Writing Beautiful, Simple, and Safe Operations Scripts with Python
summary
A small wrapper around Python’s subprocess called Spix library provides a single typed run() API that handles signals, timeouts, logging, retries and returns a typed result object; it replaces dozens of brittle CI bash scripts at Smitten. Examples show verifying AWS CLI version, running terraform init/plan with retry on "text file busy" and using temporary directories, yielding Python exceptions and stack traces for diagnostics instead of opaque zero return codes.
