tweepy メモ書き

create App

https://apps.twitter.com/app/new

• callback url は空にする！！

requirements

pip install tweepy pyyaml

pyyamlはなんとなく

write code

解説

• class TwConfig
  • 省略
  • getattrを上手に使うともっときれいに書けるよ
• class tweepyAPI(tweepy.API)
  • user.friendsを使う実装だと、取得件数が決まっているので（print_friends_simple()を叩いてみるとわかるよ）、iterationしながらとってくる実装を作成
  • cursor をiterationするtweepy.Cursorを使ってます
• login
  • アクセストークンが保存されてなかったらブラウザを開いてPINコードが表示されるので入力してねみたいな実装
  • wait_on_rate_limit=True, wait_on_rate_limit_notify=Trueしないとすぐrate limitで死にます。死なない代わりに猛烈に遅いけど
