String multi-replace
Hi All,
I have to eliminate diacritics in a fairly large file.
Inspired by http://code.activestate.com/recipes/81330/, I came up with the
following code:
#! /usr/bin/env python
import re
nodia={chr(196)+chr(130):'A', # mamaliga
chr(195)+chr(130):'A', # A^
chr(195)+chr(142):'I', # I^
chr(195)+chr(150):'O', # OE
chr(195)+chr(156):'U', # UE
chr(195)+chr(139):'A', # AE
chr(197)+chr(158):'S',
chr(197)+chr(162):'T',
chr(196)+chr(131):'a', # mamaliga
chr(195)+chr(162):'a', # a^
chr(195)+chr(174):'i', # i^
chr(195)+chr(182):'o', # oe
chr(195)+chr(188):'u', # ue
chr(195)+chr(164):'a', # ae
chr(197)+chr(159):'s',
chr(197)+chr(163):'t'
}
name=R\xc3\xa2\xc5\x9fca
regex = re.compile((%s) % |.join(map(re.escape, nodia.keys(
print regex.sub(lambda mo: dict[mo.string[mo.start():mo.end()]], name)
But it won't work; I end up with:
Traceback (most recent call last):
File multirep.py, line 25, in module
print regex.sub(lambda mo: dict[mo.string[mo.start():mo.end()]], name)
File multirep.py, line 25, in lambda
print regex.sub(lambda mo: dict[mo.string[mo.start():mo.end()]], name)
TypeError: 'type' object is not subscriptable
What am I doing wrong?
Thanks for your advice,
SxN

Re: String multi-replace
Thanks for your answers. Benjamin Kaplan: of course dict is a type... silly me! I'll blame it on the time (it's midnight here). Chris Rebert: I'll have a look. Thank you both, SxN -- http://mail.python.org/mailman/listinfo/python-list
Re: String multi-replace
Steven D'Aprano: the original file is 139MB (that's the typical size for it). Eliminating diacritics is just a little toping on the cake; the processing is something else. Thanks anyway for your suggestion, SxN PS Perhaps I should have mention that I'm on Python 2.7 -- http://mail.python.org/mailman/listinfo/python-list
Autocompletion
Hi All, Does anybody knows about a module to assist with text autocompletion for a given dictionary? Thanks, SxN __ Ask a question on any topic and get answers from real people. Go to Yahoo!

Re: Autocompletion
Sorry for being careless in my choice of words: when I wrote dictionary, I meant a collection of words in any given human language, not a Python dictionary. Perhaps I should try to explain a bit more what I try to accomplish: in a notebook the user will write text, and certain words (collected in a, let's say, vocabulary) need this feature. Ideally, I'd like to start the autocompletion feature when the widget gets the focus, and stop it when focus is lost. Moreover, when starting, a numeric parameter should dictate that the autocompletion will kick in after writing the respective number of characters. I said notebook because that's my intended use, but any kind of text entry should have the same behaviour if autocompletion is associated with it. I am targeting an English and a French vocabulary.

Re: Some test fail on my new Python 2.6
Thanks for the pointers. Here are some answers: Ok, so DBM wasn't built because it couldn't find the external symbol 'dbm_firstkey'. I have no idea off the top of my head why that would happen, but I don't think you really care at the moment since you are trying to get tkinter working. If you do care we can come back to that. Although I can live without it, I do use sometime dbm.

Re: Some test fail on my new Python 2.6
Hello again, /usr/local/lib is in /etc/ld.so.conf. The files are real. However, creating symlinks in /usr/lib targeting the libraries in /usr/local/lib, then recompiling, solved the tkinter problem. So, the conclusion is that only /usr/lib is consulted for the tcl/tk libraries. multiprocessing - do I need it? Probably not. I can fork() a new process, so I can manage. I don't know what am I loosing without multiprocessing. socket was solved as suggested, by adding the host name in /etc/hosts, like this: 127.0.0.1 localhost dsr-1 sys doesn't fail anymore after recompilation (have no clue why). htttpservers is still failing the same. Everything is done as root. I'll move on with make install. Thanks for your help; I'm progressing :-) SxN __ Instant Messaging, free SMS, sharing photos and more... Try the new Yahoo!

Re: Some test fail on my new Python 2.6
Run 'make test' instead of running them one by one. I did it *before* going one by one. I then tried individual tests in hope of getting hints of what to look for. Actualy, for the first three tests, the make test script commented that it is unusual for them to fail on my platform (linux2). SxN __ Instant Messaging, free SMS, sharing photos and more...

Re: Function stopping a function
In my situation, there is a device with keyboard that allows some user input. In the same time, the device is connected to a standard PC, and there may be some communication there. The lengthy_function() resides and executes in the device, and so is cancel(). Lengthy_function() is pretty linear: according to some conditions, the user is asked for this or that. Than, with the new conditions, lenghty_function() may need to communicate with the PC. And now, with the updated conditions, may ask more stuff from user. At any time the user can press a CANCEL button, or the PC can generate a CANCEL. What I have now is a global variable which cancel() will change and then, each if statement in lenghty_function() will check that variable, together with its specific condition. I was hopping that there may be a more elegant solution. No threads involved in my design (apart for what the device may have to handle events like button-press and serial communication).

Function stopping a function
Hi All, We all know that a function can launch the execution of another function. How can a function stop the execution of another function? For instance, lenghty_function() executes, when an external event triggers cancel(), which is supposed to abruptly stop lengthy_function(), reset some variables and exit immediately.

Enter Enter... troubles
Hi All,
In my application I have a class like this:
from Tkinter import *
class MyClass:
def __init__(self, root):
self.property=value
self.aButton=Button(root, text='Press me!')
self.aButton.bind('Return', self.handler)
self.aButton.bind('KP_Enter',self.handler)
...
def handler(self,event):
self.aButton.unbind('Return')
self.aButton.unbind('KP_Enter')
...
localVar=self.property
self.property=newCalculatedValue
...
self.aButton.bind('Return', self.handler)
self.aButton.bind('KP_Enter',self.handler)
The idea is to prevent a fast user (like my boss) to press repeatedly the
enter
key and create havoc with self.property and localVar. But it doesn't work: my
boss manages to start at least twice the handler (which, among other things
creates a Toplevel, so I end up with a messy screen).
How should I proceed?
Thanks for your advices,
Sorin

Python 2.5 install on Gentoo Linux: failed dmb and _tkinter
Hi All, After a disaster in which I lost my whole harddrive, I decided to install the newest everything that I use. I put the latest Gentoo Linux, with gcc 4.1.1, installed tcl/tk 8.4.14 and tried Python 2.5. I tried with and without the suggested -fwrapv compiler option, and make gave me the same: code # make case $MAKEFLAGS in \ *-s*) CC='gcc -pthread -fwrapv' LDSHARED='gcc -pthread -fwrapv -shared' OPT='-DNDEBUG -g -O3 -Wall -Wstrict-prototypes' ./python -E ./setup.py -q build;; \ *) CC='gcc -pthread -fwrapv' LDSHARED='gcc -pthread -fwrapv -shared' OPT='-DNDEBUG -g -O3 -Wall -Wstrict-prototypes' ./python -E ./setup.py build;; \ esac running build running build_ext db.h: found (4, 2) in /usr/include db lib: using (4, 2) db-4.2 building 'dbm' extension gcc -pthread -fwrapv -fPIC -fno-strict-aliasing -DNDEBUG -g -O3 -Wall -Wstrict-prototypes -DHAVE_GDBM_NDBM_H -I. -I/plus/install/Python-2.5/./Include -I./Include -I. -I/usr/local/include -I/plus/install/Python-2.5/Include -I/plus/install/Python-2.5 -c /plus/install/Python-2.5/Modules/dbmmodule.c -o build/temp.linux-i686-2.5/plus/install/Python-2.5/Modules/dbmmodule.o gcc -pthread -fwrapv -shared build/temp.linux-i686-2.5/plus/install/Python-2.5/Modules/dbmmodule.o -L/usr/local/lib -lgdbm -o build/lib.linux-i686-2.5/dbm.so *** WARNING: renaming dbm since importing it failed: build/lib.linux-i686-2.5/dbm.so: undefined symbol: dbm_firstkey building '_tkinter' extension gcc -pthread -fwrapv -fPIC -fno-strict-aliasing -DNDEBUG -g -O3 -Wall -Wstrict-prototypes -DWITH_APPINIT=1 -I/usr/X11R6/include -I. -I/plus/install/Python-2.5/./Include -I./Include -I. -I/usr/local/include -I/plus/install/Python-2.5/Include -I/plus/install/Python-2.5 -c /plus/install/Python-2.5/Modules/_tkinter.c -o build/temp.linux-i686-2.5/plus/install/Python-2.5/Modules/_tkinter.o gcc -pthread -fwrapv -fPIC -fno-strict-aliasing -DNDEBUG -g -O3 -Wall -Wstrict-prototypes -DWITH_APPINIT=1 -I/usr/X11R6/include -I. -I/plus/install/Python-2.5/./Include -I./Include -I. -I/usr/local/include -I/plus/install/Python-2.5/Include -I/plus/install/Python-2.5 -c /plus/install/Python-2.5/Modules/tkappinit.c -o build/temp.linux-i686-2.5/plus/install/Python-2.5/Modules/tkappinit.o gcc -pthread -fwrapv -shared build/temp.linux-i686-2.5/plus/install/Python-2.5/Modules/_tkinter.o build/temp.linux-i686-2.5/plus/install/Python-2.5/Modules/tkappinit.o -L/usr/X11R6/lib64 -L/usr/X11R6/lib -L/usr/local/lib -ltk8.4 -ltcl8.4 -lX11 -o build/lib.linux-i686-2.5/_tkinter.so *** WARNING: renaming _tkinter since importing it failed: libtk8.4.so: cannot open shared object file: No such file or directory running build_scripts /code I have libtk: code # ls -l /usr/local/lib/libtk8.4.so -r-xr-xr-x 1 root root 906285 Jan 10 16:08 /usr/local/lib/libtk8.4.so /code I can start wish.

(the quote is from 'Le gendarme et les extra-terrestres', a must-see Frech comedy)Hi All,I'm trying to use the smtplib - I did it so many times already. The import statement fails, as theSMTP name cannot be imported. Digging more, I found that SMTP fails becauseemail.base64MIME cannot be imported (ImportError:No module named base64MIME).I don't understand why, as the file is in the right location, has the correct access rights (I'm onLinux), and it's content is not corrupt. I also tried to import email.__init__ and end up with the same error.The only way that works is to navigate to the email directory and perform the import base64MIME there.What may have happened?Thanks,Sorin-- http://mail.python.org/mailman/listinfo/python-list

Tkinter question
Thanks for everybody's advice, on both forums (tkinter-discuss python-list).I end up using Fredrik's Lundh solution, since, in my project, multiple buttons are using the same callback, and their creation is controlled by the interaction with the user.Thanks again,Sorin-- http://mail.python.org/mailman/listinfo/python-list
Tkinter question
Hi All,Is it possible to have a widget id while it is created?Something like this:Button(root, text='...', command= lambda v=widget id: fn(v)).grid()and then the function:def fn(v): v['bg']='BLUE' # or maybe nametowidget(v)['bg']='BLUE'Thanks,Sorin-- http://mail.python.org/mailman/listinfo/python-list
overrideredirect and Text widget
Hi again,Last afternoon I posted a question regarding the loss of keyboard in an undecorated window. Last night I tried again, at home, and the same code worked fine. The difference: it failed under (Gentoo) Linux, it succeeded under Win 2000, both running Python 2.4.x.So, I guess, my question now is how to achieve the desired behaviour under Linux?Thanks for your advice,Sorin-- http://mail.python.org/mailman/listinfo/python-list

overrideredirect and Text widget
Hi,I'm trying to place in an undecorated window a Text widget, and a button to close the window/save widget's content. My test code is the following:codefrom Tkinter import *root=Tk()root['bg']='' # transparent backgroundroot.overrideredirect(1) # get rid of borderroot.geometry("+80+120") # place on screenroot.focus_set() # take focusbt=Button(text="End",command=root.quit)bt.grid(row=0, stick=E) # a button to allow window's closuretx=Text(bg='white',height=3)tx.grid() # a text widgettx.focus() # give focus to textroot.mainloop()/codeOn my machine it doesn't give focus to Text. Any advice?Thanks,Sorin--

Tkinter listbox:get
lb.curselection() won't return an integer, but a tuple of strings. Also, a StringVar receives a new value with the set() method. So, you'll have to write something like:idx=lb.curselection()StringValue.set(lb.get(int(idx[0])))This will grab the first value from the tuple, convert it in integer, and pass it to lb.get() to extract the line in your Listbox, and set it in your Entry via the StringVar. If you allow multiple selections from your Listbox, you may have more than one value in idx, and you'll have to decide how you intend to process them.Check any of these (or both):http://www.pythonware.com/library/tkinter/introduction/index.htmhttp://infohost.nmt.edu/tcc/help/pubs/tkinter/They're both easy to follow, and you'll save more time, than asking one little think at a time, and then waiting for someone to answer.Good luck!Sorin-- http://mail.python.org/mailman/listinfo/python-list
rollover effect
Hi,
For the right-click event, you should use a bind to
Button-3. If you have a new version of Python,
chances are that you already have Tix installed. Tix,
like Pmw, is an extension package for Tkinter, and it
also offers a Balloon widget.
See the following example:
code
from Tix import *
r=Tk()
l=Label(r,text='This is my label')
def fn(e):
global l
print 'Right clicked :-)'
l.bind('Button-3',fn)
l.grid()
b=Balloon(r)
b.bind_widget(l,balloonmsg='text in balloon')
r.mainloop()
/code
If you're a beginer, than you may want to have a look

extensions:

How to let a loop run for a while before checking for break condition?
to Fredrik Lundh I'm afraid Claudio Grondi can't use your solution, as he needs it hosted on Windows, which lacks signal.alarm. to Claudio Grondi How about splitting your loop in two? The first loop would check for your boolean, which is changed by your timer, the second loop will check for your normal exit condition? Sorin __ Do You Yahoo!? Tired of spam? Yahoo!

How to let a loop run for a while before checking for break condition?
I am thinking on something in the following form: code import time import thread delay=True def fn() global delay time.sleep(your_amount_of_time_in_seconds) delay=False thread.start_new_thread(fn,()) while delay: statement 1 statement 2 ... while other_condition: statement 1 statement 2 ... /code Or, if you need to use break, the second loop may be something like: code while True: statement 1 statement 2 ... if other_condition: break other_statements ... /code The two while loops have the same content, but the first is terminated after a pre-determined amount of time, while the second by another condition. Usually the content of the too loops, being the same, is a call to a function that does the actual work. In your case, as time seems to be critical, you don't want to spend it in function-call overheads, so you repeat (cut'n'paste) the relevant code. Of course, the price to be paid is in maintenance headache: you'll have to make all the changes in both loops, to keep consistency. I hope this helps. Sorin __ Do You Yahoo!? Tired of spam? Yahoo!

signal - no update 'til I move the mouse
Hi, My project needs to allow some inter-process communication. That one is solved, and when an answer is sent, it goes to its destination via a signal. Then, the Tkinter screen needs to be updated, so the user can take the next action. On my laptop it works instantly, on my desktop, only after I move the mouse inside my application's window. Configurations: Laptop: Dell Latitude C600, Gentoo Linux, kernel 2.6.11, Python 2.4.1, KDE 3.3.x Desktop: IBM NetVista, Gentoo Linux, kernel 2.6.11, Python 2.4.2, KDE 3.4.x I am pretty sure that's not a Tkinter related issue, since I tested some print statements and they behave in a similar way, but what can it be?

Tkinter's createfilehandler - attempt to run parallel threads
Hi,The project that I'm working for runs a PostgreSQL database on a remote machine and several Python clients all over the place. The objects usualy have in their constructor a query to the database. As the query is executed on the remote machine, I'm trying to be fancy and execute it while building my Tkinter interface.The following code illustrates what I'm attempting to do:code#! /usr/bin/pythonfrom pg import DBfrom Tkinter import *class thrd: def __init__(s,r): print 'Executing __init__' db=DB('design',host='xx.xx.xx.xx',user='') # relevant IP and user needed print 'db=DB(...' tkinter.createfilehandler(db,tkinter.READABLE|tkinter.WRITABLE,s.th) print 'createfile...' Label(r,text='Let\'s see the results').grid() print 'Label...'
s.b=Button(r,text='GO') print 's.b=Button...' s.b.bind('Button-1',s.rslt) print 's.b.bind...' s.b.grid() print 's.b.grid()' print '__init__ done' def th(s,db,msk): print '-Executing th' s.r=db.query('select * from customers limit 10').getresult() # some query print '-s.r=...' tkinter.deletefilehandler(db) print '-deletefile...' db.close() print '-db.close()' print '-th done' def rslt(s,e): for i in s.r: print iif __name__=='__main__': r=Tk() t=thrd(r) r.mainloop()/codeThe output is:Executing
__init__codedb=DB(...createfile...Label...s.b=Button...s.b.bind...s.b.grid()__init__ done-Executing th-s.r=...-deletefile...-db.close()-th done/codeand it basicly shows that everything happens sequentialy. Pressing the button gives the expected result, so everything is correct. How can I obtain the desired parallelism?Thanks,Sorin

Tix Tree open/close issue
Hi,
I tried for the first time a Tix Tree, so, if my
question is naive, I apologize upfront.
The following code:
code
from Tix import *
r=Tk()
tr=Tree(r)
tr.subwidget('hlist').add('br1',text='branch 1')
tr.subwidget('hlist').add('br1.b1',text='branch 1-1')
tr.subwidget('hlist').add('br1.b1.b1',text='branch
1-1-1')
tr.subwidget('hlist').add('br1.b1.b2',text='branch
1-1-2')
tr.subwidget('hlist').add('br1.b2',text='branch 1-2')
tr.subwidget('hlist').add('br1.b2.b1',text='branch
1-2-1')
tr.subwidget('hlist').add('br1.b2.b2',text='branch
1-2-2')
r.tk.call(tr,'setmode','br1','close')
r.tk.call(tr,'setmode','br1.b1','open')
r.tk.call(tr,'setmode','br1.b2','open')
#tr.setmode('br1','close')
#tr.setmode('br1.b1','open')
#tr.setmode('br1.b2','open')
tr.grid()
r.mainloop()
/code
will show the whole tree, but will set correctly the
(+) and (-) boxes. (The commented out statements where
in place before direct calls to Tk - same result).
I was hoping to have some branches hidden (the leaves,
in this case).
How should I proceed?
Thanks,
Sorin

Tkinter, grid, in_: widget definition order significant ?!
Hi,Working on my current project, I discovered the following behaviour: a widget defined before the window in which I try to grid it won't show up, but will take space and behave like it is there (blind typing proves it). A widget defined after the griding window will come up fine. The following example illustrates my point:codefrom Tkinter import *r=Tk()l1=Label(r, text='first label')f=Frame(r)f.grid()l1.grid(in_=f, row=0)l2=Label(r, text='second label')l2.grid(in_=f, row=1)/codeOn my system (Gentoo Linux, Python 2.4.1) l1 (defined before f) takes spaces, but is invisible, while l2 (defined after f) is OK.That's the way it is intended to be? How would I grid stuff in dynamically created windows?Thanks for your advice,Sorin Schwimmer How low will we go? Check out Yahoo!
