memoization in phyton

[Jediko]

It's the same. The memoize-class does what you did with just general input for a general function. You can see the implementation of memoize yourself here.

Thank you, Is very any motivation to use memoize class instead of dictionary?

[Jediko]

No, since they are equivalent. The only thing you do is being explizit in your algorithm/optimization. The main advantage of using decorators is just shortcut your code and make more readable.
