comparison-of-constants / R0133
===============================

**Message emitted:**

``Comparison between constants: '%s %s %s' has a constant value``

**Description:**

*When two literals are compared with each other the result is a constant. Using the constant directly is both easier to read and more performant. Initializing 'True' and 'False' this way is not required since Python 2.3.*

**Problematic code:**

.. literalinclude:: /data/messages/c/comparison-of-constants/bad.py
   :language: python

**Correct code:**

.. literalinclude:: /data/messages/c/comparison-of-constants/good.py
   :language: python
