To connect to BigQuery using Python, you will need to start with an IDE e.g. Pycharm or Visual Studio Code.

Assuming no prior programming experience, you can begin by :

1. Download Pycharm or any other IDE of your choice.
2. Write a simple Hello World program to make sure that your configuration is correct.
3. Enable BigQuery API and create credentials
4. Copy and paste the code from the article you referred with your own credentials.

Let me know if you get stuck.
