There are many ways to build a GUI with Python. Some of the more
popular toolkits are Tk (tkinter), wxWidgets (wxpython), and GTK.
Explore those and see which one you like; I personally quite like GTK,
and the others have their fans too. There are GUI builders for each of
the above (I think; definitely wx and GTK do), or you can build
everything directly in code (my preferred style). Play around with it
and see what you like!

As a side point, though: You're using Google Groups to post, which
means your posts look messy, because GG doesn't follow internet
standards. Short of getting into Google and fixing Groups, the best
solution is to avoid using it; you can either use some other
newsreader (several here swear by Mozilla Thunderbird), or subscribe
to the email list, which carries all the same content:

https://mail.python.org/mailman/listinfo/python-list

Either way will spare you and us the hassles of malformed posts.

For learning, tkinter is probably the easiest because it comes 
with Python and you don't need to install anything else.  The
best way to get started with it is to search for tutorials and
examples on web.  Searching for "python tkinter" on Amazon shows
a few books but I don't know anything about them.

wxPython currently runs only with Python2, not Python3.  There
is a drag-and-drop form designer available for it but it is a 
commercial product that costs money.  It also comes with a 
useable (once you get used to it) form builder tool that works
by graphically manipulating a text tree of widgets.

The other big, widely-used GUI toolkit is PyQt.  It runs on 
both Python2 and Python3.  There is another version of it
called PySide which is API compatible with PyQt but has 
different licensing terms.  PyQt comes with a very good 
drag-and-drop form designer.

I have played a little with both wxPython an PyQt and found 
learning to use them from the web difficult because of their 
size and complexity.  But both of them have pretty good books 
about them available:

Chris and some other people here dislike Google Groups and 
try to imply that everyone here feels the same way.  Not true.

I and many other people here use Google Groups and have been 
doing so for years so if Google Groups works for you, please
feel free to continue using it.

Development versions which support Python 3 are available here 
http://wxpython.org/Phoenix/snapshot-builds/  Unfortunately they've not 
been updated since 3rd December.  I've asked why and been told that 
Robin Dunn is simply too busy.  There's Open Source for you :)

Of course I dislike Google Groups, users keep sending double spaced crap 
which I don't want to see.  There is no "noise level" from people like 
Chris, which obviously includes me.  There is a constant stream of 
polite requests not to send double spaced crap which we do not wish to 
see.  There are at least two solutions to this, follow the instructions 
in the link repeated above for the umpteenth time or use a different tool.

Just to be clear, PyQt does not provide the drag and drop form designer.
That comes from QtDesigner or QtCreator, which is part of Qt itself and
you can use it to design GUIs for use in any language that Qt has
bindings for, not just Python.  PyQt probably does come with a code
generator to convert the xml GUI definitions into Python, but these days
such use is discouraged in favor of using Qt itself to load the XML file
at runtime and build the objects on the fly for you.  It's way more
flexible and there's no code generation needed.  (Apple has done this
for years with Cocoa with their nib files in the bundle.)

Yes there are concepts you'll have to wrap your brain around such as how
to do proper widget layout.  Things aren't placed in a fixed way
usually.  They are allowed to grow and shrink with the window size.  And
you will have to grasp how events work.

Of all the APIs I've used, I think GTK in Python is the cleanest (PyGTK
or PyObject).  But if I was targeting Windows or Mac I'd stick with
PySides/PyQt.

It depends on what you want to do with the GUI, since there are many
different GUI frameworks for Python.

E.g. If you absolutely need to run your applications on MacOS X, then
PyGTK is probably not the best choice. WingIDE, a popular IDE, has been
recently ported to PyQt, apparently for this reason. Besides, PyGTK
itself seems to be "shelved", PyGObject now (since GTK 3) seems to be
the "canonical" way to implement GTK GUIs in Python.

Tkinter is a bit "special" to use since it's not just a library, but
uses some kind of RPC. It seems that "look and feel" have been greatly
improved lately.

wxWidgets (wxPython) recently (since 2.9/3.0) got support for Cocoa,
it's native on the Mac. It's quite slim, but seems to be a "moving
target" API-wise, since the developers are not shy from breaking
compatibility. Is it compatible with Python 3 yet?

PyQt looks native everywhere, but it might be a bit overweight,
depending on what you want to do and where your applications need to
run.

And then there's the licensing issue, since PyQt, unlike Qt itself, is
not available under LGPL afaik. For closed-source commercial
applications, there seems to be a way to use a commercially licensed
PyQt (much less expensive than Qt itself) together with LGPL-Qt
however. Pyside would be a LGPL alternative to PyQt, but it doesn't
seem to be as up-to-date as PyQt.

And then, there are even more frameworks, such as Pygame, PyGUI, etc....

And each of these frameworks has dedicated mailinglists.

Personally I found it difficult to use any of the "wrapped" C++
frameworks without being able to understand the documentation made
for C++. :-(

Sincerely,

Wolfgang

I know Tkinter originated with the Tcl/Tk language.  With Tkinter in
Python is it still using Tcl/Tk under the hood?  IE embeds the Tcl
language interpreter into Python's interpreter?  If so I've always found
it a bit strange that the de facto GUI library that's shipped with
Python ships an entirely different language with it under the hood.

That's just the "Interpreter" design pattern, except the Domain Specific 
Language is already written for you :-)

(I'm half-serious here.)

But more seriously, 100% seriously in fact, I think that you'll find that 
*every* GUI framework for Python ships with an entirely different 
language under the hood, usually C. Even if the top level of the 
framework is written in Python, the underlying graphics routines used for 
drawing controls and windows will surely not be. Given that the actual 
maintenance of the GUI itself is unlikely to be a bottleneck in any real 
application, I don't think it is a significant problem efficiency-wise 
that Python tkinter relies on an intermediate framework written in Tcl.

You seem to be equating "was compiled from" with "includes an
implemenation of".  Do you say that CPython "ships with C"?

Er, all of them? I daresay that Tcl itself eventually calls graphics 
routines written in C. There's not that many languages that commonly get 
used for low-level graphics routines, but C is one of them.

If you mean, ships with a C *compiler*, or even a C interpreter, then no, 
probably not. But it wouldn't surprise me if some of those GUI frameworks 
are powerful enough to count as mini-languages in their own right.

Well, when you take my comments out of their context, that does seem to 
be a totally stupid thing to say. But in context, it's only *mostly* 
stupid, and mostly stupid means a little bit sensible *wink*

The context was a complaint, or at least expression of surprise, that 
Python use Tcl for a GUI, this being contrasted with (paraphrasing the 
legions of people who have expressed surprise about this in the past) 
"some hypothetical GUI written in Python". But in practice, it won't be 
written in Python, it will be likely written in C or some other low-level 
language with some interface to Python. The main difference between this 
hypothetical "Python GUI" and Tcl is that Tcl is a Turing-complete 
interpreter which lives in it's own process. 

[Aside: I wonder how many other GUI toolkits are Turing complete?]

As I stated earlier, this is just the Interpreter design pattern, with 
the minor complication that the domain specific language happens to be an 
existing language, Tcl, with an interpreter that usually runs in a 
separate process, instead of some mini-language running inside Python.

So I don't see anything surprising about Tkinter (or for that matter, 
Ruby and it's bindings to Tcl/Tk). Maybe it's because I'm used to Unix/
Linux systems, where it is common for tools that execute in one 
interpreter to call other tools which execute in a different interpreter. 
E.g. a shell script which calls a Ruby script which calls some command 
which happens to be written in Python. Python, after all, was originally 
invented to be a glue language, and I don't really see anything weird 
about Python delegating work to Tcl any more than I see anything strange 
about IronPython delegating work to the .Net runtime.

Yeah, but there's a difference between passing your GUI incantations
on to a library function (written in C but now just part of a binary
library) and feeding them to a completely different language
interpreter. When I write something with PyGTK, I can't, even in
theory, give it arbitrary C code to execute. From what I understand
here, that *is* true of Tcl, which means that the Python download
contains a Python interpreter and a Tcl interpreter. I'm not saying
that's a bad thing to do, but it is calculated to provoke remark.

Yes, a Tkinter app has both a Python interpreter and an underlying Tcl 
interpreter. Let's be clear about that.

The technical reason for this is that, during Python's early 
development, Tk was the simplest, most powerful and OSS-friendly GUI 
toolkit out there (compared to, let's say, Motif). Its reliance on Tcl 
was a plus because Tcl's C API is exceptionally clean and easy to 
embed/call from other C libraries (that was Tcl's original main focus, 
embedding in C).

Embedding the Tcl interpreter remains a sound decision today. It makes 
it trivial to keep Tkinter updated in sync with Tk updates, since the 
Tcl interpreter does most of the heavy lifting. The recent effort to 
wrap Tk's new themed widgets is a good one: nearly all of the work was 
done at the Python level. Compare this approach to Perl's original one, 
which stripped out Tcl and implemented Tk integration entirely in C. Any 
updates require heavy lifting in C and, in fact, Perl/Tk has not kept up 
with Tk's main line of development (it does not run natively on the Mac, 
for instance).

Calling through Tkinter to Tcl also provides some other conveniences. If 
you're writing a Tkinter app and want to access some platform-specific 
functionality that requires C calls, that may require a library 
extension written against Tcl/Tk's C API (i.e. the Mac's NSServices 
API--that can't be accessed using ctypes because it hooks into the 
window server). Fortunately, Tk is very easy to extend in C--much 
simpler than extending wxWidgets or Qt.

Finally, Tcl is itself a fully-featured, general programming language 
that is a peer to Python both generationally and in terms of its 
capabilities; the main way it lags is in the size of its development 
community. In other words, you are not handing the ball off to a 
90-pound weakling if you need to call into Tcl from Python via Tkinter. ;-)

Having made a tweak to gitk at one point, I have to say Tcl is
definitely inferior to Python. I'd much rather work with Python
itself. :)

Without starting a flame war, can you elaborate? I'm curious about your

Here's the Tcl procedure that I tweaked. This is from gitk; I find the
word diff not all that useful, but a character diff at times is very
useful. I haven't found a way to configure the word diff regex through
gitk's options, so I tweaked it in the source code.

proc getblobdiffs {ids} {
    global blobdifffd diffids env
    global diffinhdr treediffs
    global diffcontext
    global ignorespace
    global worddiff
    global limitdiffs vfilelimit curview
    global diffencoding targetline diffnparents
    global git_version currdiffsubmod

    set textconv {}
    if {[package vcompare $git_version "1.6.1"] >= 0} {
        set textconv "--textconv"
    }
    set submodule {}
    if {[package vcompare $git_version "1.6.6"] >= 0} {
        set submodule "--submodule"
    }
    set cmd [diffcmd $ids "-p $textconv $submodule  -C --cc
--no-commit-id -U$diffcontext"]
    if {$ignorespace} {
        append cmd " -w"
    }
    if {$worddiff ne [mc "Line diff"]} {
        append cmd " --word-diff=porcelain --word-diff-regex=."
    }
    if {$limitdiffs && $vfilelimit($curview) ne {}} {
        set cmd [concat $cmd -- $vfilelimit($curview)]
    }
    if {[catch {set bdf [open $cmd r]} err]} {
        error_popup [mc "Error getting diffs: %s" $err]
        return
    }
    set targetline {}
    set diffnparents 0
    set diffinhdr 0
    set diffencoding [get_path_encoding {}]
    fconfigure $bdf -blocking 0 -encoding binary -eofchar {}
    set blobdifffd($ids) $bdf
    set currdiffsubmod ""
    filerun $bdf [list getblobdiffline $bdf $diffids]
}

First off, everything's done with commands, rather than assignment
("set diffinhdr 0"), which is very shell-style and not very
programming-style. Can live with that, though even shells can use
equals signs for simplicity. Similarly, the shell style of adorning
variable usage feels messy. There are string literals, some of which
contain interpolated variables; there are dollar-sign adorned
variables; and then there are other words. What are the other words?
Are they implicit strings (as they would be in, say, bash)? I've never
really liked that style. Anyway. Can get past that.

Secondly, what does this do?
    if {$worddiff ne [mc "Line diff"]}

I *think* it means 'if $worddiff is not equal to "Line diff" (this
code is executed for the options "Markup words" and "Color words", but
what's the mc do? How am I supposed to figure out what it does? Where
do I begin to look?

This is where, IMO, Python tends to be a lot clearer. It's easy to see
what's an object and what's a method on it, and every bare word is
either a local name or a standard built-in name. I'm sure Tcl's a
great language, but I'd rather not have to drop out of Python into it
if I can help it. :)

I wrote a few Tcl apps once many, many years ago.  After attempting to
write something more than a few hundred lines long, I gave up and
swore off Tcl completely.  I switched to Scheme, and later to Python.

The things I found infuriating about Tcl:

  * The "everything is a string" view of the world is severly
    limiting if you're not just processing strings.

  * The quoting syntax and semantics appears to have been invented by
    somebody at the CIA as a way to torture programmers into doing...
    something... I don't know what.

  * Tcl doesn't seem to have any sort of coherent design or philosophy
    behind it but rather consists of a bunch of hacks piled on top of
    a simple and limited shell-like string processing language.  It
    sort of feels like PHP in that regard.

When I finally gave up fighting with Tcl's quoting semantics half way
through a medium/small application and switched to Scheme/Tk, I had my
app written from scratch in a fraction of the time it took to get
about half way done in Tcl, and with about 1/3 the lines of code.

Python probably would have cut both hours and lines by half again
compared to Scheme.

There are arrays with string keys (similar to Python dictionaries).
