Can anyone explain to me why
struct.pack('HB',1,2) gives 3 bytes, whereas struct.pack('BH',1,2)
gives 4 bytes?

1 is a literal, you can't assign it to something. Are you trying to
use it as a variable name?

Yeah, I figured it out 2 minutes after I posted, d'oh!
class Anvil(object):
def __cmp__(self. other):
return 1

If I have a list of items of mixed type, can I put something into it
such that after a list.sort(), is guaranteed to be at the end of the
list?
Looking at http://www.python.org/doc/2.3.5/ref/comparisons.html
"Most other types compare unequal unless they are the same object; the

Hi all-
I'm looking for a data structure that is a bit like a dictionary or a
hash map. In particular, I want a mapping of floats to objects.
However, I want to map a RANGE of floats to an object.
This will be used for timestamped storage / lookup, where the float
represents the timestamp.
get(x)
print sum([ord(ch)-96 for ch in small])

Why not make chromosome itself a class?
class BasicChromosome(object):
def __init__(self, data):
self.data = data
def crossover(self):
[stuff here]
You can subclass this as needed, altering the crossover method as necessary.
...perhaps I didn't understand your question.

Small, off-topic nitpick:
please don't use "l" (lower-case el) as a variable name.

Hi all-
I was reading http://dirtsimple.org/2004/12/python-is-not-java.html, in
particular the part about "getters and setters are evil":
"In Java, you have to use getters and setters because using public fields
gives you no opportunity to go back and change your mind later to using
getters and set
