TL;DR Show me the code!

In a recent project, I used gRPC over TLS between two services written in Go and Python. Writing TLS secured gRPC server and client in Go was effortless since it’s well covered with documentation. Plenty of blog posts and Stack Overflow answers on that topic. However, finding a workable example for Python + mTLS was very difficult. Once I figured out how to make it work, I feel obliged to document all the findings in a blog post.
