A Jupyter Notebook document is a JSON file, following a versioned schema, usually ending with the ".ipynb" extension. The main parts of the Jupyter Notebooks are: Metadata, Notebook format and list of cells. Metadata is a data Dictionary of definitions to set up and display the notebook. Notebook Format is a version number of the software.
A notebook interface or computational notebook is a virtual notebook environment used for literate programming, a method of writing computer programs. [1] Some notebooks are WYSIWYG environments including executable calculations embedded in formatted documents; others separate calculations and text into separate sections.
The off-side rule describes syntax of a computer programming language that defines the bounds of a code block via indentation. [1] [2]The term was coined by Peter Landin, possibly as a pun on the offside law in association football.
Boo uses indentation, a similar syntax, and a similar object model. [235] Cobra uses indentation and a similar syntax, and its Acknowledgements document lists Python first among languages that influenced it. [236] CoffeeScript, a programming language that cross-compiles to JavaScript, has Python-inspired syntax.
Python borrows this feature from its predecessor ABC: instead of punctuation or keywords, it uses indentation to indicate the run of a block. In so-called "free-format" languages—that use the block structure derived from ALGOL —blocks of code are set off with braces ( { } ) or keywords.
IPython continued to exist as a Python shell and kernel for Jupyter, but the notebook interface and other language-agnostic parts of IPython were moved under the Jupyter name. [11] [12] Jupyter is language agnostic and its name is a reference to core programming languages supported by Jupyter, which are Julia, Python, and R. [13]

In computer programming, indentation style is a convention, a.k.a. style, governing the indentation of blocks of source code.An indentation style generally involves consistent width of whitespace (indentation size) before each line of a block, so that the lines of code appear to be related, and dictates whether to use space or tab characters for the indentation whitespace.
