pythonでjsonファイルからの値取得

Last updated at Posted at 2018-03-12

pythonでjsonから値を取り出す。

たとえば、TwitterAPIで使うkeyたちをjsonファイルで管理したい。

こんな感じのjsonファイルを作成する。

config.json
{
    "api_key": {
        "CONSUMER_KEY": "xxxxxxxxxx",
        "CONSUMER_SECRET": "xxxxxxxxxx",
        "ACCESS_TOKEN": "xxxxxxxxxx",
        "ACCESS_TOKEN_SECRET":"xxxxxxxxxx"
    }
}

下記のようにすると、jsonから値を取り出せる。

app.py
# モジュールのインポート
import json

# ファイルを開く
json_file = open('config.json', 'r')
# JSONとして読み込む
json_obj  = json.load(json_file)

# 値の取り出し
CONSUMER_KEY        = json_obj['api_key']['CONSUMER_KEY']
CONSUMER_SECRET     = json_obj['api_key']['CONSUMER_SECRET']
ACCESS_TOKEN        = json_obj['api_key']['ACCESS_TOKEN']
ACCESS_TOKEN_SECRET = json_obj['api_key']['ACCESS_TOKEN_SECRET']

個人の趣味とかだと設定値系はついつい直書きしてしまうので、ちゃんと外だしするくせをつけたい。
