add indexes on the fly to lists
I wanted to make a list index work as the index of the data in the database. something like database: idx item_description item_value being imported to my program as: x[idx][0]= item_description x[idx][1]= item_value the problem is that there will be some hundred items and possible the idx wil vary from 1 to 600 (it's not linear as items got deleted the idx should not be reused) will it still be an easy solution or just a waste of resources (having a 600-sized list for 100 elements) I'm very new to python and apreciate any hints on that. Thanks Gabriel -- http://mail.python.org/mailman/listinfo/python-list
is this use of lists normal?
I just sent an email asking for hints on how to import data into a
python program
As i said earlier i'm really new to python and besides being
confortable with the syntax, i'm not sure if i'm on the right track
with the logic
I'm asking for hints again here at the list because i think i'm
already into premature optimization...
My object model ended up as
DataStorageObj
|-itemsIndex (list, could very well be a set...)
| |-[0] = 0
| |-[1] = 1
| |-[2] = 5
| '-[3] = 6
'-Items (list)
|-[0] = ['cat food', '12,20']
|-[1] = ['dog food', 8,00']
|-[2] = ['dead parrot', '25,00']
'-[3] = ['friendly white bunny', '12,25']
the list itemsindex has the DB index of the data, and the list items
has the data.
So if i want something like "SELECT * FROM items WHERE idx=5" i'd use
in my program
self.items[ self.itemsIndex.index(5) ]
i reccon that's not much nice to use when you're gona do /inserts/ but
my program will just read the entire data and never change it.
Was i better with dictionaries? the tutorial didn't gave me a good
impression on them for custom data...
Tupples? the tutorial mentions one of it's uses 'employee records from
a database' but unfortunatly don't go for it...
i think the 'ideal' data model should be something like
({'id': 0, 'desc': 'dog food', 'price': '12,20'}, ...)
But i have no idea how i'd find some item by the ID within it withouy
using some loops
Thanks!

tk global bindings
I'm starting to write a POS application UI's module. There's no mouse, just a bunch of global shortcuts. the problem is that TK doesn't have global shortcuts! Is there a work-around or i will have to attach 80 or so bindings for every input element? Thanks, Gabriel -- http://mail.python.org/mailman/listinfo/python-list

I'm terrible sorry to extend this topic even furter, but it's silly, not to say dull to think like that. in the first place, it's not that they're doing charity. they have plans. if they release Qt under GPL for non-comercial use, it's because they want to increase the user base and so be able to earn money with the comercial fee later. And if i'm going to write software for it, when there's plenty of alternative that actualy works flawless under windows, why should i stick with an option that i don't even know to wich extends i can use the damn thing?

They claim it's a GPL'ed version, but it's a trolltech license that forces you to release your code under gpl even tought their's not! I'm not against a company getting it's share with their product. that's what motivated them in the first place. but DONT LIE! don't call it gpl when it's not. Gpl make it very explicity it deals with the program as a whole, in the meaning of a executable code. What they're trying to achive here is that, by adding this paragraph, they will cover the "dll use" under the gpl. By that cover-all definition they came up, i can't use Internet Explorer to see a site hosted with a gpl'ed server! i can't even use a BSD program to grep a file! anyway... it will only mater when people with money cares.

tcl/tk naming scheme vs python's
I got my self writting nested objects to hold Tk references, then i realizes that i was working in python and not tcl, so i switched to flat vars... and in no time i was using more then 7 words separated by captalization in the names... i was able to rethink my scheme to use 5... no less. i'm i exagerating or do you people also comes to this some times? The other choice i think i had was to use semantic names instead of semantic and hierarchical ones.

tk resource file for geometry?
i'm using almost every widget property from my pyTk programs in the form of resources, like: self.tk.option_add ( "*InputClass*background", "White" ) In the widget creation i have only the Class and the Command attribute, but i'm having to add some tk options to the geometry method, in the case, pack. Is there a way to overcome this? For example, every single Frame i pack i use self.pack(fill='both', expand=1) I'd love to have something like: self.tk.option_add ( "*Frame*fill", 'both' ) self.tk.option_add ( "*Frame*expand", 'yes' ) Is there anything like it? Thanks, -- http://mail.python.org/mailman/listinfo/python-list
Why Tk treat F10, F11, F12 diferently from F1...F9?
This is completely odd to me...
# Bind F1...F12 to <>
self.tk.event_add( '<>', # keys used to switch between the tabs
'','','','','',
'','','','','',
'',''
)
self.master.bind_all('<>', self.__functionKeysPressed )
def __functionKeysPressed(self, event):
print event.keysym
Now, i run the program and press from F1 to F12, and i get:
F1
F2
F3
F4
F5
F6
F7
F8
F9
L1
L2
F10 simply does nothing!
F11 prints L1
F12 prints L2
The only place google takes is not very elucidating :)
http://64.233.161.104/search?q=cache:t2CnLTHob0sJ:stuff.mit.edu/afs/sipb/project/tcl/linuxbin/dpwish+tk+bind+F12%7CF11+L1%7CL2&hl=fr
Anyone has any ideia why is that?
I surely didn't mind about this if it wasn't for F10 showing nothing.
I get the return code just to use the same function (and same biding)
for the 12 buttons since i can't pass arguments to the Command option
in tk. ...And i'm already considering adding a L1 and L2 check instead
of F11 and F12 and a 'empty' check for the F10... But that would be
plain ugly.
Thanks,
Gabriel

That was it. thanks.
For the record:
The virtual bidings with <> doesn't work. You have to manually
specify the . Seems like a bugged behaviour to me. Or at least,
just very odd and intuitive.

i'm on windowsXP (what makes the F10 biding by "default" even more
weird). Well, for now using the keysym_num will be more safe since i'm
still getting they correct.

simple input that can understand special keys?
i'm writting an application that will use Tinker in a newer future. Now it's console only. I simply ommit some data on the display, print() some other and go on. The problem is that i can't test the actions tiggered by special keys, like Page Up/Down or the F1...12 Right now i'm using raw_input() since even the Tk version will have only one input place, and for debuging i'm literally writting pageup, pagedow and the F's. But i want to put it in test while i write the GUI. is there any hope for me? I wanted to stay only with the console for now.

How about a pickle hook?
You'd just unpack the pickle data, and end up with a pointer to a
frame(?) containing all the goods, then just .pack() it into whatever
you want.

warning for google api users
the google webservices (aka google API) is not even close for any kind of real use yet if you search for the same term 10 times, you get 3 mixed totals. 2 mixed result order. and one or two "502 bad gateway" i did an extensive match agains the API and the regular search service. the most average set of results: results 1-10; total: 373000 results 11-20; total: 151000 results 21-30; total: 151000 results 31-40; total: 373000 results 41-50; total: 373000 results 51-60; total: 373000 results 61-70; total: 151000 ( 502 bad gateway. retry) results 71-80; total: 373000 results 81-90; total: 151000 ( 502 bad gateway. retry) results 91-100; total: 373000 on the regular google search, total: 2,050,000 (for every page, of course) besides that, the first and third result on the regular google search, does not apear in the 100 results from the API in this query, but this is not average, more like 1 chance in 10 :-/ So, no matter how much google insists that this parrot is sleeping, it's simply dead. now, what i presume that is happening, is that they have a dozen of machine pools, and each one has a broken snapshot of the production index (probably they have some process to import the index and or it explode in some point or they simply kill it after some time). and they obviously don't run that process very often.

scope acting weird
i have the following code: Ui.py: import Tkinter as Tk import UiMainScreen UiMainScreen.py: class UiMainScreen( Tk.Frame ): and i get the following error: File "UiMainScreen.py", line 1, in ? class UiMainScreen(Tk.Frame): NameError: name 'Tk' is not defined isn't Tk supposed to be imported globaly?
