Python Programming Leftovers

  • Pylint: Making your Python code consistent

    Pylint is a higher-level Python style enforcer. While flake8 and black will take care of "local" style: where the newlines occur, how comments are formatted, or find issues like commented out code or bad practices in log formatting. Pylint is extremely aggressive by default. It will offer strong opinions on everything from checking if declared interfaces are actually implemented to opportunities to refactor duplicate code, which can be a lot to a new user. One way of introducing it gently to a project, or a team, is to start by turning all checkers off, and then enabling checkers one by one. This is especially useful if you already use flake8, black, and mypy: Pylint has quite a few checkers that overlap in functionality.
