=========================================

**Message emitted:**

``Consider using a dictionary comprehension``

**Description:**

*Emitted when we detect the creation of a dictionary using the dict() callable and a transient list. Although there is nothing syntactically wrong with this code, it is hard to read and can be simplified to a dict comprehension. Also it is faster since you don't need to create another transient list*

**Problematic code:**

.. literalinclude:: /data/messages/c/consider-using-dict-comprehension/bad.py
   :language: python

**Correct code:**

.. literalinclude:: /data/messages/c/consider-using-dict-comprehension/good.py
   :language: python
