Usage of '@@' syntax in python

Question

I ran into the double @@ symbol in the following code: https://github.com/tensorflow/tensorflow/blob/master/tensorflow/python/ops/rnn_cell.py

I understand that the @ is used as a decorator. But I can't seem to find any information on the use of @@?

Answer 1

The @@ is used only in docstrings not in code. It is no valid Python syntax.

An external tool uses this for generating links to other classes in the documentation.
