python根据日期将json对象排序到不同的有效负载

import json
from datetime import datetime

# 假设有一个包含JSON对象的列表
json_objects = [
    {"date": "2022-01-01", "data": "payload1"},
    {"date": "2022-01-02", "data": "payload2"},
    {"date": "2022-01-01", "data": "payload3"},
    {"date": "2022-01-03", "data": "payload4"}
]

# 将日期字段转换为datetime对象并排序
sorted_objects = sorted(json_objects, key=lambda x: datetime.strptime(x["date"], "%Y-%m-%d"))

# 根据日期分组到不同的有效负载
payloads = {}
for obj in sorted_objects:
    date = obj["date"]
    if date not in payloads:
        payloads[date] = []
    payloads[date].append(obj)

# 打印结果
for date, payload in payloads.items():
    print(f"日期: {date}")
    print(f"有效负载: {json.dumps(payload)}")
    print()
