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

An @ symbol at the beginning of a line is used for class, function and method decorators.

Python Decorators

The most common Python decorators you'll run into are:

@property

@classmethod

@staticmethod

If you see an @ in the middle of a line, that's a different thing, matrix multiplication. Scroll down to see other answers that address that use of @.
