如何在python中打印具有相同字段的多个json值

Question

我正试图从API接收的json输出中打印python中的json值，如下所示。你知道吗

邮编：CB3 0FA 国家：英国 地区：英格兰东部

邮编：CB3 0GT 国家：英国 地区：英格兰东部

邮编：CB3 0FT 国家：英国 地区：英格兰东部

def loadJsonResponse(url):
    return json.loads(req.urlopen(url).read().decode('utf-8'))['result']


def nearestPostcode(postcode):
    url = 'https://api.postcodes.io/postcodes/{}/nearest'.format(postcode)
    value = loadJsonResponse(url)
    for i in value['result']:
        zip_code = i['postcode']
        print (zip_code)

下面是我的Json输出：

我看到下面的脚本执行错误。你知道吗

Enter the postcode : CB3 0FA
You entered postcode--> CB3 0FA
Traceback (most recent call last):
  File "./py_script3.py", line 62, in <module>
    nearestPostcode(postcode)
  File "./py_script3.py", line 42, in nearestPostcode
    for i in value['result']:
TypeError: list indices must be integers or slices, not str

Answer 1

这应该可以工作，使用格式化打印，通过加载json输出进行测试

for i in value['result']:
    print('POSTCODE: {} England REGION: {}'.format(i['postcode'], i['region']))

POSTCODE: CB3 0FA England REGION: East of England
POSTCODE: CB3 0GT England REGION: East of England
POSTCODE: CB3 0FT England REGION: East of England
