Q&A
>>> print(service) の前は何をしましたか？
前提・実現したいこと
https://note.com/hidekiikeda/n/n90013275fad3 の記事を参考に、Googleカレンダーの情報をLINEで確認できるような Bot の作成をしています。
しかし、エラーを起こしてしまい、先に進めなくなっていました。
本来であれば、
>>> print(service) Please visit this URL to authorize this application: https://accounts.google.com/o/oauth2/auth?response_type=code&client_id=603178jpvbh5iabha70c6u93t7t1.apps.googleusercontent.com&redirect_uri=http%3A%2F%2Flocalhost%3A5122F&scope=https%3A2F2Fwww.googleapis.com%2Fauth%2Fcalendar.events&state=ypuBnAzB2O9w&access_type=offline
という返答が来て、ブラウザが立ち上がり Google のログイン画面が表示されるらしいです。どうすればそのような挙動になりますでしょうか？

コメントありがとうございます。
何をしたかと聞かれると、"他の記事を参考に色々してしまった。"という回答になってしまいます。
terminal を一度落としてしまったため、過去の記述はお見せできないのですが、残っているログは下記のようになります。

python quickstart.py でエラーになってますが、quickstart.py というのが「該当のソースコード」でしょうか。pickle.load でエラーになってるのはたぶん quickstart.py にエラーがある状態で実行したために token.pickle というファイルがおかし苦なってると思うので、token.pickle を消して再実行してみては。
また、python を実行していきなり print(service) してますが、service という変数が未定義なためエラーになります。たぶん credential() の結果を service に代入すべきなのかも？ でも、python quickstart.py として実行する方が正しい気がします。
参考記事は有料のため読んでませんので、間違ってたらごめんなさい。
アドバイスありがとうございます。token.pickle を消して再実行してみましたが同じようなエラーが出てきてしまいました。"credential() の結果を service に代入すべき"というアドバイスに関しては、スキル不足により、うまくトライできておりません。基礎的な知識をもたず、作りたいという意欲だけで作業を開始してしまったため、技術的なアドバイスを実行できず申し訳ありません。もう少し基礎学習を進めつつ引き続きこちらの問題に取り組もうと思います。
ありがとうございました。
そうですね、プログラミングをまったくご存じない方がいきなり LINE Bot を作るというのはかなり敷居が高いです。初心者向けの Python 入門書もいろいろあると思いますので、まずは基礎から勉強するのがいいと思います。
