If you're working with others, though, then it becomes very important. They're not very important if you're the only developer on your team. And make sure that the rules are completely oblivious to the function's arity. And make sure neither of the rules causes me to have to re-indent things just because a function picked up an additional argument. Give me one rule for when it all fits on one line, and another rule for when it doesn't. Personally, I don't want formatting rules where you might decide to format the arguments to a function in different ways depending on the specifics of what other arguments the function has. Which is where I was going with the comment about edge cases. You've also got to contend with the first not being a comprehension meaning that the comprehension's indenting can't so easily be kept the same: (Which admittedly looks reasonably tidy, but starts to get gross again if we start looking at 3-ary functions.) That works if they're both comprehensions, but starts looking more gross when the 2nd argument isn't a comprehension, and now you're looking at deciding among options like Having a bunch of special cases just to match what someone might think is more aesthetically pleasing in specific situations is not a desirable feature in a set of autoformatting rules. IMO, that's good, even if it isn't what we're all used to. Versus, with Black's style, the answer is easy and straightforward, because you just do it the same way you would anywhere else: You'll have a train wreck of bad options about where to put the braces and how to place the comprehension's body in relation to the braces that enclose it. For example, we can't follow the first option and get clean formatting with a function like zip. But I can't see a way to preserve the tradition without creating special or edge cases. In this particular case, that may result in code that breaks with tradition. The argument to that function includes the braces, so the opening one needs to go on a new line, and the closing one needs to be indented as well. And all the arguments need to be indented to the same level. It looks to me like a result of a couple rules that, in general, are sound: First, if an argument list can't fit all on one line, then every argument needs to go on a new line. Let's first set the default formatter to use Black you can do that by typing this into the settings.That one actually makes a lot of sense to me, even if I've got to admit that I tend to go with the first option in my own code. The settings file is in json format, so you need to enclose everything in a curly bracket ( ). Inside newly created folder, create a json file and name it settings.json.Ĭonfigure Black Formatter in Settings File (If you want to disable these extensions, you can disable the extension per workspace in Visual Studio Code.)Ĭreate a new folder in the project root folder, and name it. (You might want to install "isort" as well - also from Microsoft - if you want your import statements to sort when you save file.) Do the same with "Flake8", also from Microsoft. Type "Black Formatter" to download extension from Microsoft. On Visual Studio Code, go to View > Extensions to see list of extensions. They are now migrating to individual Python tool extension. But it seems the built-in support is going to be deprecated soon. We will use Black as a Python code formatter, and Flake8 as a Python linter.īlack and Flake8 can be installed using pip, and configured that way. These two tools are optional, but can be an essential part of maintaining code quality and consistency in software development projects, especially in large or collaborative teams where adherence to a common coding style is crucial. In this tutorial, I will demonstrate how you might configure VSCode to use code formatter and linter for Python 3.Ī code formatter is a tool or software that automatically and consistently formats source code in a programming language according to a predefined set of style rules or coding conventions.Ī code linter (or simply "linter") is a tool that analyzes source code for potential errors, coding style violations, and other issues.
