如何在json数据中查找最低记录以及如何在json数据中查找总页面记录

import json

def find_lowest_record(json_data):
    data = json.loads(json_data)
    lowest_record = None
    lowest_value = float('inf')  # 初始化为正无穷大

    for record in data:
        value = record['value']  # 假设每个记录都有'value'字段
        if value < lowest_value:
            lowest_value = value
            lowest_record = record

    return lowest_record

# 示例JSON数据
json_data = '''
[
    {"id": 1, "value": 10},
    {"id": 2, "value": 5},
    {"id": 3, "value": 8},
    {"id": 4, "value": 3}
]
'''

lowest_record = find_lowest_record(json_data)
print(lowest_record)

import json

def calculate_total_pages(json_data, records_per_page):
    data = json.loads(json_data)
    total_records = len(data)
    total_pages = (total_records + records_per_page - 1) // records_per_page

    return total_pages

# 示例JSON数据
json_data = '''

    {"id": 1, "name": "John"},
    {"id": 2, "name": "Alice"},
    {"id": 3, "name": "Bob"},
    {"id": 4, "name": "Emily"},
    {"id": 5, "name": "David"}
]
'''

records_per_page = 2
total_pages = calculate_total_pages(json_data, records_per_page)
print(total_pages)
