4.2 Hierarchical Structure

LaTeX expects documents to be arranged in a conventional, hierarchical way, with chapters, sections, sub-sections, appendixes, and the like. These are marked using macros rather than environments, probably because the end of a section can be safely inferred when a section of equal or higher level starts.

There are six ``levels'' of sectioning in the document classes used for Python documentation, and the deepest two levels1 are not used. The levels are:

Level | Macro Name | Notes
--- | --- | ---
1 | `\chapter` | (1)
2 | `\section` |
3 | `\subsection` |
4 | `\subsubsection` |
5 | `\paragraph` | (2)
6 | `\subparagraph` |

Notes:

(1)
  Only used for the `manual` documents, as described in section 5, ``Document Classes.''
(2)
  Not the same as a paragraph of text; nobody seems to use this.

  The deepest levels have the highest numbers in the table.
