DTNotation

Classes for working with DT notation representing planar projections of curves.

API documentation

class pyknotid.representations.dtnotation.DTNotation(code)

Bases: object

Class for containing and manipulation DT notation.

Parameters:code (str or array-like) – The DT code. Must be either a string of entries separated by spaces, or an array.

gauss_code_string()

Returns a string containing a Gauss code, in the format accepted by GaussCode.

To get a GaussCode object, you can pass this string when initialising it, or use DTNotation.representation().

representation(**kwargs)

Returns a Representation representing the same DT code. The crossing orientations (and therefore resulting chirality) are chosen arbitrarily.
