============================
B101: Test for use of assert
============================
This plugin test checks for the use of the Python ``assert`` keyword. It was
discovered that some projects used assert to enforce interface constraints.
However, assert is removed with compiling to optimised byte code (python -o
producing \*.pyo files). This caused various protections to be removed. The use
of assert is also considered as general bad practice in OpenStack codebases.
Please see
https://docs.python.org/2/reference/simple_stmts.html#the-assert-statement for
more info on ``assert``
:Example:
.. code-block:: none
>> Issue: Use of assert detected. The enclosed code will be removed when
compiling to optimised byte code.
Severity: Low Confidence: High
Location: ./examples/assert.py:1
1 assert logged_in
2 display_assets()
