Solution: counting people in the maze
Solution: counting people in the maze¶
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 count the occupants and capacity like this:
capacity = 0
occupancy = 0
for name, room in house.items():
capacity += room["capacity"]
occupancy += len(room["people"])
print("House can fit {} people, and currently has: {}.".format(capacity, occupancy))
House can fit 7 people, and currently has: 2.
As a side note, note how we included the values of capacity and occupancy in the last line. This is a handy syntax for building strings that contain the values of variables. You can read more about it here or in the official documentation for the string format method.
