I did something similar to learn Go & gRPC. I had a python client for displaying a simple COVID-19 report with the option to export as CSV, and had a Go server that sent a request to a public API to collect the data for the report. Did I need gRPC or the Go server? Not really, but when you're learning something new, there's a certain psychological benefit to being able to finish something using the technology you're learning. That, and you can focus more on the learning part instead of getting sidetracked by the other details of a larger project.
