useless-import-alias / C0414
============================

**Message emitted:**

``Import alias does not rename original package``

**Description:**

*Used when an import alias is same as original package, e.g., using import numpy as numpy instead of import numpy as np.*

**Problematic code:**

.. literalinclude:: /data/messages/u/useless-import-alias/bad.py
   :language: python

**Correct code:**

.. literalinclude:: /data/messages/u/useless-import-alias/good.py
   :language: python


**Additional details:**

Known issue
-----------

If you prefer to use "from-as" to explicitly reexport in API (``from fruit import orange as orange``)
instead of using ``__all__`` this message will be a false positive.

Use ``--allow-reexport-from-package`` to allow explicit reexports by alias
in package ``__init__`` files.
