从python文件访问json中的嵌套字典

如果您只是想从所有问候中获得标签“ greeting”标签的第一个答复，那就是，

json_value = {
    "intents": [
        {
            "tag": "greeting",
            "patterns": ["Hi there", "How are you", "Is anyone there?", "Hello", "Good day"],
            "responses": ["Hello, thanks for asking", "Good to see you again", "Hi there, how can I help?"],
            "context": [""]
        },
        {
            "tag": "goodbye",
            "patterns": ["Bye", "See you later", "Goodbye", "Nice chatting to you, bye", "Till next time"],
            "responses": ["See you!", "Have a nice day", "Bye! Come back again soon."],
            "context": [""]
        }
    ]
}


for intent in json_value['intents']:
    if intent['tag'] == 'greeting':
        response = intent['responses'][0]
print(response)
