Python：如何处理dict列表

我正在尝试存储此json中的折扣代码和金额。我不知道名单上会有多少条

  "discount_codes":[
     {
        "code":"STUDENT",
        "amount":"10.00",
        "type":"percentage"
     },
     {
        "code":"TEACHER",
        "amount":"15.00",
        "type":"percentage"
     }
  ]

我正在尝试这个，但它不起作用：

for codes, x in enumerate(discount_codes):
    discount_code = codes['x']['code']
    discount_amount = codes['x']['amount']
    print (discount_code)
    print (discount_amount)

枚举列表返回索引和值，如果值是字典，则从字典中获取值，代码如下：

for index, value in enumerate(discount_codes):
print(index)
print(value)
discount_code = value['code']
discount_amount = value['amount']
print(discount_code)
print(discount_amount)
#print (discount_code)
#print (discount_amount)

将完整的代码和执行添加为图像：

应该是

code[x]
