Question

我对python很新。我正在学习它。

我有json文件，其中包含以下json数据。

{
"document_tone": {
"tone_categories": [
  {
    "category_id": "emotion_tone", 
    "tones": [
      {
        "tone_name": "Anger", 
        "score": 0.041202, 
        "tone_id": "anger"
      }, 
      {
        "tone_name": "Disgust", 
        "score": 0.054272, 
        "tone_id": "disgust"
      }, 
      {
        "tone_name": "Fear", 
        "score": 0.080706, 
        "tone_id": "fear"
      }, 
      {
        "tone_name": "Joy", 
        "score": 0.813125, 
        "tone_id": "joy"
      }, 
      {
        "tone_name": "Sadness", 
        "score": 0.155878, 
        "tone_id": "sadness"
      }
    ], 
    "category_name": "Emotion Tone"
  }, 
  {
    "category_id": "writing_tone", 
    "tones": [
      {
        "tone_name": "Analytical", 
        "score": 0.0, 
        "tone_id": "analytical"
      }, 
      {
        "tone_name": "Confident", 
        "score": 0.0, 
        "tone_id": "confident"
      }, 
      {
        "tone_name": "Tentative", 
        "score": 0.0, 
        "tone_id": "tentative"
      }
    ], 
    "category_name": "Writing Tone"
  }, 
  {
    "category_id": "social_tone", 
    "tones": [
      {
        "tone_name": "Openness", 
        "score": 0.028, 
        "tone_id": "openness_big5"
      }, 
      {
        "tone_name": "Conscientiousness", 
        "score": 0.314, 
        "tone_id": "conscientiousness_big5"
      }, 
      {
        "tone_name": "Extraversion", 
        "score": 0.944, 
        "tone_id": "extraversion_big5"
      }, 
      {
        "tone_name": "Agreeableness", 
        "score": 0.982, 
        "tone_id": "agreeableness_big5"
      }, 
      {
        "tone_name": "Emotional Range", 
        "score": 0.865, 
        "tone_id": "neuroticism_big5"
      }
    ], 
    "category_name": "Social Tone"
  }
]
}
}

首先，我想提取以下字段，在提取字段后，我需要“tone_name”，得分最高。

 "tones": [
      {
        "tone_name": "Anger", 
        "score": 0.041202, 
        "tone_id": "anger"
      }, 
      {
        "tone_name": "Disgust", 
        "score": 0.054272, 
        "tone_id": "disgust"
      }, 
      {
        "tone_name": "Fear", 
        "score": 0.080706, 
        "tone_id": "fear"
      }, 
      {
        "tone_name": "Joy", 
        "score": 0.813125, 
        "tone_id": "joy"
      }, 
      {
        "tone_name": "Sadness", 
        "score": 0.155878, 
        "tone_id": "sadness"
      }
    ]

我的输出应该是：欢乐

我的代码是

import json
with open('data.json','r') as f:
for line in f:
    line = line.strip()
    print line
    parsedJson = json.loads(line)
    print parsedJson
    for tone in parsedJson['document_tone']['tone_categories'][0]['tones']:
        print(tone['tone_name'])

我的data.json文件包含

基本上要做你想做的事情，你只需要在dict中导航直到你得到你的音调列表，然后循环每个音调，并为那个音调打印出它的tone_name

parsedJson = json.loads(jsonFile)
for tone in parsedJson['document_tone']['tone_categories'][0]['tones']:
    print(tone['tone_name'])
# Anger
# Disgust
# Fear
# Joy
# Sadness

这是您的固定代码

import json

jsonText = None
with open('data.json','r') as f:
    jsonText = f.read()

parsedJson = json.loads(jsonText)

for tone in parsedJson['document_tone']['tone_categories'][0]['tones']:
    print(tone['tone_name'])

从json中提取值并使用python对其进行过滤
