Rods¶

Rods is a collection of Rod‘s, one representing the start, end and intermediary rods for the tower.

class towers.core.rods.Rods[source]¶

A collection of 3 Rod’s that form the Tower.

Parameters:	start (Rod) – The rod containing the disks at their start position. end (Rod) – The rod containing the disks at their end position. tmp (Rod) – The intermediary rod. height (int) – The height of the tower.
Raises:	InvalidTowerHeight – The height of the tower is invalid. InvalidRod – A rod is not of expected type Rod. InvalidRodHeight – A rod height is inconsistent with the specified height. DuplicateDisk – A rod contains a duplicate disk CorruptRod – A disk is on top of a disk of smaller size on a Rod.

__bool__()[source]¶

A Rods is considered True if it contains any disks on any rods.

Return type:	bool

__copy__()[source]¶

Return a shallow copy of this instance.

Return type:	Rods

__deepcopy__(*a)[source]¶

Return a deep copy of this instance.

Return type:	Rods

__iter__()[source]¶

Iterate over all the rods.

Return type:	Rod

__len__()[source]¶

Obtain the number of Rods.

Return type:	int

__nonzero__()[source]¶

A Rods is considered non-zero if it contains any disks on any rods.

Return type:	bool

classmethod from_json(d)[source]¶

Return a class instance from a json serializable representation.

Parameters:	d (str\|dict) – The json or decoded-json from which to create a new instance.
Return type:	`Rods`
Raises:	See `Rods`.__new__.

height¶

Retrieve the height of the rods (ie: max number of disks each one can hold).

Return type:	int

to_json()[source]¶

Return a json serializable representation of this instance.

Return type:	object

validate()[source]¶

Perform self validation.

Raises:	DuplicateDisk – This rod already contains this disk CorruptRod – A disk is on top of a disk of smaller size.
