In the programming world, indentation has been essential for structuring code. Unlike most languages, which use braces and keywords to mark code blocks, Python uses whitespaces and indents only to distinguish code blocks as they return.
Such a feature is crucial to how Python programs are written, read, and executed, as well as the heart of the role of the language in the world of programming.
