Pylint Tutorial – How to Write Clean Python

In this Pylint tutorial video you'll see how to install and set up the Pylint code linter for Python step by step. We'll go over why you should use a code linter like Pylint, Flake8, Pyflakes, or other static analysis tools—and how they can help you write cleaner and more Pythonic code.

Pylint is a well-known static analysis tool for Python 2 and 3. It has a number of useful features, like checking your code for compliance with the PEP 8 Python style guide. It makes sure that your code follows the code style guide and it can also automatically identify common bugs and errors in your Python code.

To set up Pylint you'll first need to install it with the `pip install` command and then you can run it on any Python file with the "pylint" command. Pylint inspects your code and then gives you feedback on it. Besides running Pylint from the command-line you can also integrate it into your editor to get live feedback on your Python code.

In this Pylint tutorial I'm going over the feedback produced by Pylint and I'm taking it to refactor and improve the quality of my code. You can get this setup up and running in a few minutes and it'll quickly help you write better and cleaner Python code.

My new favorite python youtuber! Really love how you're bridging the gap between beginner and intermediate. Not many other people do that very well but you're nailing it.

The score is based on the number of errors and the number of lines. 10 is "perfect" and there is no lower bound to the score.

If you use Visual Studio Code, Pylint is included by default. You just have to give installation permission. Style errors are then highlighted automagically.

3:26 Could anyone tell me in which context he recommends using vEnv? To install any (surf?) Python tool/dependency?

Wondering how you edited your terminal window removing the title bar??? Great video! Keep it up with the great content!

You should do videos about job interview in python too...for example: What a python developer must know before a job interview?

[petrockspiracy]

Can anyone explain to me why I get a mixed-indentation error for using tabs only when I haven't used spaces? If I just use spaces it's okay but surely no one actually types out four spaces... I don't get it.

Edit: okay I just did adjusted the option at the bottom right of the window to be spaces and it converts them for you

[kennyPAGC]

pylint missed the triple whitespace between the keyword def and the function name crash

[ckortreat]

how did you make your terminal frameless??

[Danny-uqzf]

What shell is that!? Please make a video on installing and customizing that terminal/shell!

[dmytroohorodnik]

You can run "pylint pylint" :)
