Well, whether the reason is obvious, I do not know, but the way and

When I was at Data General, writing C (and a little C++), we had a set
of internal coding conventions that mandated a single return point for
a function. Goto's were used during error checks to branch to the
function exit; something like this:

Hi there,
Exploring the Python standard library, I was surprised to see that several
packages (ConfigParser, logging...) use mixed case for methods all over the
place. I assume that they were written back when the Python styling
guidelines were not well-defined.

Hi everyone:
I'm using "translation" in the sense of string.maketrans here.
I am trying to efficiently compare if two string translations
"conflict" -- that is, either they differently translate the same
letter, or they translate two different letters to the same one. Here
are some examples:

Any reason it should? I don't know GMP (only that it exists), but adding

Hi Diez,
Thanks for this, I had seen zip() before but had no idea
really what it does, this will serve as good motivation to
find out more.
I'm amazed at what this language can do (and the helpfulness
of the people on the list here).
Best,

Hi,
I seem to be having a problem with a list being share across multiple
instantiations of it and dont quite understand why this is happening.
My class looks like this,
class Widget(object):
_parent = None
_children = []
def __init__(self, parent=None):
self.parent = parent
Thanks Luis, more code for me to study and learn from.

Ah thank you for clarifying, I did confuse instance and class
attributes from creating the list in the class def. I actually just
spiffed up that class to represent a portion of a much larger class
that needs getter and setter for children. Doing as you said fixed my
problem, heres the code as refe
