Koodilohko

Koodilohko is Finnish for a block of source code. In programming and related fields, the term refers to a portion of code that is treated as a single unit for reading, execution, or display, such as when sharing examples in documentation, teaching materials, or source files.

The word combines koodi (code) and lohko (block), and it is used as the Finnish counterpart to the English term “code block.” It covers both the conceptual idea of a contiguous section of code and the practical formatting used to present that section in text or in an editor.

In documentation and learning resources, koodilohko is commonly displayed with preserved formatting and can be annotated with the programming language to enable syntax highlighting. In Markdown, code blocks are often created with triple backticks or by indentation; fenced code blocks may specify a language identifier to improve readability. HTML uses pre and code elements to render a koodilohko, while LaTeX can employ environments such as verbatim or listings for similar purposes.

In actual programming, a code block typically defines a scope or grouping of statements. Languages with braces, such as C or Java, use braces to delimit blocks; Python relies on indentation; Ruby uses end to close blocks; other languages use dedicated keywords. The exact rules vary by language, but the concept remains a contiguous, interpretable segment of code.

Best practices for using koodilohko include specifying the language for proper highlighting, keeping blocks focused and readable, and avoiding exposure of sensitive data. When possible, code blocks should be accompanied by explanations and minimal, reproducible examples.
