what does the @... do in Python?

Question

I'm very far in the python tutorial but I still don't get it what the @-thing is for?
could someone explain to me?

Answer 1

@ is a decorator. It is used to temporarily alter the behavior of a function/method - whether it's defined or called.
The best learning example is a function wrapper - by using @ before the method is called, it acts as an argument for the wrapper function.
