过滤Json并添加自定义标记

import json

# 假设原始的Json数据
json_data = '''
{
  "employees": [
    {
      "firstName": "John",
      "lastName": "Doe",
      "age": 30,
      "department": "IT"
    },

      "firstName": "Jane",
      "lastName": "Smith",
      "age": 35,
      "department": "HR"
    }
  ]

# 解析Json数据
data = json.loads(json_data)

# 过滤数据并添加自定义标记
for employee in data["employees"]:
    if employee["age"] > 30:
        employee["isSenior"] = True
    else:
        employee["isSenior"] = False

# 生成新的Json数据
new_json_data = json.dumps(data, indent=2)
print(new_json_data)
