Pylint is a source-code, bug and quality checker 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] and Visual Studio Code,[7] and editors such as Atom,[8] GNU Emacs and Vim.

It has received favourable reviews.[9][10][11]
