Problem scenario
You want to use gRPC as a proof of concept. What should you do?
Solution
Go here: https://chromium.googlesource.com/external/github.com/grpc/grpc/+/chromium-deps/2016-08-17/examples/python/README.md
You may want to clone this repository:
https://github.com/grpc/grpc
(Look in the directory for the language of your choice; it should have an "examples" directory.)
For using gRPC with Python you can install a certain package; for assistance with this, see this posting.
