import heapq #用heapq 支持自定义对象 #heapq可以用默认list类型来创建堆结构, #用[]来创建堆结构不建议给初始值,如果非得给的话建议先调用heapq.heapify进行转化 import random a = [] for i in range(10): heapq.heappush(a, random.randint(1, 10)) print(a) #堆顶端总是放着堆中最小值 print(a[0]) # 让heapq 支持自定义对象 class Item: def __init__(self, id, name): self.id = id self.name = 'leo' #需要实现lt 特殊方法 def __lt__(self, other): return self.id < self.other item = [] for _ in range(10): num = random.randint(1, 10) heapq.heappush(Item(id=num)) print(item[0])
