Hello all,
I have two thing I wish to accomplish, First, put an icon in a gtk.Entry as in
many search boxes. Second put a gtk.Checkbox in a gtk.ComboboxEntry. On the
later I thought I could get a handle to the Combobox tree and then add a column
and then column span column 1 back into column
I have a goal function that returns the fitness of a given solution. I
need to wrap that function with a class or a function to keep track of
the best solution I encounter. Which of the following would best serve
my purpose and be the most pythonic?
class Goal:
def __init__(self, goal):

I have run into a bit of a subtle problem. How do I go about
duplicating a variable (particularly a list of lists) in python. I
was surprised when simple assignment didn't work. For example, let y =
[1,2,3]
>>> x = y
>>> x[2] = 5
>>> y
[1,2,5]
It seems that simply assigning x to y allows furthe

Hello! I am currently working on writing a simulation engine for
special relativity physics. I'm writing it in Python, of course. I'm
doing fine with the engine, but I want a GUI framework in which I
could use it conveniently, and test different setups on it. I'm not so
strong with GUI programming.
print "foo"
print "bar"
has a newline in between "foo" and "bar"
print "foo",
print "bar"
has a space in between "foo" and "bar"
How prevent ANYTHING from going in between "foo" and "bar" ??
(Without defining a string variable.)
