WHAT THIS MODULE COVERS

Practical Standard Library Tools

Handle time, structured collections, text patterns, and reproducible project environments with deliberate choices.

BEFORE YOU START

Files, objects, and iteration. You've built working programs.

WHAT YOU’LL BE ABLE TO DO

Use standard-library tools effectively (datetime, pathlib, contextlib), isolate project dependencies with virtual environments, and follow Python best practices (PEP 8).

THE LESSON SEQUENCE
