Hello, Peter.
I checked my sys.stdout.encoding and it prints:
>>> import sys
>>> sys.stdout.encoding
'cp1252'
Sometimes IDLE tells me I'm using characters that might not work
if I don't place this at the beginning of my script:
# -*- coding: cp1252 -*-
Other than that, I have not made any change

Just in case you didn't come across it, there's a howto that covers the
basics:
Hi all,
I have a card class. A card object simply consists of a pair of
numbers; 0,0 might be the ace of clubs, for example. I have a toString
method in my card class. Is there a way to just say str(card) instead
of card.toString()? Maybe some sort of basic, built-in function to
override? TIA. Oh,

You could write __str__ function
>>> class card(object):
... def __init__(self, card1, card2):
... self.card1, self.card2 = card1, card2
... def __str__(self):
... return str(str(self.card1)+','+str(self.card2))
...
>>> a = card(0,0)
>>> str(a)
'0,0'

It worked, thanks. Is there a list of these functions somewhere? That
is, the functions that map implicitly to operators or implied uses?
For example, printing will call __str__, as will a cal to str(). What
about math or comparison operators? I have heard of __eq__, __gt__,
and so on, but I tried

These are special method names.
View section 3.4 and below here

Thanks, and I also see what I did wrong with my __eq__ function.

Hi,
I'm trying to understand the syntax for reflection in python. I was wondering
about this.
From the example on diveintopython:
http://diveintopython.org/power_of_introspection/index.html
import statsout
def output(data, format="text"):
output_function = getattr(statsout, "output_%s"
I'm trying this example from python docs:
from time import gmtime, strftime
strftime("%a, %d %b %Y %H:%M:%S +", gmtime())
Output = 'Wed, 04 Aug 2010 17:58:42 +'
Is not there a string formatting option for the day without a leading
zero? Like: 'Wed, 4 Aug 2010 17:58:42 +'
It looks like
There are a few solutions here:

Hey Huy,
thanks. But what is the first parameter in this case? (Note there is nothing
here I'm trying to accomplish except understand).
In the original example, 'statsout' is the name of the module. In this case
there is no module so why can you substitute 'output_text'?
thanks,
Pete

*You can do like below Pete. Where globals has a reference to all
functions in this space.*
def output(data, format="text"):
output_function = getattr(globals()['FUNCTION'], "output_%s" %
format, statsout.output_text)
return output_function(data)

Oh, that's right, I should have tried to example in the interpreter instead
of in my head:P
Say Bob,
Is that the preferred method over something like:

Hi all,
Further to my questions about overriding builtin methods earlier, how
would I make a class able to be accessed and changed using index
notation? For example, take the following:
deck=CardPile(52) #creates a new deck of cards
print(len(deck)) #prints 52, thanks to my __len__ function
for c i

I have a side question,
I am using python 2.7.
Why do you use class A: instead of class A(object): ?

That depends how you create the Pile of 52 cards: list(52) also doesn't
generate 52 (random) items.
If you override __init__ to accept an integer that generates the cards for
you, this should work.

Suppose i have this string:
z = 'AT/CG'
How do i get this list:
zlist = ['A','T/C','G']
