In this lesson you’ll get an introduction into the Python linter PyLint. Throughout the course you’ll work with this linter.

PyLint Code Linter Overview
00:00 Today I want to show you how to install Pylint. Pylint is a really well-known linter for Python, like I said earlier. Pylint has a number of very useful features. Number one, it can check your Python code for compliance with the PEP 8 style guide, which is a very common style guide that’s often used on Python projects, so I would highly recommend that you learn more about it. And Pylint can help you make sure that the Python code it runs on actually follows the PEP 8 style guide.
00:31 Pylint can also find and tell you about certain classes of errors that might be in your code. Things like unused variables, stuff that I mentioned before.
00:41 And it has some more, like, really interesting features. For example, it can also generate UML diagrams and it is very customizable in general. I think that’s one of the potential downsides of Pylint—that there’s a huge number of settings you can play with, so it might take you a while to find the optimum setting.
00:59 But once you’ve got it set up well—or you’re just running with the default configuration, which is also a viable option—then it’s a really great tool that provides you with a lot of helpful feedback and will help you write better code and cleaner Python code.
