Possible, but not needed. I would recommend looking at either TinyPy
or LunaticPython to do safe embedded Python or Lua respectively.
Unless you expect users to running arbitrary downloaded code in your
game, you can just use python+exec though.

Python _is_ the scripting language to use in your game.

This is getting off topic for a game oriented mailing list, but
many of the things other languages use macro to accomplish come
naturally to Python because it is dynamically typed. For
instance the function:
def do_add(x, y):
return x + y
will work with integers, floats, complex numbers, lists and any
other class that defines an addition operation. Python has many
hooks that take callback functions. These can redefine the way
imports work, for instance. Also, metaclasses allow one to
change how class declarations work. So though there is no
mechanism to add new syntax and constructs to the Python
language, there are plenty of ways to change how the existing
syntax works.

While we're on this kind of topic what is the best approach in
python to creating code macros? That is ability to write a
higher level language (or script) which translates down into
python? Decorators look like they would be part of that story.
Is that the best way or is their a more general way?
Thanks,
Lin
p.s. I used to write code macros in LISP... context I am
coming from.

Yanom -
A decorator is a method that takes another method as a
parameter so that it can do something. It is usually used
for aspect oriented programming.
For example:
def logThisMethodCall(methodCall)
# Do some logging here
@logThisMethodCall
def myMethod(a,b,c)
# do Somthing in here
Now, whenever you call "myMethod", logThisMethodCall gets
called first, with the invocation of myMethod passed into
it. You can use it for logging, security (i.e. does this
person have permission to be calling this), etc.

This isn't quite right. logThisMethodCall doesn't get called
when you call myMethod, but when you _define_ myMethod. So
to fix this example:
def logThisMethodCall(methodCall):
def result(a,b,c):
# do some logging here
methodCall(a,b,c)
return result
@logThisMethodCall
def myMethod(a,b,c):
# do something here
When you define myMethod, logThisMethodCall is called to
create a replacement function for myMethod. it returns a new
function "result" which gets called instead of the original
myMethod whenever someone calls myMethod. result does some
logging and then calls the orginal myMethod.
