day19.day19 module

Day19 solution.

day19.day19.get_input(path: str) → tuple[list[Workflow], list[Part]]

Open file and parse.

Returns well formed workflows and parts classes.

Parameters:

path (str) – filepath for data

Returns:

list of workflows and parts.

Return type:

tuple[list[Workflow], list[Part]]

day19.day19.main() → None

Load input file and run part1/part2.

day19.day19.part1(workflows: list[Workflow], parts: list[Part]) → int

Solve part1.

day19.day19.part2(workflows: list[Workflow]) → int

Solve part2.

Processes a part.

Returns the part rating (or 0 if rejected)

Parameters:

• workflows (dict[str, Workflow]) – list of workflows.

• part (Part) – part to process

Returns:

value of part (or 0 if rejected)

Return type:

int

day19.day19.solve_part2(workflows: dict[str, Workflow]) → int

Solve part2.
