在python中从JSON查找最新日期

import json
from datetime import datetime

with open('data.json') as file:
    data = json.load(file)

latest_date = None
latest_item = None

for item in data:
    date_str = item['date']
    date = datetime.strptime(date_str, '%Y-%m-%d')
    if latest_date is None or date > latest_date:
        latest_date = date
        latest_item = item

print("最新日期:", latest_date.strftime('%Y-%m-%d'))
print("对应数据项:", latest_item)
