Embrace whitespace

"Your code is easiest to read just after you've written it. Your future self will find your code far less readable days, weeks, or months after you've written it. When it comes to code readability, whitespace is your friend. Whitespace around operators Compare this: To this: I find that second one more readable because the operations we're performing are more obvious (as is the order of operations). Too much whitespace can hurt readability though: This seems like a step backward because we've lost those three groups we had before. With both typography and visual design, more whitespace isn't always better."

"Using line breaks for implicit line continuation Adding extra line breaks to code can improve readability. Putting line breaks within braces, brackets, or parentheses in Python creates an implicit line continuation. Python pretty much ignores line breaks within open braces, brackets, and parentheses, the same way it ignores most space characters within a line of code. If your code is wrapped in a bracket, brace, or parentheses, you can add as many line breaks as you'd like and Python will still treat the code as a single "line"."

Readable code is clearest immediately after writing but becomes harder for a developer to parse over time. Strategic whitespace around operators clarifies operations and order of operations. Excessive or misplaced whitespace can obscure logical groupings and reduce clarity. Auto-formatters such as ruff or black enforce certain whitespace choices and limit control over formatting, although some whitespace decisions remain manual. Line breaks inside braces, brackets, and parentheses create implicit continuation and permit readable multi-line layouts without changing semantics. Breaking comprehensions at logical boundaries—mapping, looping, and conditional parts—improves comprehension.
