My advice is to just TRY python and resolve the "slow" speed if you ever

hat this has similarities to call with continuation,
and that you can use statesaver.c & generators to achieve something
vaguely similar to continuations, but I'm more after this specific
approach, rather than that general approach. (After all, even ruby
notes that their most common use for call/cc is to obfuscate code -
often accidentally - and I'm not particularly interested in that :)
Whereas the unix style exec is well understood by many people, and
when it's appropriate can be extremely useful. My suspicion is that
my ideasabove actually maps to a common idiom, but I'm curious to
find that commonidiom.
I'm fairly certain something like this could be implemented using
greenlets, and also fairly certain that Stackless has been down this
route in the past, but I'm not able to find something like this exec
style call there. (Which is after all more constrained than your usual
call with continuation approach)
So, sorry for the length of this, but if anyone has any thoughts, I'd be
very interested. If they don't, I hope it was interesting :)

And after:

We'd then execute line 6, and after executing that line, our stack would
look like this:
[ { "context" : "greet", pc : 6 }, { "context" : "__main__", pc : 12 }, ]
We're falling off the end of a function at that point, so we'd pop the top

If you're looking to do this in a production environment I'm personally an
advocate of learning what's going on in the core and then using an existing
library.
(The reason Kamaelia exists is because I wondered if there was an
alternative, potentially clearer way of writing these things, most
people would quite sensibly just use Twisted - especially given you
can buy a book on it! I personally think Kamaelia is cleaner, but then
I would think that :)

Yes, I konw what you mean. And thats the right way to do it - for
beginners. --But not for someone who allready know programmings things
for many years.
They ask themself: How can I do this in Python? I can remember, it was
that-way with Perl or C or C++ or whatever.
So, not only a ververter c
Hmm.. thanks. I did this changes, but without any performance profits.

Yes. But it still runns very slowly.
If someone is really interested in speed optimization, I can publish my
PI-calc code.
Maybe for some Python compiler/interpreter hackers... ;-)
(There are only 2 while-loops, one within another, and some simple basic
calculations. Nothing special.)

Hi,
I'm a pretty sound programmer in C++, but would like to learn python! Does
anyone know of any tutorial s aimed at me?? My biggest confusion so far is
the lack of pointers in Python ..

Hi,
I'm trying to write a script to parse a .cpp file and begin to create a
'translational unit'.
To do this i need to:
Go through the file and remove all 'C' comments as

(can be on multiple lines)
Go through and remove all 'C++' comments, anything between // and '\n' char.

Hi,
I've got a string s, and i want to shift all the letters up by one, eg a->b,
b->c z->a
In c++ i can do this quite simply with
if(C == 'z') C='a';
else C++;
but i can't work out how to do this this in python??

Hi,
I'm fairly new at Python, and have the following code that works but isn't
very concise, is there a better way of writing it?? It seems much more
lengthy than python code i have read. :-)

Do expicit pointers exist in python??
if i do:
a = [5,7]
b = a
a.empty()
b = ?
how do i do explicit pointers??

"Function objects also support getting and setting arbitrary
attributes, which can be used, for example, to attach metadata to
functions. Regular attribute dot-notation is used to get and set such
attributes. Note that the current implementation only supports
function attributes on user-

Pickling is an obvious issue, but it seems like there is nothing wrong
with the copy semantics and that the limitations are artificial and
