[Zope] Using Python Script as module?

[ender]

Simplified example:

#
def fa():
    print 'fa executed'

def fb():
    fa()

fb()
return printed
#

This does not work, as the PS itself is apparently not a module
level namespace. I can call fa() directly, although. Is there some way
to call a function defined in the PS inside another function? Is there
something like the PS namespace?

I haven't played with python scripts too much but with python methods you 
would have to declare your functions as global

so 

def fa(): pass

def fb(): 
    global fa
    fa()
