Hi;

For efficiency reasons many CPUs require particular primitive data
types (integers/pointers of various sizes) to be placed in memory at
particular boundaries. For example, shorts (H above, usually two bytes

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

Hello ,
following scenario
list_current = [ welcome, search, done, result]
list_ldap = [ welcome, hello]
result:
list_toadd = [ hello]
by words said , i want to check if list item from list_ldap exists in
list_current if not i want to add it to list_toadd.
Thanks!

1 is a literal, you can't assign it to something. Are you trying to

I believe the best way to implement this would be a binary search
(bisect?) on the actual times, which would be O(log N). Though since
they are timestamps they should be monotonically increasing, in which
case at least you don't have to go to the expense of sorting them.

If I have a list of items of mixed type, can I put something into it

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

You can pass a cmp-function that will always make one object being greater
than all others.

bisect is definitely the way to go. You should take care with
floating point precision, though. One way to do this is to choose a
number of digits of precision that you want, and then internally to
your class, multiply the keys by 10**precision and truncate, so that
you are working
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.

You can subclass this as needed, altering the crossover method as necessary.
