more features, like checking line-code's length,
checking if variable names are well-formed according to your coding
standard, or checking if declared interfaces are truly implemented,
and much more (see http://www.logilab.org/pylint/ for the complete
check list). The big advantage with Pylint is that it is highly
configurable, customizable, and you can easily write a small plugin to
add a personal feature.

The usage it quite simple :

$ pylint mypackage.mymodule


This command will output all the errors and warnings related to the
tested code (here : mypackage.mymodule), will dump a little summary at
the end, and will give a mark to the tested code.

Pylint is free software distributed under the GNU Public Licence.

Re: Compute pi to base 12 using Python?

[François Pinard]

[Doug Schwarz]

 The chromatic scale is based on one twelfth powers of two, i.e., if
 the frequency of a note in the scale is f(n), then the frequency of
 the next note is given by f(n+1) = f(n) * 2^(1/12)

This easy view of things has been known for a long time, but has only
been popular (relatively) recently.  Traditionally, scale designers were
definitely running after rational proportions between scale notes, not
fearing some problems they necessarily create, because such scales are
often nicer and interesting to the musical ear.

I should relate this discussion to Python somehow! :-) Easy, as I have a
few Python programs doing various scale computations -- I should try to
bundle these together somewhere in my personal Web site, some day...

Re: smtplib does not send to all recipients

[dccarson]

OK, I've discovered the lost messages, but I'm still slightly confused
as to why they ended up there.  The messages were being delivered to
the local machine, box1.domain.com, even though I was addressing them
to user@domain.com.

My past experience with smtp mail has been that if I addressed the
domain explicitly, the mail would not stop at the local machine.  This
is in fact why the 'mail' utility is working.  If I use 'mail' to mail
something to user with no domain, it goes to the local machine, as I
would expect, but addressed to user@domain.com, it goes to the
corporate server.

So why does smtplib deliver to box1.domain.com?  If the local smtp at
box1.domain.com is configured such that this is correct behavior, I
guess I'd expect the 'mail' utility to do the same thing when handling
address user@domain.com.

By the way, the long vs. short usernames was a red herring.  Those with
.forward files were getting their mail.

Re: Compute pi to base 12 using Python?

[François Pinard]

[Bengt Richter]

 It might also be interesting to keep a running sum of the base 12
 values and use sum % 88 to select piano keys, to let it walk intervals
 outside of a single octave ;-)

The generated would then run from the low octaves to high octaves
monotically, then start over again and again.

Maybe a more interesting approach might be to pick the note in the same
octave, the octave below or above, where the new note is closest to the
preceding one.

 a random walk picture was interesting.

Using the closest note would have similarity with a random walk, given
 digits are seemingly random.  On a random walk, one gets away from
the departure point on average, the distance being proportional to
sqrt(N) where N is the number of steps.  So, when using the closest
note, one would need a corrective device nevertheless so notes are kept
near the middle of the range of comfortable audible frequencies.

 Anyone have an easy python midi interface for windows to play on the
 sound card?  I could generate a .wav file to play tones, but midi
 would be much more compact ;-)

There are surely many.  I use my own (Python) interfaces on Linux, and
even there, by combining a few tools, it is rather easy to get .WAV
files out of MIDI.  In any case, googling around might help.

 I don't know.  It probably works ok under Cygwin at least.

bc definitely works on cygwin, and is available at
http://gnuwin32.sourceforge.net/packages/bc.htm for windows. Make sure
you download both the dependencies and the binary package for it to
work. I put the dll from the dependancy archive in c:/winnt/system32
and it worked.

It should be noted that running the win32 bc from cygwin messed up my
terminal, so I recommend running it from a cmd window (which worked
fine).

Re: Get the entire file in a variable - error

[Jeff Epler]

It's not clear to me what you mean by the first line (gzip does not
output a file composed of lines, its output is byte-oriented).

Printing tst.getvalue() is probably not a very useful thing to do, since
it won't do anything useful when the output is a terminal, and it will
add an extra newline if you are redirecting to a file.

At least when close()ing the GzipFile before looking at the StringIO
instance's value, I get some bytes that gunzip just fine, giving the
original string.

Here's my interactive session:
 import gzip
 import StringIO
 io = StringIO.StringIO()
 z = gzip.GzipFile(test.gz, w, 5, io)
 z.write(\

Re: Supercomputer and encryption and compression @ rate of 96%

And how do you get the data back ?

1+0=0 == 0+0=0
0+1=1 == 1+1=1

let's say you have the end key : 0
then you want to decompress it , but in what ? 0 0 or 1 0

EOF-file missing

[Tor Erik Sønvisen]

Hi

From a client I read a file into a string using read().
On the server-side (it's a HTTPServer) i access the same string through the 
input stream rfile.
However all useful read-methods (readlines, readline, read) expect an EOF 
before terminating.
And for some reason the stream doesn't have the seek method either, so it's 
impossible to set the file-pointer to the end of the stream.
how can I access the whole string then?
Is it possible to add an EOF to the string before sending it from the 
client? Or maybe there are other solutions?

regards

60 phones.  If you want to get hands-on, upgrade that handset now!
This is a late addition to an already star-studded programme including
Greg Stein of Google, and many other key Python speakers and
projects.
Python-UK is part of the ACCU conference, Randolph Hotel,
Oxford, 21-23 April  (i.e. Thursday to Saturday next week).
There's still time to sign up and attend the event, in its entirety

py2exe + XML-RPC problem

[codecraig]

Hi,
  I tried to take the Monkey Shell script
(http://www.sharp-ideas.net/archives/2005/03/monkey_shell_us.html) and
make it into an executable.  I am making an executable for the server
piece (monkey_shelld.py).  So my setup.py looks like this

# setup.py
from distutils.core import setup
import py2exe
import sys
import xmlrpclib
import os
import string
from SimpleXMLRPCServer import *
from ConfigParser import *
sys.argv.append(py2exe)
setup(console=[{script: 'monkey_shelld.py'}],
data_files=[monkey_shell.conf])

...which i think is right.  I imported the same imports as
monkey_shelld.py uses (is that necessary??)  And i execute it like...

python setup.py py2exe

Anyhow, i run the setup and get a monkey_shelld.exe.  I can run the exe
and the server runs just fine.  Then I connect to the server using the
client (monkey_shell.py), and when I execute a command,  the client
side prints out an error...

xmlrpclib.ProtocolError: ProtocolError for 1.1.1.1:/RPC2: 500
Internal error

now, when i run the server script (i.e. python monkey_shelld.py),
everything works fine (i.e. i can send commands from client and get
server response), but when I try to use the server executable
(monkey_shelld.exe) I get the error (shown above) when I try to execute
a command.

Any ideas?  I am guessing that I am missing something from my setup.py.

Info that may be helpful in answering:
OS: win xp
Python ver: 2.4.1
py2exe ver: 0.5.4

Thanks!

curses for different terminals

[harold fellermann]

Hi all,
I want to use curses in a server application that provides a GUI for 
telnet clients. Therefore, I need the functionality to open and handle 
several
screens. Concerning 
http://dickey.his.com/ncurses/ncurses-intro.html#init
this can be done using the function newterm(type,ofp,ifp). However, this
function seems not to be defined in the python library. Does anyone know
how this can be done in python?

cheers,

Yup, I don't like that interface *nearly* as much as I do the gmail
interface. In gmail, I see threads as their subject headers, lined up
neatly. Threads which I've read are dimmed, and ones I haven't are
bolded. I see people's real email addresses . Threads in which I have
a personal conversation with one of the authors pop up to the top when
a private email comes in. Spam (The greatest news ever!) is filtered
out, and up until recently, it was very successful.

In short, the groups-beta interface is very inadequate compared to the
gmail one.

Peace

New-style classes, iter and PySequence_Check

[Tuure Laurinolli]

Someone pasted the original version of the following code snippet on 
#python today. I started investigating why the new-style class didn't 
work as expected, and found that at least some instances of new-style 
classes apparently don't return true for PyInstance_Check, which causes 
a problem in PySequence_Check, since it will only do an attribute lookup 
 for instances.

Things probably shouldn't be this way. Should I go to python-dev with this?
Demonstration snippet:
args={'a':0}
class Args(object):
def __getattr__(self,attr):
print __getattr__:, attr
return getattr(args,attr)
class ClassicArgs:
def __getattr__(self, attr):
print __getattr__:, attr
return getattr(args, attr)
if __name__ == '__main__':
c = ClassicArgs()
i = c.__iter__()
print i
i = iter(c)
print i
a = Args()
i = a.__iter__()
print i
i = iter(a)
print i

I tried adding the -D_REENTRANT flag to OPTS as suggested in the README, but that didn't seem to help/harm.  I searched the python lists and found lots of folks commiserating on HP-UX building, but no solutions other than building with '--without-threads', which simply isn't an option for me.  Any hints?


*blush*

Actually, the box on which I was building was HP 11.11.  I finally googled up a reference and this helped:

Just to make sure we understand what you want to do:

1. Are you doing an single process application that produces output on
many terminals?  ie the program is kind of like a service?

2. Are you doing an application with one session per terminal?  ie a
user starts your app in every terminal, no multi-term output from a
single process.

3. Are you doing an application that runs on one terminal but with many
virtual sessions (or screens), kind of like the `screen(1)` program or
the behaviour of the linux or Novell console?

Concerning

this can be done using the function newterm(type,ofp,ifp). However, this

Select one of the above, or describe more the desired situation if I

gotcha. I want to write a TCP server that handles incoming requests in
threads (one thread per request using SocketServer.ThreadingTCPServer).
Now, I want the server to use curses for client-server communication
(client will be telnet). Thus, my programm runs in a single process
(although several threads) and provides several curses screens (one for
each client.)

The address is irrelevant with SMTP.  What matters is
what server you connect to, and how it is configured
to handle the envelope you give it.
Mail forwarders ought to query a DNS for the MX

exchangers for that domain, regardless of what
server you actually connected to for the initial

Not sure this is relevant in your case, but it seems

should not) be looking up MX records for you, as far
as I know, while the mail utility might.

It's a kind of word processor that can produce final documents to

It's written in Perl, but with Perl::Tk as a tool-kit, so it is quite 
close to Tkinter. There may be some ideas to steal from it.

Thanks for this.  I've not seen it before
There are quite a few GUI semi-wysiwyg front ends to (La)TeX.
Interesting that there are so many, and that besides LyX few
seem to have succeeded.  Guess it's an important problem that
is also difficult.
My approach is a rather different - it is to exploit running
TeX as a daemon

This allows for Instant Preview.  My application is simply
a means of show-casing this capability.  And making it
useful in simple contexts.
So what I'm really wanting to do is provide a component for
projects such as e:doc.
Any, this might be a bit off-topic.
