Clean Code and Engineering Standards - Module Overview
Why code quality is an engineering concern, not an aesthetic one - covering the mindset shift from code that runs to code that lasts.

Design and build professional Python command-line interfaces with argparse and Click - with proper help text, exit codes, stdin/stdout conventions, and composable commands.
Learn to identify the 15 most common code smells in Python code - the warning signs that indicate deeper design problems - and the refactoring that fixes each one.
Learn to write docstrings that actually help engineers - covering Google, NumPy, and Sphinx styles, when to document vs when to improve the code, and how to generate API docs automatically.
Use Black, isort, flake8, mypy, and pre-commit hooks to enforce code quality automatically - so engineers focus on logic, not formatting debates.
Names are the primary documentation. Learn how to name variables, functions, classes, modules, and constants so that code communicates intent without comments.
Master PEP 8 at engineering depth - not as a list of rules to memorize, but as a system of constraints that reduces cognitive load and enables collaboration at scale.
Learn how to structure Python projects for maintainability - from scripts to packages to full applications - using src layout, pyproject.toml, and clear module boundaries.
