Question

我必须使用Python将这个input.json代码转换为输出响应。我在python 3中创建输出字典时遇到问题。请帮助我，我是python的新手。预先感谢。

Input.json

{
"function":"sample-text-function",
"questions":[
    {
        "instruction":"Hello! I'm Elth. I'm your personal assistant."
    },
    {
        "text":"Before starting please tell me your first name",
        "var":"first_name"
    },
    {
        "text":"Please tell me your last name",
        "var":"last_name"
    },
    {
        "text":"And your gender?",
        "options":[
            "Male",
            "female"
        ],
        "var":"gender"
    },
    {
        "text":"May I know your age?",
        "var":"age"
    },
    {
        "conditions":[
            [
                "age.isdigit() == False"
            ]
        ],
        "text":"I couldn't quite get how that response can be your age :/ Please enter your valid age.",
        "var":"age"
    },
    {
        "instruction":"Congratulations! Registration Successful."
    }
]

}

Output.json

    {
  "stage1": {
    "Bot Says": [
      {
        "message": {
          "text": "Hello! I'm Elth. I'm your personal assistant."
        }
      },
      {
        "message": {
          "text": "Before starting please tell me your first name"
        }
      }
    ],
    "User Says": "Srinath"
  },
  "stage2": {
    "Bot Says": [
      {
        "message": {
          "text": "Before starting please tell me your last name"
        }
      }
    ],
    "User Says": "Akula",

  },
  "stage3": {
    "Bot Says": [
      {
        "message": {
          "text": "And your gender?",
          "quick_replies": [
            {
              "content_type": "text",
              "title": "Male",
              "payload": "male"
            },
            {
              "content_type": "text",
              "title": "Female",
              "payload": "female"
            }
          ]
        }
      }
    ],
    "User Says": "Male"
  },
  "stage4": {
    "Bot Says": [
      {
        "message": {
          "text": "May I know your age?"
        }
      }
    ],
    "User Says": "what's your age?"
  },
  "stage5": {
    "Bot Says": [
      {
        "message": {
          "text": "I couldn't quite get how that response can be your age :/ 
Please enter your valid age."
        }
      }
    ],
    "User Says": "31 yrs"
  },
  "stage6": {
    "Bot Says": [
      {
        "message": {
          "text": "Congratulations! Registration Successful."
        }
      }
    ]
  }
}

到目前为止我的代码

例如，我只是试图在输出字典中插入一个值，并且出现错误

import json
from pprint import pprint
from collection import

with open('assignment_1_input_1.json') as f:
    data=json.load(f)
output=dict(dict(list(dict(dict()))))

output['stage1']['Bot Says'][0]['message']['text']=data['questions'][0]['instruction']

print(output)

我得到的错误

line 11, in <module>
output['stage1']['Bot Says'][0]['message']['text']=data['questions'][0]['instruction']
KeyError: 'stage1'

Answer 1

此行：

output=dict(dict(list(dict(dict()))))

实际上只是创建一个没有任何子字段的空字典，等效于

output = {}

您必须先声明每个子字段，然后再进行深入研究。实际上，

output['stage1'] = {}

有效，而：

output['stage1']['Bot Says'] = {}

没有。

我建议您使用所需的键初始化dict和每个子对象，例如：

 output = {}
 quick_reply = {'content_type': None, 'title': None, 'payload': None}
 message = {'quick_replies': [], 'text': None}
 bot_says = {'message': message}
 user_says = {'User Says': None}

 n_stages = 4
 for n in range(1, n_stages):
     stage_name = 'stage' + str(n)
     output[stage_name] = {'Bot says': [bot_says], 'User Says': None}}

然后根据需要填写。

输出：

{'stage1': {'Bot Says': [{'message': {'quick_replies': [], 'text': None}}], 'User Says': None},
'stage2': {'Bot Says': [{'message': {'quick_replies': [], 'text': None}}], 'User Says': None},
'stage3': {'Bot Says': [{'message': {'quick_replies': [], 'text': None}}], 'User Says': None}}

如何使用python3将此input.json代码转换为output.json？
