Hello all,
I know Python reasonably well, but I still run into basic questions
which those over on the other python list request I post here instead.
I figure this would be one of them:
Why would this not work:

self.arg1=arg1
self.arg2=arg2

Hello all,
I have a 2d list being used for a battleship game. I have structured
the program so that it uses a grid class, which implements this array
along with a bunch of other methods and vars. For example, to get at
the top left square, you would say:
Grid.getSquareAt(0,0)
and inside getSquareAt

Thanks for all the explanations, everyone. This does make sense, and I

In Battleship, I have a weapons.py file, currently with just one

a getImpactCoords method, which returns all coordinates on the map

While Battleship is not quite where I want it in terms of weapons, and

Hi all,
I am having problems with the Durus package, and I was told that
changing Python versions might help. Most of the other dependencies of
the project I have are 2.6 only, so I do not want to change versions

Hi all,
I am wondering if there is a python package that will find
permutations? For example, if I have (1, 2, 3), the possibilities I
want are:
12
13
23
123
132
231
Order does not matter; 21 is the same as 12, but no numbers can
repeat. If no package exists, does someone have a hint as to how to
respond to this email to keep it in the same
thread. Thanks again! Oh, to the person who asked, I have 2.6 and 2.7
installed, with the default being 2.6.

Is there a better way of doing this that would avoid me having to
write the function?

Thanks again to all!

Hi all,
I am reading the source of a project I hope to help with
(http://www.qwitter-client.net). I sometimes see something like:
val=val or 1
I am guessing that val is an int. If val==0, the 'or' kicks in and
val=1, else the or is not needed and val=val. Am I close? Can other
words or symbols be u
Thanks to all for the quick responses. Python always surprises me with
its shortcuts...

Hi all,
I was googling a way to do something like
mydict=mydict.extend(additionaldict)
and someone on a forum recommends this:
mydict=dict(mydict, **additionaldict)
What is the ** doing here? I tried to look it up, but Google seems to
ignore it since it is punctuation. The poster on the forum says
Thanks all! I thought update() would add an item even if it would be a
duplicate, but apparently not. I also now better understand why I am
always passing around *args and **kwargs when calling super(). Very
interesting...

Sorry to top-post (gMail mobile).
This looks like you missed a quote, colon, or something on a line
elsewhere in the file (likely above it). Find that and this should be
fixed.

Hi all,
I have a solitaire game in which I use a "Pile" class. This class is
meant to hold a bunch of cards, so I subclass it for the deck, the ace
stacks, and the seven main stacks, defining rules and methods for each
but also relying on the parent Pile class's methods and attributes.
However, I k
