字典、列表之间相互嵌套

列表中嵌套字典

employee_1 = {'name': 'david', 'dept': 'ops', 'post': 'NOC', 'salary': 12000, 'id': 113}
employee_2 = {'name': 'brain', 'dept': 'auto', 'post': 'DBA', 'salary': 13000, 'id': 115}
employee_3 = {'name': 'chris', 'dept': 'search', 'post': 'PJM', 'salary': 20000, 'id': 150}
employees = [employee_1, employee_2, employee_3]
