I use a text editor (EditPlus under Windows) as a mini IDE. Some text editors have a concept of "tools" where you can run the "tool" from within the editor and it calls an external program to run the source code in the editor. With EditPlus the tool looks something like: Menu text: Python Command: C:\Python25\python.exe Argument: "$(FileName)" Initial directory: $(FileDir) Capture output: [X] Output from the program run is captured in an "output window". A full blown IDE it ain't but handy it is.

Re: what IDE is the best to write python?
I have a "thing" about editors; a good editor is my tool of trade! I
have tried many editors over the years mainly in the MS Windows, Linux
and IBM mainframe environments. After all this I really like EditPlus
(and the a slightly lesser extent Textpad). What both have in common is
their "Clip Library" or "Clip Text" (I think its called in Textpad).
A Clip Library is a simple text file that appears in a side panel next
to the main edit panel. Double click on a Clip Library element and it is
automatically pasted into the edit panel at the current cursor position.
The Clip Library content can also be pased around highlighted text in
the edit panel.
Here is a simple of an EditPlus Clip Library for what I call a "short
script":
#T=Short script
^# ^!.py
^# The purpose of this script is
def main():
{code here}
main()
#T=Next Clip Library element
#T= defines the name of the Clip Library element
^# the "^" character must proceed a character that is normally a Clip
Library syntax character but which you want to use in another context (a
Python line comment in this case)
^! is the cursor positin after the Clip Library element has been
inserted, in this case the cursor is positioned to alloy the name of the
script to be typed
The Clip Library element ends when the Clip Library "parser" finds
either another element definition or the end of the file.
Clip Libraries are stored in simple text files.
This is such a simple concept but is so very productive. Who needs an
IDE?. I would love to have a Linux text editor (like Scite or GEdit)
that could do this.

Peter

Python 3 and easygui problem
I have just installed Python 3. I have been using Tkinter and easygui
(with Python 2.5.4) for any GUI needs. I have just started to port some
of my existing scripts to Python 3 and discovered problems with easygui.
I was using the following script for testing:
from easygui import *
import sys
while 1:
msgbox("Hello, world!")
msg ="What is your favorite flavor?"
title = "Ice Cream Survey"
choices = ["Vanilla", "Chocolate", "Strawberry", "Rocky Road"]
choice = choicebox(msg, title, choices)
# note that we convert choice to string, in case
# the user cancelled the choice, and we got None.
msgbox("You chose: " + str(choice), "Survey Result")
msg = "Do you want to continue?"
title = "Please Confirm"
if ccbox(msg, title): # show a Continue/Cancel dialog
pass # user chose Continue
else:
sys.exit(0) # user chose Cancel
I have changed the easygui source to Python 3 'import' and 'print'
requirements and the initial message box in the above script displays
fine fine. However the subsequent message boxes do not display and after
the script completes I get the following error message:
-- Python 3 --
Traceback (most recent call last):
File "easyguidemo.py", line 10, in
choice = choicebox(msg, title, choices)
File "C:\Python30\lib\site-packages\easygui.py", line 703, in choicebox
return __choicebox(msg,title,choices,buttons)
File "C:\Python30\lib\site-packages\easygui.py", line 824, in __choicebox
choices.sort( lambda x,y: cmp(x.lower(), y.lower())) # case-insensitive sort
TypeError: must use keyword argument for key function
Output completed (7 sec consumed)

Fixing this is a bit beyond my skills and I was wondering whether anyone
has any thoughts.
I am happy to post a copy of my revised easygui.py script.
Regards,
Peter

Re: Python 3 and easygui problem
Terry, I have not used PyPI before and feel a little uneasy about putting this modified script into such a public place. I have previously contacted Steve Ferg (the original developer of EasyGui) but have not had a reply. Clearly the bulk of the work is his still where as the modifications are mine (and several helpers from the Python List). Until I work out what I ought to do I have attached a copy of my script (and the test script I have been using) as is. I would really appreciate any comments. If Steve does not reply and further testing proves my modified script is sound then I will certainly look at a 'public' release.

Re: Python 3 and easygui problem
John Machin said:* *"... the knowledge that you had attempted to contact Steve Ferg and have not yet had a response was not available on c.l.py and in any case is not a justification for incitement to hijack." John, I resent the implication that I am trying to hijack Steve's project. This was never my intention. I am uneasy about posting this rebuttal on the list as this is not what I think lists like this are for; but given your response I will post this one reply in my defence. I think that if you want to follow up this matter do it off line. For your information I have since been in contact with Steve and sent him a copy of my code. Its been my experience that there are some users of these lists who ought to hesitate before they jump in because they often are not in full possession of all the facts. Once again (and for the last time) this was a personal project, I offered to share my additions to Steve's work in an informal way to anyone who helped me with fixing error responses I was getting - its a very long bow to draw to say this constitutes hijacking. It was NEVER my intention to hijack anyone's work and I resent the accusation. To end, I have included below a statement that I added to the script that I sent to Terry: - This is an experimental version of EasyGui that has converted the latest 'official' version so that it will run under Python 3.0.1 The script is still being tested and any comments would be appreciated.

Re: Emacs vs. Eclipse vs. Vim
What I have done is skipped the whole Vim/Emacs obscure editor thing and opted for PyScripter (see http://mmm-experts.com/Products.aspx?ProductID=4 ). It might not be as complete/complex as these other editors but it is easy to use and just lets me get on with the task of cutting code. As a fall-back I also use EditPlus (see http://www.editplus.com/index.html ). Its only for Windows and its shareware so you need to pay for it. Its clip library makes it a VERY GOOD text editor. It's a real shame there are NO text editors with such a comprehensive and easy to modify clip library function (I would be really pleased to be proven wrong on this last point :-) ). However, the best advice I think that can be given about editors is keep trying them until you find the one YOU like. We all like different things, especially when it comes to editors.

Only the text on the line after the "T#" appears in the clip lib side panel. Double click on the text label and EditPlus inserts the clip text into the document being edited. The "^!" is where the cursor sits after the clip insertion. Clips can be inserted "around" existing text. Very neat; if you use Windows its really worth a try.

Re: What IDE support python 3.0.1 ?
Sam (I presume),
Like you I am also in the process of learning to program in Python. I
have been using Python 2.5.2 for quite some time but recently made the
switch to 3.0.1. Why? Because I read an article where Guido van Rossum
himself recommended that anyone starting out learning Python now was
wasting their time if they didn't start with Python 3. Some folks on
this list will tell you there is not much difference and that seems to
be true but I pleased that I made the switch.
Now for your question about an IDE. I am presuming you are just
beginning, perhaps done some programming in another language and
probably using a Windows based PC. Given that there are some things I
would recommend you stay away from (this will get the juices going :-)
): Vi, Vim, Emacs and all those old fashioned UNIX/Linux based editors -
they are just too hard and why bother anyway, there are much more
civilised ways of proving your manhood. Eclipse is also an over-kill. I
would recommend any of the popular text editors; most will recognise
Python files.
I can tell you what I use:
*EditPad+* - http://www.editplus.com/index.html - A great general
purpose text editor that has the additional benefit of clip libraries
(what?). This might not seem important but it is a great time saver. A
clip library is a text file of code snippets that when you
'double-click' the required clip the editor inserts that code at the
current cursor position. For example the following is a clip I use for
the heading of a short script file:
#T=Short script
^# ^!.py
^# The purpose of this script is
def main():
{code here}
main()
After the clip has been inserted the cursor is positioned where the "^!"
string is (before ".py") waiting for the script name to be inserted. You
just build these clips to suit yourself. TextPad is another text editor
with the same features.
The main drawback with EditPlus is that when you run a Python script
from within EditPlus and that script uses stdin (eg. an input()
function) the editor can't handle it and you get an error message. I
overcome this problem by using easygui (http://easygui.sourceforge.net/)
dialogs for text input; a piece of cake :-) . Another drawback is that
EditPlus is shareware and you have to pay for it (US35).
*SciTE* - http://www.scintilla.org/SciTE.html - Scite is a very good
little editor, it does not have the "bells and whistles" that editors
like EditPlus have but it does recognise Python files and can run them
from within the editor. It can also handle stdin (not that elegantly,
but it works) so you don't need the easygui work-around and its free.
*IDLE* - the built-in Python IDE. I have it configured so that the
editor panel loads first rather than the Python prompt. Everything runs
in IDLE!
*PyScripter* - http://code.google.com/p/pyscripter/ - From the web site:
"PyScripter is a free and open-source Python Integrated Development
Environment (IDE) created with the ambition to become competitive in
functionality with commercial Windows-based IDEs available for other
languages." This is a true IDE with most of the things you would expect.
However, I find that it gets a bit buggy at times. It does support
Python 3 and is free so its worth a try.
There are several other good Python editor/IDE's but they require
wxPython and it has not yet been made available in a Python 3 compatible
version.
I hope that helps. Give me a reply if you want any more help with any of
these things. Easygui is something that is really worth getting to know.
A copy of Python (Second Edition) by Toby Donaldson (ISBN 13:
978-0-321-58544-8) is another good thing to have when you are learning.
Regards,
Peter

Python internals
Hi! I am slowly teaching myself Python. I was reading David Beazley's excellent book "Python - Essential Reference"; in particular about variables. Let me quote: "Python is a dynamically typed language in which names can represent values of different types during the execution of a program. In fact the names used in the program are really just labels for various quantities and objects. The assignment operator simply creates an association between a name and a value. This is different from C, for example, in which a name (variable) represents a fixed size and location in memory..." As an old mainframe programmer, I understand the way C does things with variable but this text got me wondering how Python handles this "association" between variable name and value at the lower level. Is it like a fifo list? If there is any Python guru that can help I would be most interested in your thoughts.

Just a quick correction - "as the original poster is" is a bit of a jump that does not reflect my original question. I DO understand how C and other programming languages handle variables internally (the bits of actual memory reserved, etc. etc.) and that's why I asked the question in the first place. If Python doesn't do it like C and the others then what mechanism does it use - it's the sort of issue that helps me understand how the language is interacting with the underlying operating system/hardware. By way of background, in my ancient working days I looked after mainframe systems written in COBOL and Natural (and some assembler which I never had to support personally but my staff did).

Bill, I have a similar length of experience with python to you.

wxPython problem
I am trying to teach myself how to program in Python and use wxPython
for GUIs. I am using PyScripter, IDLE and EditPlus as my IDEs. I have
experienced an odd problem where I run a script once and it runs fine.
Run it again and I get an error and the script fails.
If the script is run directly from Python ('Run' from Windows Explorer)
or from EditPlus (in which I have a "user-defined tool" which calls
C:\Python25\pythonw.exe with the parameter of $(FileName)) then there is
*never* any error, no matter how many times the script is run.
Close down PyScripter or IDLE and then start either up again, load the
script and run it - it runs fine. Run it again and it fails. It seems
like something is already set in memory and cant be re-set (my lack of
knowledge is showing here :-( ).

appreciated.

correct version of Rpyc (which is required to run the remote Python
engine but it now seems to be working fine. And the "Reinitialise the
Python engine {Alt]+[F2]" does need to be done between script runs.
Given all that, the script now runs multiple times in PyScripter. The
script still only runs ONCE in IDLE but I can live with that.
In case others find this message from a search; I am using Python 2.5.2
and it requires rpyc-2.60.zip from the Rpyc download page (see
http://rpyc.wikispaces.com/ click on the "Download" link and make sure
you select the "main" link under the "Packages" column at Sourceforge.
You will be shown a list of Rpyc versions. For Python 2.5.2 choose
Relese "2.60". This will save you the several hours its cost me.
Thanks again Stef.
Regards,
Peter

Re: Learning Python
James, I have several Python books and am currently working my way through John Zelle's PYTHON PROGRAMMING: An Introduction to Computer Science (Publisher: Franklin, Beedle & Associates, ISBN-10: 1887902996, ISBN-13: 978-1887902991). I think this is a very good introduction to both Python AND programming I would highly recommend it. If you finish the Zelle book then you can go onto Problem Solving With Algorithms And Data Structures Using Python by Bradley N. Miller and David L. Ranum (Publisher: Franklin Beedle & Associates, ISBN-10: 1590280539, ISBN-13: 978-1590280539). These are equivalent to Python 101 and 201.
