Hi!
Suppose a class C.
I want something like this:
class C:
KA=0
KB=1
KC=1

Kn=n

These constants come from an enum in a .h (header of C file).
They are many and may change from time to time.
Is there a way

Hi all.
Not sure if this is the place to ask about kivy ...
I apologize if not.
I am playing with the example here
https://gist.github.com/geojeff/4442405
Now I would like to change the background color the editable field.
So I added

Hi all.
What is the fastest way to do the following:
I have an initial value V and a vector vec of (financial) indexes.
I want to generate a new vector nvec as
V, V*vec[0], V*vec[0]*vec[1], V*vec[0]*vec[1]*vec[2], ...
A numpy vectorized solution would be better.
Thanks

Thank you very much Oscar and Duncan.

Hi,
Sorry if this is a FAQ, but I have googled and didn't find any
satisfatory answer.
Is there a simple way, preferably multiplataform (or linux), of
generating sinusoidal/square waves sound in python?
Thanks for any answers/suggestions.

Hi!
If I have two files .py such as
m.py

x=c()

os.any_method ...

c.py
class c:
def __init__(self, ...):

Now I understand perfectly how "import" works.

Hi!
What is the best way to have something like the bisect_left
method on a list of lists being the comparision based on an
specified arbitrary i_th element of each list element?
Is there, for lists, something equivalent to the __cmp__ function for
classes?
Thanks.

I think that what you want is numpy.

Hi.
I have just seen that csv module, more exactly the Dialect class,
does not have any variable to specify the "floating point" character!
In portuguese this is ','. Not '.'. 3.1415 -> 3,1415.
I think this is also the case of other languages/countries.
If I am correct, i.e. if there is no such po
