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.^[4] 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.^[5]

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,^[6] Spyder and Visual Studio Code,^[7] and editors such as Atom,^[8] GNU Emacs and Vim.
