Correct.

Output of my last interactive interpreter I wrote with
that toolkit.

Python 2.7.6 (default, Nov 10 2013, 19:24:18) [MSC v.1500 32 bit (Intel)] on win32
>>> 
psi runs psizero.py...
...psizero has been executed
>>> '€'
€
>>> print('€')
€
>>> u'€'
?
>>> print(u'€')
?
>>> u'\u20ac'
€
>>> print(u'\u20ac')
€
>>> 

And if I cut/copy/paste something like this:
'ሴ䕧'
into that interpreter, it behaves like this ('??'):

>>> u'asdf'
asdf
>>> '??'
??
>>> 999
999
>>> "éléphant"
éléphant
>>> 'éléphant'
éléphant
>>>

Addendum.

I should say, I had also a lot of fun in writing my own
"styling engine".

Because when one has to deal with a language, which does
not recognize its own keywords...

>>> 1and 444
444
>>>

Sorry folks, I'd been up all night and messed that up completely.  I 
meant to say "Personally I am convinced that *IF* wxPython can't handle 
unicode *IT WILL BE* for the simple reason that it doesn't yet support 
Python 3 and we all know that Python 2 and unicode don't mix".  It would 
have been better still if I'd added right at the end "particularly 
well", with this being the impression I get from the bug tracker, with 
far fewer bugs being raised against Python 3 unicode that I'm aware of 
rather than Python 2.  I'm now crossing my fingers and legs and hoping 
that my impression is correct.

Quich answer.

That's PyShell, the wxPy interpreter.

You are right in pointing all this missmatch: byte string,
unicode, utf-8, mixing a "unicode" tool kit wiht a non
unicode native engine, plus plenty of related things, ...

You may be not aware. I contributed to wxPython from
practically 2.0, 2.1. 2.2 during 6, 7, 8 yeaurs, testing,
reporting about/with all versions, then I gave up.

---

Yout quote.
"Even if it is true that wxPython cannot handle Unicode text..."

It's a confusing vision and that's not correct. It's a little bit
more complicate than this.

There are some useful extensions to Tk written in Tcl. For example, 
there is tablelist - a tree widget or multicolumn listbox in pure Tcl. 
By passing it to the Tcl interpreter, you can wrap it up for Python - 
that's what Kevin Walzer did at

http://tkinter.unpythonic.net/wiki/TableListWrapper

It would take many man-month to reproduce this thing in Python.


Another example is the file open dialog (import tkFileDialog). On 
Windows and OSX, it uses the native variants, but on X11 it uses a very 
outdated, ugly and hard to use thing bundled with Tk. With just a few 
lines executed by some Tk.eval('source myfixes.tcl'), I overwrite this 
dialog box with the one created by Schelte Bron:
http://wiki.tcl.tk/15897

For reference, here is myfixes.tcl:

lappend auto_path [file dirname [info script]]
if {[tk windowingsystem] == "x11" } {
	package require fsdialog
	interp alias {} tk_getOpenFile {} ttk::getOpenFile
	interp alias {} tk_getSaveFile {} ttk::getSaveFile
	interp alias {} tk_chooseDirectory {} ttk::chooseDirectory
}

I think PyQt is slowly being pushed aside in favor of PySide, which is
more license-friendly for use in closed or open projects.  I would
recommend using PySide unless PyQt is a requirement for your project.

Except the issue that Pyside always seems to lag a bit behind Qt
releases, while PyQt usually supports more recent releases of Qt.

Besides that, according to what I've been reading on the PyQt mailing
list, support is impressive. The developer often fixes issues over
night, if there actually are any. And besides, again, a commercially
licensed PyQt itself isn't *that* expensive.

Sincerely,

Which is a bit odd, seeing as Pyside is an official Qt project.  It was
started by Nokia when they owned Qt, and now is hosted at the official
Qt web site.

For some people, it might be a lot.  Why waste money on something,
that has an almost-identical free-for-everyone version? (which also is

So, you have four options:

a) use PySide and Qt@Project, pay $0 and be sane (albeit saner than
   person B);
b) use PyQt4 and Qt@Digia, pay £350/£420 + £??? and be sane;
c) use PySide and Qt@Digia, pay £??? and look like a hypocrite (albeit
   less than person D);
d) use PyQt4 and Qt@Project, pay £350/£420 and look like a hypocrite.

DISCLAIMER: Some things are based on assumptions, many of which may be
            incorrect.

PS. For those living in the past without proper Unicode support: £ = GBP.

I didn't write the second paragraph. Please learn to quote, thanks.

For a commercial developer that doesn't appear much to me. I know Qt
applications that cost ~100.000 EUR per seat. Others are so valuable
that they simply aren't sold at all.

Wingware since recently uses PyQt and their prices don't seem to have
skyrocketed since the migration from PyGTK.

Because PySide is *far* from identical.

Thanks again for learning to quote correctly. I did not write this
paragraph.
 
> So, you have four options:

If you need something that's actually supported, Pyside (currently)
doesn't look like a credible option to me.

And for "home users", education etc., the GPL version of PyQt seems
perfect to me.

It is a bit strange but, back in the day, there wasn't a better multi-platform 
GUI option and, even today, Tk (and Tcl) remain attractive because it is 
supported on the many important platforms and does not have the license issues 
that some other GUI toolkits have had.  And because of inertia.  Also, Python 
is not alone in this: Perl and Ruby also have Tk bindings that work the same 
way, AFAIK.

Tcl is the language. Its standard interpreter is written in C, as with 
Python. (I do not know if there are other Tcl implementations.) Tk is 
the gui framework written, I believe, in a mixture of Tcl and C.

Tkinter (Tk interface) is entirely a Python to Tcl/Tk and back interface.

> With Tkinter in Python is it still using Tcl/Tk under the hood?

Yes.  _tkinter.c defines Python-callable functions that call Tcl/Tk C 
api functions. tkinter.py defines Python classes and methods. The 
methods call _tkinter functions. Most of the classes correspond to Tk 
widgets such as Button and Text.

> IE embeds the Tcl language interpreter into Python's interpreter?

Both interpreters run in one process.

 > If so I've always found

Tcl/Tk is only shipped with the Windows Python installer. On other 
systems, it is a separate install if not already present.

There once (over 10 years ago) was a project to re-write Tk entirely in 
C. What I read it that people decided that Tk made too much use of Tcl 
functions to make that worthwhile.

There have been starts on projects to write a gui framework based on 
Python and wrapped C libraries. PyGui is one, last updated July 2011.

That's not the impression I get from the PySide mailing lists. Work seems 
slow now everyone is a volunteer. For example, Qt 5 is not yet supported 
(there's no effort towards this according to the mailing list) and bugs seem 
to take a long time to be fixed. PyQt support is much better, even when I'm 
using it for a free project.

But to be honest, I don't believe that Python is the best choice for GUI

Hi Mark!

It is an advise, in which language somebody wants to code is of course 
everybodys free choice.

However, I believe according wxWidgets it would be better coding in the 
native language the system had been developed.
The other thing, specially if you would make a customer project, I don't 
know how to pack the app written in python in an installer. Perhaps I am 
wrong, and you could give me in exchange an advise ?!

I also believe in performance. An application written in C++, can be 
compiled easily on the target platform (like on windows systems) with 
it's native compiler.
How would it be with wxPython ?!


Thanks for your response

If you want your application to be actually user-friendly, you make it
available as an installer-less zip archive. It works with Python
applications, no matter whether they use PyGTK, wxPython or PyQt.

> Perhaps I am wrong, and you could give me in exchange an advise ?!

Python is probably the "best" language for application implementation in
general. Anything that would really need to be faster than python
itself allows can easily be implemented in "compiled" Python à la Pyrex
et al.

It isn't an issue.

With that pathological non-operating system Microsoft (Not Responding),
as soon as your application has to do any I/O, or if there's any other
process (virus scanner, file system indexer) running that does I/O,
any computer will be unusable for productive work anyway.

On an actual operating system, the attitude of the developers (do they
actually care or just don't give a darn) is *the* critical issue for
end-user productivity. If a developer makes a statement such as
of "just get a faster computer" or "just get more RAM", then (s)he
probably doesn't give darn. C++ applications, just like Java
applications, tend to leak horrible amounts of memory these days, just
because the vendors/developers don't care.

Sincerely,

Wolfgang
