Packaging a Quantitative Model

A batch job and a test suite need a stable way to import the pricing engine. This lesson installs the supplied teaching package, traces its public API and runs it from a configuration file. The package keeps the pricing formula separate from file handling and reporting.

• draw a minimal src/mypkg/ layout with __init__.py and focused modules;
• import a pricing function from a separate runner script;
• state what belongs in the package versus scripts versus notebooks;
• explain "ship the model" as an installable, testable API.
