Passing the answer of Watson Assistant to a variable Python

I am trying to get the output of Watson Assistant into a variable. So as far as I have searched, i need to get the "output" and "text" part of the json (at first it is a dict, but then we parse it to a json). But I cannot seem to get it:

I have searched in these 2 questions already:This one for watson This one for parsing the json

The code is really simple: accessing to my bot, and inputting "trips". I've taken out the api and workspace, but I have them (obviously).

if __name__ == '__main__':
    assistant = watson_developer_cloud.AssistantV1(

        iam_apikey='{YOUR API HERE}',
        version='2018-09-20',
        url='https://gateway-syd.watsonplatform.net/assistant/api'
    )

    response = assistant.message(
        workspace_id='{YOUR WORKSPACE HERE}',
        input={
            'text': 'trips'
        }
    ).get_result()
    fullResponse=json.dumps(response, indent=2)
    print(fullResponse)
    print("testing to print the output: ")
    respuesta=json.dumps(response, indent=2)
    #print(respuesta['output'][0]['text'])
    print(respuesta['output']['text'])

And the output:

Traceback (most recent call last):
  "intents": [
  File "C:/Users/.PyCharmCE2018.3/config/scratches/pruebaMain.py", line 105, in <module>
    {
    print(respuesta['output']['text'])
      "intent": "trips",

      "confidence": 1
    }
  ],
  "entities": [],
  "input": {
    "text": "trips"
  },
  "output": {
    "generic": [
      {
        "response_type": "text",
        "text": "We got trips to different countries! Type continents to know more!"
      }
    ],
    "text": [
      "We got trips to different countries! Type continents to know more!"
    ],

  },

      "initialized": true,

        }
      ],

      "dialog_request_counter": 1,
      "_node_output_map": {

          "0": [
            0
          ]
        }
      },
      "branch_exited": true,
      "branch_exited_reason": "completed"
    }
  }
}
testing to print the output: 

Process finished with exit code 1

So I want to get the answer of "We got trips to different countries! Type continents to know more!". I have read the documentation of the python API and some more info (https://github.com/IBM-Cloud/watson-conversation-variables) of but can't seem to find anything. I also tried accessing the json variable with $but did not work.

You don't have to use json.dumps here, you can directly use the response JSON returned from the service as shown in the code snippet below

import watson_developer_cloud

if __name__ == '__main__':
    assistant = watson_developer_cloud.AssistantV1(

        iam_apikey='APIKEY',
        version='2018-09-20',
        url='https://gateway.watsonplatform.net/assistant/api'
    )

    response = assistant.message(
        workspace_id='WORKSPACE_ID',
        input={
            'text': 'trips'
        }
    ).get_result()

    print(response)
    print(response['output']['text'][0])
