Debugging hasn't been an issue so much. This approach generates two lists, one of elements greater than or equal to the "pivot" element (in this case the first element of the list), and one of elements less than the pivot. markdown and Java). Writing source code has the great advantage of being simple. Literate programming involves having a meta language that is extended into the target source code through nested macros. The main focus is on using Python to do interesting mathematical calculations, with an emphasis on learning by example. README.md is the modern day heir to literate programming is a bit different than it is possible to partially emulate literate programming by symlinking README.md to a source code file (i.e. Doctest makes innovative [citation needed] use of the following Python capabilities:.

Literate programming is a programming paradigm introduced by Donald Knuth in which a computer program is given an explanation of its logic in a natural language, such as English, interspersed with snippets of macros and traditional source code, from which compilable source code can be generated.
