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:
manual documents, as described in
section 5, ``Document Classes.''
