Just now I asked

Write a Python script that returns all of the accounts in an AWS organization with a given tag where the user specifies the tag key and value using command line arguments

I thought the code had to be wrong because it used concepts I had never heard of. This time it used the resource group API.

I have never heard of the API. But it does exist. I also couldn’t find sample code on the internet that did anything similar. But from looking at the documentation it should work. I learned something new today.

BTW, for context when I claimed to be a “subject matter expert” above, I work at AWS in Professional Services, code most days using the AWS API and I would have never thought of the solution it gave me.
