Pyhon3系でGoogle Driveと接続する その2:ファイルのアップロード

shuzo-kino.hateblo.jp
の続きでファイルをアップロードする部分をやっていく予定の枠

実際のところ

前回のquickstart.pyをベースに
developers.google.com

Scopeは公式サイトから'https://www.googleapis.com/auth/drive'に設定
OAuth 2.0 Scopes for Google APIs  |  Google Identity  |  Google Developers

アップロードファイルは仮にimage100.jpgというのを用意してやりました。
