[Zope] call by reference

[Arenz, Ralph]

Hi,

for some external methods in zope i have do
write some python scripts.

Here my question:
I want do a 'function - call by reference' in python.

My function definition is like that:

 def foo(foo1,foo2):
       foo1=1
       foo2=2	

My intention is to call the function from an other function
in the python script like

 def foo2():
      x,y=2,3
      foo(x,y)		

I know that python is working with seperate namespaces
in case of function calls, but is there a work-around for
this problem.
