What does the “at” (@) symbol do in Python?

Question

I\'m looking at some Python code which used the @ symbol, but I have no idea what it does. I also do not know what to search for as searching Python docs or Goo

Answer 1

To say what others have in a different way: yes, it is a decorator.

In Python, it's like:

1. Creating a function (follows under the @ call)
2. Calling another function to operate on your created function. This returns a new function. The function that you call is the argument of the @.
3. Replacing the function defined with the new function returned.

This can be used for all kinds of useful things, made possible because functions are objects and just necessary just instructions.
