python - 如何在 Python 中迭代 JSON 列表

Question

我有这样的Json：

sampleJson = {"tld":".id","pricing":{"register":"225000.00","renewal":"225000.00","transfer":"225000.00"}},{"tld":".co.id","pricing":{"register":"285000.00","renewal":"285000.00","transfer":"285000.00"}},{"tld":".biz.id","pricing":{"register":"40000.00","renewal":"40000.00","transfer":"40000.00"}}

我想要这样的结果：

tld : .id
pricing :
register : 225000.00
renewal : 225000.00
transfer : 225000.00

请帮助python代码进行迭代

Answer 1

假设

sampleJson = [{"tld":".id","pricing":{"register":"225000.00","renewal":"225000.00","transfer":"225000.00"}},{"tld":".co.id","pricing":{"register":"285000.00","renewal":"285000.00","transfer":"285000.00"}},{"tld":".biz.id","pricing":{"register":"40000.00","renewal":"40000.00","transfer":"40000.00"}}]

for item in sampleJson:
    print(f'tld: {item["tld"]}')
    print('pricing :')
    for key, value in item["pricing"].items():
        print(f'{key} : {value}')

输出 -

tld: .id
pricing :
register : 225000.00
renewal : 225000.00
transfer : 225000.00
tld: .co.id
pricing :
register : 285000.00
renewal : 285000.00
transfer : 285000.00
tld: .biz.id
pricing :
register : 40000.00
renewal : 40000.00
transfer : 40000.00

Answer 2

汤姆罗恩的回答当然非常适合这种情况，但如果数据中的键发生变化，则需要更改固定字符串。更通用的解决方案是：

def recurse_dict(d):
    for k, v in d.items():
        if isinstance(v, dict):
            print(k,':')
            recurse_dict(v)
        else:
            print(k, ':', v)

for d in sampleJson:
    recurse_dict(d)

Answer 3

您可以定义一个递归打印字典的函数，如下所示：

sampleJson = {"tld":".id","pricing":{"register":"225000.00","renewal":"225000.00","transfer":"225000.00"}},{"tld":".co.id","pricing":{"register":"285000.00","renewal":"285000.00","transfer":"285000.00"}},{"tld":".biz.id","pricing":{"register":"40000.00","renewal":"40000.00","transfer":"40000.00"}}

def recursive_dict_print(d):
    for k in d:
        if isinstance(d[k], dict):
            print(k, ": ")
            recursive_dict_print(d[k])
        else:
            print(k, ":", d[k])

for d in sampleJson:
    print("next dict")
    recursive_dict_print(d)
