如何过滤json以组合结果

import json

# 假设原始JSON数据存储在data变量中
data = '''
{
  "employees": [
    {
      "firstName": "John",
      "lastName": "Doe",
      "age": 30,
      "department": "IT"
    },
    {
      "firstName": "Jane",
      "lastName": "Smith",
      "age": 35,
      "department": "HR"
    },
    {
      "firstName": "David",
      "lastName": "Johnson",
      "age": 40,
      "department": "Finance"
    }
  ]
}
'''

# 解析JSON数据
parsed_data = json.loads(data)

# 定义过滤条件：筛选出年龄大于等于35岁的员工
filter_condition = lambda employee: employee['age'] >= 35

# 过滤数据
filtered_data = [employee for employee in parsed_data['employees'] if filter_condition(employee)]

# 组合结果：将满足条件的员工的姓氏和部门组合成新的字符串
result = ', '.join([employee['lastName'] + ' (' + employee['department'] + ')' for employee in filtered_data])

print(result)
