python-dotenvを使い環境変数を管理

python-dotenvを使い環境変数を管理

初めに

API_KEYなどPythonファイルにベタ書きだと使い勝手が悪いため
python-dotenvを使い環境変数を設定する

from datetime import timedelta

import pandas as pd
import tweepy

API_KEY = "xxx"
API_SECRET_KEY = "xxx"
ACCESS_TOKEN = "xxx"
ACCESS_TOKEN_SECRET = "xxx"


def twitter_api() -> tweepy.API:
    auth = tweepy.OAuthHandler(API_KEY, API_SECRET_KEY)
    auth.set_access_token(ACCESS_TOKEN, ACCESS_TOKEN_SECRET)
    return tweepy.API(auth)

python-dotenvバッケージをインストール

$ pip install python-dotenv

使い方

.envファイル作成

API_KEY = "xxx"
API_SECRET_KEY = "xxx"
ACCESS_TOKEN = "xxx"
ACCESS_TOKEN_SECRET = "xxx"

settigs.py作成
.envからデータを読み込む

import os
from os.path import dirname, join

from dotenv import load_dotenv

load_dotenv(verbose=True)

dotenv_path = join(dirname(__file__), ".env")

API_KEY = os.environ.get("API_KEY")
API_SECRET_KEY = os.environ.get("API_SECRET_KEY")
ACCESS_TOKEN = os.environ.get("ACCESS_TOKEN")
ACCESS_TOKEN_SECRET = os.environ.get("ACCESS_TOKEN_SECRET")

元Pythonファイル変更

from datetime import timedelta

import pandas as pd
import tweepy

from settings import API_KEY, API_SECRET_KEY, ACCESS_TOKEN, ACCESS_TOKEN_SECRET


def twitter_api() -> tweepy.API:
    auth = tweepy.OAuthHandler(API_KEY, API_SECRET_KEY)
    auth.set_access_token(ACCESS_TOKEN, ACCESS_TOKEN_SECRET)
    return tweepy.API(auth)

何がいいか

環境変数が散らばると参照がし難い、セキュリティ的にも良くない
python-dotenを使うと.envに集約できる
