OK David, I'm also a Linux newbie and my Linux PC has a dead power supply that I've been too sick to fix. Since it is a choice (given my limited energy resources), I've spent my time learning python on a very old Windows PC instead of reviving the Linux PC, and I've never used Google Apps.
However, looking at the links provided, this is how I'd proceed: 1) At https://developers.google.com/identity/protocols/application-default-cre dentials (Google Application Default Credentials | Google Identity Platform), are the insructions you need to follow. Now, I think you make up your own path and filename for the environment variable, the more iffy question is what file it shoud be. And the answer appears to be that it's a file you download. It then tells you to follow several instructions, using the https://console.developers.google.com/projectselector/apis/credentials page, to get a file that automatically downloads to your computer. 2) It then says you have to make the environment variable GOOGLE_APPLICATION_CREDENTIALS, specifying that it points to the file you just downloaded. I don't have a working Linux machine to test this on, at least it sounds like you're using Linux (let me know if you're using Windows and I can test it there), but to permanently set an environment variable in Linux: Edit ~/.bashrc and add the line: export GOOGLE_APPLICATION_CREDENTIALS=<path/filename> (instructions are different for Windows, or Linux using something other than bash for shell scripts) That's what you need to do, and then your youtube_search.py should work (haha, well you can try it and see).

If you're not running in Google Compute Engine, you need to make a file defining the credentials, and supposedly there are instructions or requirements in the link above. Looks like Anaconda tried to get the credentials by calling its _auth.default_credentials() function: credentials = _auth.default_credentials() from "python3.5/site-packages/googleapiclient/discovery.py", but it failed. I think you need to read that link and make the file it wants to find.
