Solution¶
With this maze structure:
house = {
"living": {
"exits": {"north": "kitchen", "outside": "garden", "upstairs": "bedroom"},
"people": ["James"],
"capacity": 2,
},
"kitchen": {"exits": {"south": "living"}, "people": [], "capacity": 1},
"garden": {"exits": {"inside": "living"}, "people": ["Sue"], "capacity": 3},
"bedroom": {
"exits": {"downstairs": "living", "jump": "garden"},
"people": [],
"capacity": 1,
},
}
We can get a simpler dictionary with just capacities like this:
{name: room["capacity"] for name, room in house.items()}
{'living': 2, 'kitchen': 1, 'garden': 3, 'bedroom': 1}
To get the current number of occupants, we can use a similar dictionary comprehension. Remember that we can filter (only keep certain rooms) by adding an if clause:
{name: len(room["people"]) for name, room in house.items() if len(room["people"]) > 0}
{'living': 1, 'garden': 1}
