我怎样才能让它更好地使用这个 json 检查器功能？PYTHON

莫里西·沃兹尼察

我是一个初学者pythonist。我希望有人能看看我的功能并给我反馈。我觉得存在一种最佳且更简单的方法来检查分期付款价值。但我自己找不到。

案例：如果分期付款值> 100，则签入JSON。当分期付款<100时提供消息。

案件


my_json = [
   {
        "id": "A1",
        "price": 43900,
        "products": [
            {
                "product": "cash",
                "installment": 43900
            },
            {
                "product": "loan",
                "installment": 469.57
            }
        ]
    },
    {
        "id": "A2",
        "price": 99900.00,
        "products": [
             {
                "product": "cash",
                "installment": 99900.00
            },
            {
                "product": "loan",
                "installment": 1053.49
            }
        ]
    },
    {
        "id": "A3",
        "price": 56900,
        "products": [
            {
                "product": "cash",
                "installment": 56900
            },
            {
                "product": "lease",
                "installment": 285.05
            },
            {
                "product": "loan",
                "installment": 65.12
            }
        ]
    }
]

我的检查分期付款价值的功能

def instalments_check():
    for obj in my_json:
        for key, value in obj.items():
            if key == "products":
                for k in value:
                    for key1,value1 in k.items():
                        if key1 == "installment":
                            if value1 >= 100:
                                print("installment is correct")
                            if value1 <= 100:
                                print("installment is incorrect in {}".format(obj))

instalments_check()

您可以直接访问字典的键，而不是遍历它们。这样的事情会更容易遵循。

def installments_check():
    for obj in my_json:
        for product in obj['products']:
            if product['installment'] >= 100:
                print("installment is correct")
            else:
                print("installment is incorrect in {}".format(obj))
