python中多对象动态Json文件的解析及字典插入

import json

# 假设我们有一个名为data.json的文件，内容如下：
# {
#     "users": [
#         {"id": 1, "name": "Alice"},
#         {"id": 2, "name": "Bob"}
#     ]
# }

# 读取并解析JSON文件
with open('data.json', 'r') as file:
    data = json.load(file)

# 插入新的用户数据
new_user = {"id": 3, "name": "Charlie"}
data['users'].append(new_user)

# 将更新后的数据写回文件
with open('data.json', 'w') as file:
    json.dump(data, file, indent=4)

try:
    with open('data.json', 'r') as file:
        data = json.load(file)
except json.JSONDecodeError as e:
    print(f"JSON解析错误: {e}")
    # 进一步处理错误，例如打印出错的行号或内容

if 'users' in data:
    data['users'].append(new_user)
else:
    data['users'] = [new_user]
