Pylint is a static code analysis tool for the Python programming language. It is named following a common convention in Python of a "py" prefix, and a nod to the C programming lint program. It follows the style recommended by PEP 8, the Python style guide.{{cite web |url=https://www.python.org/dev/peps/pep-0008/ |title=PEP 8 – Style Guide for Python Code |website=Python.org |date= |accessdate=2016-11-16}} It is similar to Pychecker and Pyflakes, but includes the following features:

• Checking the length of each line
• Checking that variable names are well-formed according to the project's coding standard
• Checking that declared interfaces are truly implemented.{{cite web |url=http://www.logilab.org/project/pylint |title=pylint (analyzes Python source code looking for bugs and signs of poor quality) |website=Logilab.org |date=2006-09-26 |accessdate=2016-11-16}}

It is also equipped with the Pyreverse module that allows UML diagrams to be generated from Python code.

It can be used as a stand-alone program, but also integrates with IDEs such as Eclipse with PyDev,{{cite web |url=http://www.pydev.org/manual_adv_pylint.html |title=PyLint |website=Pydev.org |date=2016-10-31 |accessdate=2016-11-16}} Spyder and Visual Studio Code,{{cite web |url=https://marketplace.visualstudio.com/items?itemName=tht13.python |title=Python for VSCode – Visual Studio Marketplace |website=Marketplace.visualstudio.com |date= |accessdate=2016-11-16}} and editors such as Atom,{{cite web|url=https://atom.io/packages/linter-pylint|title=linter-pylint|accessdate=2016-11-17}} GNU Emacs and Vim.
