Python + Пример API Календаря Google - проблемы с SSL

Question

Я хотел запустить API Календаря Google для Python примерного приложения со страницы: https://developers.google.com/calendar/quickstart/python.

Я сделал все, как описано там, но потом, когда я хочу запустить сначала я перенаправлен на предоставление прав доступа к приложению (Google Auth), что я и делаю, но затем я постоянно получаю следующие следы стека

Process finished with exit code 1

Я пробовал несколько разных подходов, чтобы исправить это, но все же без удачи, не могли бы вы помочь мне, пожалуйста?
