inner function accessing outer function's variable

    • the variable of the outer function is available only when that function is running on, ie it vanishes when my_outer_function ends.

    That's not entirely true. The variable is available in my_outer_function 's scope. my_inner_function has the scope of its own declarations and its parent's scope.

    my_inner_function references a variable outside of its own scope, and so those references are bound to my_inner_function as a closure when its parent's scope is no longer available. To learn more about closures, see Can you explain closures (as they relate to Python)? (taken from Paul Rooney's comment)
