===================
As an OO exercise I have a factory pattern that returns class objects that
each have an "action" method. ClassObj.action() in turn returns a code
object in my recursive process loop.
I create the code objects as a one time step outside my factory pattern and
potential class definitions, then reference them in my potential classes
which seems to work as expected.
When I create the code objects though, it seems a couple different ways work
and I'm wondering which is better and why (or is there a more correct
technique in this situation)?
The two different ways are illustrated below:
Python 2.4.1 (#2, Mar 31 2005, 00:05:10)
[GCC 3.3 20030304 (Apple Computer, Inc. build 1666)]
Type "help", "copyright", "credits" or "license" for more information.
def foo(st): .... print st
.... exp1 = 'foo("#expersion 1#")'
exp2 = 'foo("#expersion 2#")'
obj1 = compile(exp1, 'whatever', 'single')
exec obj1 #expersion 1# obj2 = compile(exp2, 'whatever', 'exec')
exec obj2 #expersion 2#
Thank you,
