pylint 2.0.0

python code static checker

Pylint is a Python source code analyzer which looks for programming errors, helps enforcing a coding standard and sniffs for some code smells (as defined in Martin Fowler’s Refactoring book).

Pylint has many rules enabled by default, way too much to silence them all on a minimally sized program. It’s highly configurable and handle pragmas to control it from within your code. Additionally, it is possible to write plugins to add your own checks.

It’s a free software distributed under the GNU General Public Licence.

Development is hosted on GitHub: https://github.com/PyCQA/pylint/

Install

Pylint requires astroid package (the later the better).

• https://github.com/PyCQA/astroid

Installation should be as simple as

python -m pip install astroid

Pylint requires isort package (the later the better).

• https://github.com/timothycrosley/isort

Installation should be as simple as

python -m pip install isort

If you want to install from a source distribution, extract the tarball and run the following commands

python setup.py install

You’ll have to install dependencies in a similar way. For debian and rpm packages, use your usual tools according to your Linux distribution.

More information about installation and available distribution format may be found in the user manual in the doc subdirectory.
