have to convert the month to an integer.

I understand that two leading underscores in a class attribute make the
attribute private. But I often see things that are coded up with one
underscore. Unless I'm missing something, there's a idiom going on here.
Why do people sometimes use one leading underscore?

=Why do people
This is all an intro learning experience for me, so please feel free to
explain why what I'm trying to do is not a good idea.
In the Cookbook, they have a recipe for how to create global constants.
-
class _const:
class ConstError(TypeError): pass
def
The short story is that someone left, but before he left he checked in a
.pyc and then both the directory was destroyed and the backups all got
shredded (don't ask*). Is there anything that can be extracted? I looked
on the web and the subject seems to get different answers, all old.
Any joy?
I have a table of integers and each time I look up a value from the table
I want to call a function using the table entry as an index into an array
whose values are the different functions. I haven't seen anything on how
to do this in python.

I'm new to python and I have a need to do this.
The Cookbook almost takes me there with:
def check_order(option, opt_str, value, parser):
if parser.values.b:
raise OptionValueError(can't use %s after -b % opt_str)
setattr(parser.values, option.dest, 1)
but warns that the it
I decided I could be more articulate. I hope this helps.
I'm writing a program that needs to process options. Due to the nature of
the program with its large number of commandline options, I would like to
write a callback to be set inside add_option.
Something like this:
parser.add_option(-b,

class ConstError(TypeError): pass
def __setattr__(self,name,value):
if self.__dict__.has_key(name):
