How to return a simple variable from a function (still newbie) ?

[Paul Hummer]

How about restructuring your function like this:

def some_function( z,y ):
  z = 2
  y[2] = 'global ?'
  return z

And then you'll have to react to the returning variable, like this in
your code:

x = 5
y = [1,2,3,4]
print x,y
print some_function( x, y )
print x,y

Now, it appears like you want some_function() to change x and y.  It
doesn't really work that way.  You'd have to either pass the variables
by reference into the function, or overwrite the existing values with
whatever the function returns.  That might be beyond your scope now though.

Keep plugging, and welcome to Python!
