jsonから値を抽出し、Pythonを使用してフィルタリングします

Question

私はPythonにはとても新しいです。私はそれを学んでいます。

次のjsonデータを含むjsonファイルがあります。

{ 
"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" 
    } 
] 
} 
} 

まず私は、次のフィールドを抽出したいとフィールドを抽出した後、私はスコアが最も高い「tone_name」が必要です。

"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" 
     } 
    ] 

私の出力は次のようにする必要があります：私のコードは

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']) 

マイdata.jsonファイルは基本的に、あなたがちょうどここにやりたい

"{\n \"document_tone\": {\n \"tone_categories\": [\n  {\n    
\"category_id\": \"emotion_tone\", \n  \"tones\": [\n

Answer 1

が含まれている喜び

あなたがトーンのリストを取得してから各トーンをループするまで、そしてそのトーンのためにあなたの方法をナビゲートしなければなりませんEここにあなたの固定コードですその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 

をプリントアウト

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'])
