Automation with Python — Practical Patterns

Python shines for the glue between systems: renaming batches, parsing reports, calling REST APIs and pushing values to PLCs or databases. A few disciplined patterns—virtual environments, logging, CLI arguments—turn throwaway scripts into small, useful tools.

• Use venv + requirements.txt for repeatability
• Log to file & console for supportability
• Wrap scripts with a simple CLI (argparse)
