Since  version 2 thats true. Its whats called embedded scopes
Thus you can do this:

def foo():
   def bar():
       print "Hello from bar"
   bar()

Now calling foo will print the messsaage but if you try to 
call bar() from outside foo() your get a name error. 

In earlier versions of Python I think you could still type 
the code but bar would still be seen at the module level.

I would imagine newbies will be interested but you are more 
likely to find them on the python-tutor mailing list rather than 
edu-sig which is targetted at educators rather than students...

There's a hint there somewhere <wink>
