The only way to do what you want is to use some mutable object to 'hold' your data in the enclosing namespace, and modify that object. You can use a list like you did, or some simple "class namespace: pass" with "ns = namespace()" and "ns.jobs = 1" or whatever you prefer. But otherwise, you just can't do that. Gotta deal. --S
