Architecting Reusable Python Libraries for Microservices

Extracting shared utilities from Python microservices into standalone packages is a crucial evolutionary step for growing backend architectures. When teams scale, duplicate logic for logging, authentication handling, database wrappers, and custom exception handling inevitably spreads across repositories. Copying and pasting this boilerplate introduces technical debt, drift between service behaviors, and heightened maintenance overhead. Moving this code into versioned internal libraries establish
