In previous post I asked about turtle module importing from tkinter.
But what I don't understand is why does Tkinter default it's casnvas
to ScrolledCanvas in turtle.py, and then as a 'metaclass' for
ScrolledCanvas in turtle it calls TK.Frame, which could have
been set as a default within Tkinter
Hi Marco (and everybody),
in another thread you showed your code and made extensive use of
property(). Wrongful use I might say.
Let's see an example:
>>> class C(object):
... def __init__(self): self._x = None
... def getx(self): return self._x - 10
... def setx(self, value): self.
Dear Friends,
I'm new to the list, and new to Python. The last time I've tried
anything like the below was 20 years ago on a NeXT machine, and I had
no clue what I was doing then, either.
I've gotten IDLE up and have done some hello worlding.
I am now trying to get the NLTK working on my new iM

What does "still does not work" mean?
Please copy and paste the error you get.

Open an interactive session and
I tried to enter model = Modele (nom_fichier) but it still does not work.
And for the list I don't understand very well, Do you know where I can pay
someone to help with my programming.
Because I feel to annoy tutors with my basic stuff

Hi everybody, I would appreciate your help on this one
In this program I want to create 2 concepts each with 2 or 3 properties
My first concept is magasin(shop in french) and my shop has 3 attributes:
nom(name in french), items and ville (city in french)
the second one is items and its 2 attributes
Hi all,
I have a problem about variables efficiency.
As below, I import f from config.py, Then f is appended to app1.py global
variables.
In class App, there're two ways to use this variable. One is "self.file =f",
then use self.file; the other is using "f" directory. Which way is high
efficient?
