使用floatparse将json对象的值从数组中的字符串转换为数字

import json
from decimal import Decimal

def floatparse(obj):
    if isinstance(obj, list):
        return [floatparse(item) for item in obj]
    elif isinstance(obj, dict):
        return {key: floatparse(value) for key, value in obj.items()}
    elif isinstance(obj, str):
        try:
            return int(obj)
        except ValueError:
            try:
                return float(obj)
            except ValueError:
                return obj
    else:
        return obj

# 示例JSON字符串
json_str = '{"numbers": ["1.23", "4.56", "7.89"]}'
# 解析JSON字符串
json_obj = json.loads(json_str)
# 将数组中的字符串值转换为数字
parsed_obj = floatparse(json_obj)
# 打印转换后的结果
print(parsed_obj)

{'numbers': [1.23, 4.56, 7.89]}
