Closures python,scheme,ruby

[paolo veronelli]

I've a vague idea of the differences,I don't know scheme anyway.

I'd like to see an example to show what is missing in python about 
closures and
possibly understand if ruby is better in this sense.

Iuse ruby and python in parallel for my job just to learn them and their 
differences and python is shorter and cleaner ,but i feel it's missing 
something,
in closures.Any hints?
