本文主要是介绍【python】sort 排序,对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!
sort排序
from operator import itemgetter a = [ {'name':'小张', 'create_time':'2020-10-16 09:56'}, {'name':'小王', 'create_time':'2020-10-16 09:57'}, {'name':'小李', 'create_time':'2020-10-16 09:58'}, {'name':'小赵', 'create_time':'2020-10-16 09:59'} ] a.sort(key=itemgetter('create_time'), reverse=True) print(a) [ {'name': '小赵', 'create_time': '2020-10-16 09:59'}, {'name': '小李', 'create_time': '2020-10-16 09:58'}, {'name': '小王', 'create_time': '2020-10-16 09:57'}, {'name': '小张', 'create_time': '2020-10-16 09:56'} ]
sorted排序(不会修改原来变量)
import datetime def get_timestamp(date): return datetime.datetime.strptime(date,"%Y-%m-%d %H:%M:%S").timestamp() s1=[''2021-07-13 04:00:00', '2021-07-13 05:00:00', '2021-07-13 06:00:00''] s=sorted(s1,key=lambda date: get_timestamp(date))
