Question

我想将多个列表合并到一个JSON数组中。这是我的两个列表：

address =  ['address1','address2']
temp = ['temp1','temp2']

我通过以下调用合并两个列表，并创建一个JSON。

new_list = list(map(list, zip(address, temp)))
jsonify({
    'data': new_list
})

这是我的通话结果：

{
    "data": [
        [
            "address1",
            "temp1"
        ],
        [
            "address2",
            "temp2"
        ]
    ]
}

但是，我想收到以下问题。我该怎么做以及如何插入标识符address和hello。

{
    "data": [
        {
            "address": "address1",
            "temp": "temp1"
        },
        {
            "address": "address2",
            "temp": "temp2"
        }
    ]
}

Answer 1

您可以使用列表理解：

import json

address =  ['address1','address2']
temp = ['temp1','temp2']

d = {'data': [{'address': a, 'temp': t} for a, t in zip(address, temp)]}

print( json.dumps(d, indent=4) )

打印：

{
    "data": [
        {
            "address": "address1",
            "temp": "temp1"
        },
        {
            "address": "address2",
            "temp": "temp2"
        }
    ]
}

Answer 2

您可以像这样更改现有代码。该lambda函数将完成将其转换为字典的技巧。

address =  ['address1','address2']
temp = ['temp1','temp2']

new_list = list(map(lambda x : {'address': x[0], 'temp': x[1]}, zip(address, temp)))

jsonify({
    'data': new_list
})
