我正在尝试计算天际线的面积（具有相同基线的重叠矩形）

building_count = int(input())
items = {} # dictionary, location on x axis is the key, height is the value
count = 0 # total area
for j in range(building_count):
    line = input().split(' ')
    H = int(line[0]) # height
    L = int(line[1]) # left point (start of the building)
    R = int(line[2]) # right point (end of the building)
    for k in range(R - L):
        if not (L+k in  items): # if it's not there, add it
            items[L+k] = H …
