数组排序

import heapq
nums = [10, 2, 9, 100, 80]
print(heapq.nlargest(3, nums))
print(heapq.nsmallest(3, nums))
students = [
    {'names': 'CC', "score": 100, 'height': 189},
    {'names': 'BB', "score": 10,  'height': 169},
    {'names': 'AA', "score": 80,  'height': 179}
]
print(heapq.nsmallest(2, students, key=lambda x: x['height']))

这个库非常好用，尤其取列表头部数据，最大几个，最小几个经常用到

运行结果

[100, 80, 10]

[2, 9, 10]

[{‘names’: ‘BB’, ‘score’: 10, ‘height’: 169}, {‘names’: ‘AA’, ‘score’: 80, ‘height’: 179}]
