The way you want to work with closures the Python way is not to do it
but use a class to hold the state. That's sometimes sad but true.

There's a workaround (but see it only as one; it's not pretty).
def outer ():
var = 
def inner ():
var += 1
Now if you call outer it's returns a function which when called changes
the value of var.
