如何在python中打印具有相同字段的多个json值

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

邮政编码：CB3 0FA 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)

邮政编码：CB3 0GT 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)

邮政编码：CB3 0英尺 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

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

输入邮政编码：CB3 0FA
您输入了邮政编码-->CB3 0FA
回溯（最近一次呼叫最后一次）：
文件“/py_script3.py”，第62行，在
最近的邮政编码（邮政编码）
文件“/py_script3.py”，第42行，最近的邮政编码
对于i的值['result']：
TypeError:列表索引必须是整数或片，而不是str

这应该可以使用格式化打印，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

请解释一下这里的问题是什么。我在最后的主要问题中添加了错误。。很抱歉输入邮政编码：CB3 0FA您输入的邮政编码-->CB3 0FA回溯（上次调用）：文件“/py_script3.py”，第62行，在最近的邮政编码（邮政编码）文件中“/py_script3.py”，第42行，在最近的邮政编码中输入i in value['result']：类型错误：列表索引必须是整数或切片，而不是在主要问题中添加的strI，我的apologies@garg_hbti我想说的是，问题在于如何加载json，能否修复帖子上的缩进并显示如何调用最近的jsonpostcode@garg_hbti如果您将该文件保存到

blah.json

中，然后加载它，它会工作，因此它必须与您加载它的方式有关，而不是实际的内容循环遗漏的是，我直接从loadJsonResponse（url）返回result部分，一旦我从那里删除了['result']部分，它就像一个符咒一样工作。谢谢
