Hi,

Sorry, I have another problem here. Given this snipplet,

>>> def b(s):
... exec(s)
... exec('print "x= " + str(x)')
...
>>> b('x = 10')
x= 10
>>>
>>> print x
Traceback (most recent call last):
   File "<stdin>", line 1, in ?
NameError: name 'x' is not defined
>>>

Clearly, all the objects that were declared using exec() in function b
went out of scope, is there anyway to prevent this from happening?

What I really need is this, for example, in a class,

1. a function to initialize a set of objects
2. a function which carries commands to act on the object (unknown at
compile time)
3. a function to read the values of the set of objects

So, if the objects went out of scope after leaving (1), then I am rather
screwed when I'm in (2). Any remedies?

Thanks
Maurice
