I would like to do:
def foo(self,x,y=self.a)
where the default value for y=self.a. Since this is not possible, I
wind up doing
def foo(self,x,y=None)
if not y:
y=self.a
but that seems kind of clumsy.
Is there a better way to do this?
Thanks in advance

I'm not sure this is possible, but I would like to have
a list of objects
A=[a,b,c,d,...,z]
where, in the midst of a lot of processing I might do something like,
A[0].do_something_which_changes_the_properties()
which alter the properties of the object 'a'.
The trick is that I would like A to

Hi,
I have lists of the following type:
[1,2,3,[5,6]]
and I want to produce the following strings from this as
'0-1-2-3-5'
'0-1-2-3-6'
That was easy enough. The problem is that these can be nested. For
example:
[1,2,3,[5,6],[7,8,9]]
which should produce
'0-1-2-3-5-7'
'0-1-2-3-5-8'
'0-1-2-3-

I have multiple packages that have many of the same function names. Is
it possible to do
from package1 import *
from package2 import *
without overwriting similarly named objects from package1 with
material in package2? How about a way to do this that at least gives a
warning?
Thanks.

I am writing an algorithm that takes objects (i.e. graphs with
thousands of nodes) into a "hypothetical" state. I need to keep a
history of these hypothetical objects depending on what happens to
them later. Note that these hypothetical objects are intimately
operated on, changed, and made otherwi

hi,
I have the following problem: I have two objects, say, A and B, which
are both legitimate stand-alone objects with lives of their own.
A contains B as a property, so I often do
A.B.foo()
the problem is that some functions inside of B actually need A
(remember I said they were both standalon
I have a large class that is a child of list. I need to pickle it, but
it's not working. For example, I have reduced it to the following:
class Mylist(list):
def __init__(self,x=[]):
list.__init__(self,x)
and I cannot even get this to pickle right.

Suppose I have two different command windows going on the same
machine, each running their own Python interpreters.
Is it possible to access the variables in one of the interpreter-
sessions from the other?
It turns out I have limited control over one of the sessions (i.e.

would it be possible to use one of an object's methods without
initializing the object?
In other words, if I have:
class Test:
def __init__(self):
print 'init'
def foo(self):
print 'foo'
and I want to use the foo function without hitting the
initialize constructor function.
Is t
Hi,
I am studying some examples in a tutorial where there are a lot of
leading >>> characters and ellipsis in the text. This makes it hard to
cut and paste into the IPython interpreter since it doesn't like these
strings.
Is there another interpreter I could use that will appropriately

I am getting started with your logging module and I went through the
tutorial and know-how to create a top-level 'root' logger with the
appropriate handlers.
I have a number of functions,say,
def foo1()
def foo2()
...
foo1() # foo2 calls foo1
and I know how to connect each of these f
