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

Question

What does the @ symbol do in Python?

Answer 1

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

• PEP 318: Decorators

• Python Decorators - Python Wiki

• The most common Python decorators are:

  • @property
  • @classmethod
  • @staticmethod

An @ in the middle of a line is probably matrix multiplication:

• @ as a binary operator.
