如何解析JSON并在Python中将2个字段放在字典中？

Question

我想解析JSON文件并从JSON获取两个字段并将它们放在字典中。例如：

{
    "food": [{
            "name": "pasta",
            "type": "blabla",
            "sauce": [{
                    "name": "cream",
                    "url": "http://www...."
                }
            ]
        }, {
            "name": "pizza",
            "type": "bla",
            "sauce": [{
                    "name": "Tomato",
                    "url": "http://www...."
                }
            ]
        }
    ]
}

我想得到：

{pasta: cream, pizza: Tomato}

Answer 1

dict comprehension可以胜任：

data = {
    "food": [{
            "name": "pasta",
            "type": "blabla",
            "sauce": [{
                    "name": "cream",
                    "url": "http://www...."
                }
            ]
        }, {
            "name": "pizza",
            "type": "bla",
            "sauce": [{
                    "name": "Tomato",
                    "url": "http://www...."
                }
            ]
        }
    ]
}

foods = data['food']
print( {food['name']:food['sauce'][0]['name'] for food in foods})
