【python】sort 排序

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))
