class Patch

This class represents a patch in the environment. It manages pheromones released in a patch. It allows adding, filtering, and retrieving pheromones within the patch.

Attributes:

• __pheromones (List[Pheromone]): List of pheromones released in the patch.

Methods:

• count_items(self) -> int

• add_pheromone(self, pheromone:Pheromone)

• filter_pheromones(self) -> None

• get_pheromones(self) -> List[Pheromone]

Example:

>>> from models.patch import Patch
>>>
>>> patch = Patch()
>>>
>>> pheromone1 = Pheromone()
>>>
>>> patch.add_pheromone(pheromone1)
>>>
>>> patch.filter_pheromones()
>>>
>>> print(patch.get_pheromones())
