添付されたJSONをループして、データ内の各アイテムの名前と価格を表示しようとしています。私の問題は、ファーストネームと50倍以上の価格を印刷することを繰り返すことです。私は何が欠けていますか?次のアイテムを表示するにはどうすればいいですか?これは私がコードを基にしたサンプルデータです。PythonリクエストとJson forループ

マイコード

import json 
import requests 

request = requests.get('http://example.com/json') 

for item in request: 
    data = request.json() 
    data = data['items'][0] 
    price = data['salePrice'] 
    name = data['name'] 
    print name

答えて

それが原因でこの線のだ:ここで

data = data['items'][0] 

明示的にアクセスしたそのループの各反復の最初の項目。

代わりにこれを試してみてください:

data = request.json() 
items = data['items'] 

for item in items: 
    price = item['salePrice'] 
    name = item['name'] 
    print name 
+1

使用 'dict.get( 'PARAMETER_NAME'、defaul_valueを)'。いくつかの項目はパラメータをソーンしません。 – JRazor
